Correct me if Im wrong but I think this issue has been covered before.

 

I will correct you, It is but Like that add says I just got the new stuff and its still doing it.. I just got the ecu today buddy and its still doing it and I have no idea why..

 

check the ignition timing.

 

I stand corrected.

 

I changed that and the **** is still doing ti I dont understand what the hell it could be but thanks everyone for helping...

 

On my caravan the same stuff was happening when my O2 sensor died...also a pain in the *** do diagnose on those cars. I son't know if this would be true on a honda

 

honestly i question some peoples imagination and the need for it answering some of these questions, hey mat wasnt one of the last suggestions a "bad ground"! look guys im the mechanic on the car, ive hit the tps and throttle boddy, the idle adjusting screw, new ecu, vaccuum hoses, and am now putting head and block to TDC, i doubt thats gonna do it, an o2 sensor wont throw it off, i had one go on mine, itsent a trouble code to ecu and check engine light stayed on, throttle cable is fine, iacv is reading correct volts and there are no csreens in the unit, this is a 96 lx the throttle body facces up not to the passenger side of the car.......i need someone with some brain cells and experiance, and not magazine knowledge and 'BAD GROUNDING" problems

 

did it just start doing it one day
? or did it start after a modification? ive also heard of this from a leaking IM gasket. try checking that out too.

 

my car is still doin the idle jump but from 1500rpm to 1800rpm and it stops when i unplug a sensor, i can leave it unplugged but the car throws about 5 codes but when i plug it in again and restart the car guess what, same idle problem, i have unpluged on plug and messed with the screw and thought i had it fixed until i turned it off again and restarted it and it still had rpm rev.... im in the same boat waiting for a solution..
