Great to hear!

My poor cold idle has to do with the damn IAC valve also.

And I also need a midpipe, but only because I'm sick of the stock exhaust on this 165. lol.. need better exhaust so I can add this MBC i've got laying here.

If you do get a new midpipe, let me know because I'll buy your stock one...

okay I have to ask, but what is an IAC valve. I have just about all the abbreviations down, but I cant think of what this one is. My cool idle sucks lately, and I'd love to track down the culprit.

Idle Air Control Valve. It's the little bastard under the throttle body that's supposed to regulate air flow at idle.

Probably that or your cold start sensor. Or bad connections.

Idle Air Control Valve


is that the little bastard with the black plastic screw in it? The screw has a spring behind it? If so mine isnt under the TB, its more off to the side on the drivers side of the car. I've tried adjusting it, but it doesnt do squat

No. The ISC valve. It's attached to the throttle body.

Not the A/C idle up.

you should be able to blast air through the coolant lines on the IAC and that should clear up any problems with it. careful with pressure.

there are coolant lines running to the ISC valve.

I'm not sure if or how running pressure through the lines will fix the ISC valve if it's faulty. Bang on it, or get a new one.

Peace.

if the car sits a lot or has cruddy coolant in it or has some debris floating in the coolant 9 out of 10 that's where it'll clog. that's why you blast it out.
