With everyone's help here I got my project car running great (miswired MAP sensor.) Many people guessed my drivability problem was my missing EGR valve in the IM, which leads to my question. When I read engine codes, it did NOT show the EGR as having a problem - why? I know it's code #12... Could it be that it'll come on at a later time after driving a while?

The engine is a 95 H22A1 with stock P13 ECU.

 

well its not and instant code thats for sure ....i used to get it on big hills when the car is under more load than normal ..or any time i went abouve 80kmh

mabye yours isnt heavy enough to register as being under more load than normal ??

mine would come on after about 10 mins of driving. that was w/just the vacume line pulled, egr still pluged in.

 

Yeah okay... that's what I suspected. So I might still have a drivability issue but I just haven't "provoked" it yet.

Thanks for the input.

 

yah, i took mine out and i actually drove 15 miles before the code popped up.

 

Error code aside, how was your drivability without it?

 

Good question!

 

mine still kicked it, jsut a little slower. kind of like it retarted the timing a little bit.

 

Okay... looks like I really should put it back in. Hopefully the member here who said he'd send me the parts does so...
