Thread: Sick car

hey guys. I've tried just about everything but I still have a VE that is just not running up to par. just changed the plugs, cap and rotor. Car runs fairly rich, especially if it sits for a few days. I think i have a bad IACV. using a JWT ECU with a MAXIMA mAF 95-99.

any ideas?

I have an IACV if you want to try that in my 2.0VE parts listing...and I assume you've had this VE running good before?

isn't jwt always a little on the rich side?

it does but it seems to be more than "normal" for jwt... The car has never run "perfect" but it seems to be getting worse..

bad 02 sensor? timing? knock sensor? I'm just throwing things out there.

Try a new thermostat.

Mine ran rich constantly due to bad O2 sensor recently...if you haven't tried that...might be a good start.

going to try both... I can just get them for a regular DE right?

Yes.

how does a thermostat cause a car to run rich?
