Well, recently I had a low idle / idle stall problem which ended up with the car stalling each time I came to a stop. I spent one week desperately trying to figure out what the problem might be; had read all the available posts, and tried every combination (new filter, etc.) to find a solution...
There seemed to be many possible reasons causing low idle or idle stall. I noticed that many jetters (at least more than I anticipated) had that problem and a considerable amount had it after CAI installation...
I went to the dealer (a friend) only to find out that the problem was ridiculous, and the solution was "siller"...
The problem was at the idle control valve (that is at a jerky place, and hard to reach) which was blocked by the car's very own "protective" coating of the inner throttle body...(and MAF sensor walls as far as I know)
The protective coating (classified as "don't remove, don't even touch") accumulated at the valve, causing it to malfunction. Hence came raugh idle and stalls...A quick cleaning of the valve with a degreaser spray cured all...The car started to run flawlessly...
So, I believe the drainage and accumulation of the protective grease is caused by the much higher air flow (which is a good way to explain why people have this problem after CAI installation) and despite common belief, at least the TB coating should be cleaned off when installing high flow intakes...
Hope this helps some people out there...Any comments are wellcome...
