Hey guys what up, So ive got a 1992 Aztec green gsr and heres my prob. Im about to supercharge it hopefully but every once and a while my car will just fall flat on her face, when i start to drive i feel it loose a good 60% of power between 1k-3k and it regains it when i push into her a lil more. When I drive it sometimes long trips to vegas well 100 miles i'll be driving and my tach will drop my car will stumple when it does but then quikly regain itself. It done it a few times.. I think its my dizzy but i dunno. It is very weird. It has died once when i started it from this and that was it. I always warm up my car b4 i drive and i only run 91oct. I am almost 100% sure its not a fuel issue because i have full pressure when it has messed up plug all of it is brand new
new walbro 255lph new filter
So i am just stuck, I baught the car with a shitty autozone dizzy and i am starting to think that would be the cause of it because it does control my tach input and would make a symptom like i am havin i believe. But i am unsure ive checked all wires and nothing is loose broken and when the car mess's up ive never gotten a check engine light and i know my cell is workin properly also..

And when i am drivin around 70 and it does fall i mean it's like it dies and quiklu restarts almost instanly.. and the tach falls and jump and is crazy with then engine as well
please help me..

 

Could be the distributor, sounds like it may need a tune up. Always start with checking the basics and go from there.

 

thanks for your input but its not a tune up i wish, the car just had everything done to it 3 months ago plugs wires dizzy the works, I just wanna find out if anyone else has had a simular prob and was it the dizzy cause i know its not a fuel issue for sure now. and also ive checked my plugs and they are in great condition as well. the cars runs great just stumbles sometimes. she passes smog with flying colors

 

check your ground wires, specifically the transmission to chassis and thermostat housing. Use a ratchet to make sure.

 

Sounds like you have a dead spot in your TPS...
Does the problem seem to occur at the same throttle angle most of the time? Like around 25%?

 

It could be your TPS sensor when mine started going bad the car would fall on its face then if u steped on it be fine again. I picked up a blox one and that solved that issue



check the spark plugs make sure there in there good, had one loose and it would fall on its face.

 

Ok i have checked all my ground wires and they are all dead tight. It seems to be doing it around 65mph round 4k everytime the tach jumps round and the car feels like it dies and starts right back up. I am going to check my tps is their anyway i can check its resistance to see if its faulty?
I checkedmy plugs like a week ago and they are in mint shape so I dunno whats the prob, ive heard of ppl buyin dizzy from autozone and havin simular probs and i never thought about the tps, It doesnt always do it. Id say its done it twice outta 6 times drivin to vegas. which is 101 miles my door to my parents house, So i dunno....but is their ne way to check resistance and what kinda resistance would i be lookin for

 

back probe the sensor and set your meter to volts. Key on. Check for about .5 volt with throttle closed. have someone SLOWLY open the throttle to 100%.

You should see the voltage rise to about 4.5. If at any point you lose voltage, there is your dead spot...
You can check resistance by unplugging the tps and watching the resistance also...
The tachometer jumping around is sometimes a sign of the igniter going bad...
Good luck!

 

Thanks for your input and I will be checking it tonight once im home.
Whats resistance would be 0% to make sure it is properly calibrated at zero throttle?
And im going to check my igniter also thanks again for the valueble info.

 

He said .5v when the throttle is closed and 4.5v when it's open all the way. Set your meter to 12v when you take your reading.

 

ok so I checked it thismorning and its went perfectly from .5v all the way to 4.5v with out losing a digit anywhere and even right back down so no dead spot damnit, Is their anyways i can check my igniter witout buying a new one first? Thanks everyone for your input it is much appreciated and all my ground wires are on solid as well...I gotta drive her to vegas today and I just am hopin she doesnt stumble on me again today

 

In the past on my Hondas, when the tachometer starts going crazy and the engine starts to miss, there's been a grounding issue.

However, just this last weekend the tach went crazy on my Skyline. Turned out to be the igniter.

Unfortunately, you cannot buy distributor internals separately. You must either part out an existing distributor and selectively replace the components in question, or buy a complete unit.

When I replaced my distributor a few years back I got one from importrp.com. Looks like you can get a complete unit for around $200 for a '92 GSR:

First off I would like to say I miss Wa and hows the weather lol, Yeah i was lookin into it thismorning and your right i cant buy the parts damnit, But is their any way i can check to see if that is the prob for sure? A shop in vegas has the dizzy brand new td44u for 150 with a 1yr warranty so i might pick that up today but i dont wanna waste money on stuff thats not going to fix it but i truly do believe my prob is sumwhere in my dizzy...just want to know if their is any way to check it an see....

 

A repair manual should be able to show you how to check to see if it's good using a multimeter.

 

You used to be able to buy them aftermarket a few years ago. I remember buying one for like 60-80 bucks. I broke down in some hicktown in Alabama. pulled into an autozone or something and they had one, I bought it,installed it, and our road trip continues!
But for all intensive puroposes, the easiest way to test the igniter is to substitute a known good one...

 

"Intents and purposes"... sorry, couldn't help myself

 

s ok update lol, Car acted even worse on trip yesturday to vegas, Didnt do its normal loss of power at high speeds. It happend twice. Once while I was leaving my home town for vegas starting off in first gear the car lost about 70-90% of its power in first gear gave her about 20% more throttle got past it and then once more about 63 miles later at the check point same thing, Leaving the checkpoint and in first gear she just lost mass power gave her more throttle and she scooted along fine, Im in vegas today buying my lady a new vw jetta so once I am back i am going to swap dizzys with a friend of mine but the car does it so random that i dunno if it will even do it when i have his cause i can only use it for the day.. So i am going to see if that will help but i dunno. Thanks again everyone for your input and i'll let you all know whats up after i buy my new car!

 

Thanks lol, i didnt even spell it right either...

 

Try replacing your spark plug wires. Here is another instance of an experienced owner overlooking or over thinking a simple problem. http://www.hondata.com/forum/viewtop...3a42455fa3d7f3

 

lol first thing i checked, I warranted them out for a new set also and still no difference, I used my friends dizzy but i did have it long enough to see if the problem would reoccur, I dunno what to do... Is their any kinda resistance i can check on my igniter to see if it is truly faulty or what? Cmon ppl help me outl. I wish it were sumthing simple but its not. Ive already checked everythign simple an now im on the bigger itiems of what it could be.. Thanks fore everyones help and when i do properly diagnose this problom ill be sure to never forget it lol. Its been a royla pain in my ***

 

did you check all grounds ? is there a cel? check for a vacum leak that could possibly only cause a problem under light load and light thorttle in first gear.

 

Intermittent electrical problems are always a pain in the ***.
Since you describe being able to "push through it" like when the throttle passes a certain percent- Makes it sound like a intermittently failing TPS sensor...

But that doesnt explain the tach jumping around...Does the rotor fit snugly on the distributor shaft? Im kinda thinking distributor now....Hmmm.

 

my old db2 did similar things as well. I opened up the distributor and cleaned out all the contacts. I had noticed some of the wires and contacts were really corroded. Un screwed some of them and cleaned them off.

 

If it is not a plug wire problem, a jumping tach is frequently an indication of an impending failure of the igniter. Try replacing you igniter, as the only test Honda publishes I am aware of basically looks at the inputs and if they are good they deduce the ICM must be bad. Here is their test:

 

wow thanks everyone for the input, The car is at my rents in vegas and i am goin to pick her up today as soon as I get to vegas i'll be checking my igniter, I have already checked tps for deadspots and its workin perfect all my grounds are perfect and all my vaccume lines are intact, i will post pics tonight of the engine its got all the factory **** so it passes smog with flying colors.. every vaccume line that was in it from honda is still in it lol. But like I said tonight i wil be checking my igniter DB2 thanks a lot for ur times and everyone else. I just want to get it running right b4 I sc or turbo it im undecided which to do and cant do either untill this prob is identified and fixed.
