Recently in the cold my car likes to stall in reverse. As soon as i shift into R (auto Transmission) it completely shuts off the dummy lights come on. Then i have to put it into park and start it again and it works fine. Any ideas what could be causing this im pretty sure that the tranny is perfect. I have a stage 2 Valvebody from jeff at maximum tuning. I also have a geforce ecu. The shifts are perfect and show no signs of sliping. I have the egr code 0302. Im not sure if this would cause the problem im having.

 

Dirty IACV or sticking IACV solenoids most likely... shifting into R puts an extra load on the tranny - the IACV should compensate for that, but it isn't able to.

 

it shifts it pretty hard into R too ive noticed. So just replace teh whole iacv ? Ive cleaned it before but its got 170k on it.

 

No CEL codes right? Sounds like a bad drop resistor...(the hard shfiting)

 

nope no CELS except 0302 the egr valve. Are bad drop resistors found often in our cars ? THats the thing found on the driver side strut tower right.

 

No - not what I would consider a common problem, and Yes on the location.

 

Oh, I'm also not sure if a clogged EGR passage (which is why you have 0302 most likely) would cause an idling problem... it may... I'll need to look into how/when the EGR valve is supposed to open up.

 

ive replaced the solenoid twice and still no luck so i guess i have no choice but to remove the intake manifold hehe. It is actually a weird proble, at stops sometimes the idle raises to about 900 and stays steady their untill i come to another complete stop. Sometimes it constantly stays on 900.

 

The EGR problem is clogged passages...

The idle problem is sounding more and more like a sticking IACV/solenoids in the IACV. Just pull it all apart and clean it... (intake cleaner or whatever)

 

what is their to remove on it besides the gold plate ?

 

You can remove each solenoid from the other side and clean out the plungers...

 

oh reaalllly i did not know that sir. Is their a guide ?

 

Remove screws, clean out.

/End of Guide

Just kidding.. no guide that I know off, but I can take a peek tomorrow (I have a spare one in the garage that I'm too lazy to go get).

Just shoot me a PM to remind me.

 

is their a screw like fitment on the plastic part of the iacv under neath that gold plate ?

 

No - don't mess with anything on that side except removing that brass (or whatever) hat and cleaning all that out.

There are a few screws on the other side with all the connectors that you can pull and clean.
