long tubed CAI?

if so your bottom end gets raped, I sometimes have that problem and I attribute it to the car not receiving enough air during idle with the lag time it has to wait for fresh air from a long-tube CAI.

remember when you add a long-tubed CAI, it lengthens the time it takes for the air to get to the motor than a short ram, the distance is greater and the car is not used to it.

but if you have a short-ram, ignore the top. Really if your car is having a rough idle at a cold start, then runs fine when warmed up, sit there and warm it up for a bit! When I am warming up mine I let it sit for 15 seconds, back out of my driveway, start driving, but keep the car at 2,000RPM in 2nd gear until the end of my street (semi-long) and then its warmed up without having to sit and wait in the freezing cold.

but others warming strategies are different...

I had this feeling HARDCORE one day where it starting bucking and finally stalled out, then I turn the car back on and it runs like a champ..


must just be FORD syndrome.
