its an 88 hatch with a d15b2, when i stomp it, it'll sputter/hesitate. if i ease onto the gas it will work perfectly fine. i replaced plugs, wires, fuel filter, the guy that i bought it off said it has a "new" distributor and "new" injectors. is the timing off on this? any ideas?

 

Any CEL's?

 

none, it idles fine and rev's fine if i ease onto the pedal, its only sputtering/missing i put it straight to the floor. i also tried tightening the throttle cable some, had no effect

 

any1 have any suggestions or experience like this?

 

Im havin the same problem.i have to downshift to pick up sp3ed..i have a 95 d3lsol 1.6 sohc vtec motor in my 89 ef sedan..pleade help

 

i used to have the same issue on my d15 dpfi, i have gotten rid of the sputtering while driving by replacing the plugs, wires, and injectors...i wouldnt think the timing is off because that wouldnt cause sputtering just when you mash the gas, the car would run like crap all the time...personally i think its a fuel delivery issue...id begin with rechecking the injectors and work your way back

 

I had a similar problem on my old 88 dx. It was a bad ignitor in the distributor. If you got a friend w/ a dpfi ef, i would try just putting his distributor on your car. Only takes a couple minutes, just dont lose track where the plug wires go on the dizzy.

 

cool thanks i'll try to track one down. i checked the timing its dead on, checked the firing order its fine. i was about to attempt to haul the cat off to see if its clogged but it started snowing lol so the distributor sounds like a better thing to try next! i'll let ya know how it goes, thanks

 

also try changing your fuel filter...
i had that problem... i canged the fuel filter...the distributor..plugs and wires..

and it solved that

 

yea heres the list of things i've tryed so far - plugs, wires, fuel filter, adjusted throttle cable, checked timing, firing order. lol i just cant shake this and its driving me nuts, plus it started snowing today and this is suppose to be my winter car, i'd hate to have to drive my skyline in the winter

 

yea there is almost half a foot of snow here in north bay ontario... but yea try that distributor... its always worth a try.. lol your honda is gonna be almsot like new

 

if i had of known firstoff that i was replacing all of these things i probably would of just picked up a b18 swap lol ohwell she'll be good on gas! i look forward to it running right haha so i'll try to find some1 with a dizzy i can try out, and if thats not it i'll recheck the fuel system, the guy said it had new injectors put it when i bought it but maybe ones clogged or somethin.

 

im having the exact same problem with my 88 dx hatch
let me know if new distributor helps eh?
-austin

 

im having the same problem with my 90 hatch, i have a d16y5, so let me kno what it takes to fix it cuz i need my car ASAP

 

haha im trying to track down a distributor to test on it but the progress is slow, if any1 else can find one and try it let me know!

 

i hooked up a fuel pressure gauge and its showing about 34psi is this normal? im genna get my injectors cleaned to be on the safe side if it is then order a new diz

 

Are you ignition parts OEM? Make sure cap, rotor and wires are Honda. Also don't run anything else but NGK plugs.

Have you pulled your plugs and checked condition? Fuel pressure seems normal I dont know spec off top of head. Also, I would rule everything out instead of throwing parts at it like buying a distributor. It could just be the ignitor or coil and not need a whole distributor assembly. If it was something warranting a distributor replacement I would think you would have a cel for one of the sensors.

A leakdown test also might not be a bad idea.

 

It doesn't matter if he is running OEM Honda or any other well known company, there are some ignition components that are made better than OEM Honda.

Check your thermostat ground, and also make sure your TPS is operating correctly. Maybe he switched the TPS and MAP sensor wires, happened to a friend once, I had to save the day.

 

Map sensor. Check the wiring and especially the vacuum line going to it.

 

You don't think if he switched the connectors on TPS and map sensors that there would be a cel?

Also please list igntion parts that are better then OEM. Im sure the list of inferior ones will be 3 pages longer. For all we know he could be running some Autozone **** with autolite plugs.

 

everything on the car is stock oem spec right down to the new clutch i got for it. i refuse to use anything aftermarket on my supposed DD lol i have a skyline to waste every penny i earn on but i'm going to check the TPS, i have a spare throttle body here with another TPS on it that'll check as well if the one on the car is bad, i had a quick look at the wiring the map and TPS aren't switch. i really dont want to buy a new diz but the way things were leading it was looking like it might come down to it, and the fuel pressure goes up to 40psi when under any sort of load.

 

have you checked vacuum lines?

 

i checked vacuum lines, checked the TPS and it was reading between 4 and 5 volts (wouldn't go more accurate but closer to 5) we noticed that the upper butterfly valve on the intake was hesitating to open when the throttle was pinned. once it opened u could rev it all day. does any1 know if its suppose to be so hesitant to open? how to fix it? thanks everyone!

 

if your butterfly valve is sticking, you need to take the TB off and give it a good cleaning. It should open and close with ease.

 

yea i tried putting some oil on to lube it up a bit because it looked a little corroded and it helped it out a lot so i guess i'll get some cleaner and get to work on it tomorrow!
