Winter is over got my car out. gota fix some smal probs)

Yup, I got my car out of storage yesterday (yeah :smokin:)

I still have a few things to fix but I'm really happy.

When I start the car in the morning, it idles like a V8 is under there. The Idle is low and lumpy. I DO have a JG Engine Dynamics Camshaft but I don't think it's the problem. when the car warms up it's all fine.

Last year I already checked the temp sensor and it's not the problem. I'll have to check if it runs on 3 cyls (when cold) but I don't think it's the case. (I'll check the compression too)

Could it be the BOSCH O2 sensor that need some time to heat up??

Fast idle Valve that sucks??

A vacuum leak would make it idle higher than normal I think.

Any input appreciated.

no, if i remember correctly you have B20 right?
O2 sensors don't need to be warm. they should work at any temperature.
yeah i think you are right. vacuum leak will make it idle fast on EFi.

nah I don't have the B20A in yet. it's still the plain Old A20 :)

I'm unsure if your engine has EGR, but if it does check to see if you're getting EGR at idle. There could be some build up on the pintle of the EGR causing it not to seat fully. Just a thought.

The cam will be for sale when I swap the B20 in :)

Good idea about the EGR :) I'll check that too.
