so i got it running yesterday and it smells like its running rich and i got a cel i got the code for the iacv its surging from 1400 to 1700 it only does it when i am in neutral when i get it in gear it runs not good but it runs. I havent been running it at all cause i want to get the cel fixed i am getting some more codes i am just wondering if the iacv will make more codes go off and what could make it surge like that?

if you're running it on a stock P28 it will run rich and the IACV will make it surge like that if it's bad, the FITV will also make it surge if the nylon washer inside is loose.

why would a p28 make it run rich?

why would a p28 make it run rich?

different fuel map from the P08. 1.6 vs 1.5. When I had my P28 unmodified it would take forever to warm up in the mornings from running so rich. running in limp mode I'd suspect it would run even richer due to the o2 not compensating.

yeah the guy i bought the car from said he chipped it out it had a d16z6 in the car well the motor fuked up so i put the d15 in it do you know how to chip it out?

 

[NeonPinHead]

Yeah, I chipped mine and burned a stock P08 map on it and it runs much better now.

 

[sik_civik]

how do you do it? am i going to need a sodering gun?

Here's a Link to my DIY ECU chipping Thread.

probably a stupid question but what happen if i left it alone without chipping

 

[NeonPinHead]

nothing a stock P28 ecu will run it just fine I had mine running like that for a year. It just runs rich, which will waste gas so in my opinion it's worth the price in gas just to chip it.

just one more ? my iavc i cleaned it today and its still good but my cel keeps going off and my car keeps throughing out that code out. On the two connectors on the bottem of it do i plug the one on the right do you think it will fix it?

 

[sik_civik]

the reason i ask is on one of the connectors its to a coolant line i think not sure thats what my friend told me and he helped me with the swap so should the iacv have the coolant going into it cause that goes into my intake manifold.So should it be there or should i change them
