alright when i am driving and i start accelerating... my car bogs around 3.5 k... and it drops down to 3k... then back up to 3.5 and then its fine... and then i slow down.. and start accelerating again... and the same thing.... i dont know what it is.... thinking plugs? cuz my wires rotor and cap are new.... Im tryin to figure it out... it feels like its bad flow... which makes me think o2 sensor... but anyone else have this problem?

help much appreciated

 

is it doing it durring part throttle or wide open throttle? Need more info

 

ummm...part...i dont usualkly go wot

 

I had something like that happen to me and it was shitty wires. (see: defective wires)

 

Could be a bad TPS.

 

does it have a CEL? if not, and if the car has a good tune up, it is most likely the ignitor.

 

I'll rule out TPS if he's acclerating slowly. TPS acts as an accelerator pump and gives the engine a burst of fuel when you lay into it quick, so essentially you could accelerate really slowly without a tps and you wouldn't shouldn't notice a difference. Plus a TPS would set a code if it were starting to get erroneous values, most likely. Ignitor is a possibility, that is one of the few achilies' heel of a honda. Although i'd say if it's at part throttle it could be an oxygen sensor that isn't reading properly.

Stand on it WOT and tell us how it runs.

 

it usually doesnt bog at WOT... umm it was like IDLING really high and then i picked up the o2 sensor wire and kinda messed with them.. and the idle changed... so how much is an 02 sensor?

 

sounds like a fuel problem

 

bad fuel? i use 90 octane from shell. wat would cause the cars engine to just all of a sudden like ose rpms? It feels like a missfire.... like one of the cylidners everynow and then just stops working and then works again...

 

When was the last time you changed the fuel filter? low fuel flow could cause your problem

 

i've got 20 bucks riding on bad O2 sensor/wiring. Any takers?

I didn't read anything after this.
But I would say a good thing to check is your fuel pump.
Sounds like your car is starving.

 

well my pump primes... and the filter is brand new... and so is my dizzy.... so i dunno.... i do think o2 sensor as well.... i got in the car today and drove and i thought i smelt unburnt fuel.... so.... mabye its sending too much? or sumthin.... i get a code for my IAT sensor. but i dunno...

 

I was just going to say IAT next, because that WILL cause a problem. I had bad wiring to mine (i had to extend it), and it was causing misfiring like crazy above 5k rpm. So check the sensor and the wiring. If that wire has any sort of resistance it will cause serious problems (trust me i know )

 

wat about my gasket for the throttle body? cuz i just realized i didnt put a new one on there.....lol... so ill do that tmrw and then ill see.... and if the IAT is bad then i have another one... so... we'll see.

 

check the IAT wiring too. One wire should be ground, so test it with with a multimeter and make sure the resistance of the wire through the chassis is very low. Then backprobe the IAT wire on the computer, connect a jumper wire between the frame and t-pin, and then check resistance between the wire at the connector and the frame again. And i believe you can check the iat by doing resistance vs. ambient temp, but i'm not exactly sure how to do it and i don't have time to look in the service manual right now.

 

it was my TB gasket... got a enw one and bam it stopped... all good now... thanks for tha help guys..

 

soundz good
