I recently put a j32a2 into my 92 civic and finally got her started the engine runs great for about 3 minutes and then the idiling picks up and drops and so on is there any body that can give me some advise on this .

 

might be IAC valve

 

vacuum leak?

 

Bleed the cooling system. You probably have some air caught in the IACV causing the readings to be off.

You may need to adjust the IACV sensor too. Since this is a swap, youre not running the power steering or air conditioning, so its preconfigured to control idle with those loads on the engine. Dremel some slots into those screws, loosen it and twist the sensor a bit to adjust.

Are you throwing any codes?

 

im sure im throwing codes but since this a 92 civic it did not come with a computer plug so i cannot check any codes plus im running the power steering .has any body done a swap like this yes there are some wiring questions that i have.

 

Yea, theres quite a few people who have done this swap, but not on this forum. Id send you the links but you cant get pms yet.

 

please send me those links ive been busy with this project for a long time and i can use any help that i can get .thanks allot guys for helping me.

 

u say 3 minutes and then u get issues. That's when the car gets to temp and starts running in "closed loop" I think it is, which is when the car knows it's warm and then starts using all the sensors to determine a/f ratios and idle and so on.



So ur idle is probably at like 1000ish and then when she's warm it starts acting up? Insead of dropping, it becomes sparatic?

I had this issue and was the Idle air control valve.

 

Since you cant accept PMs, Ill just post is here.
