This weekend I changed out my intercooler with one of those autobahn 88 kits. My factory one had a huge leak that I discovered whist trying to find some missing boost.
However when I took the car for a test drive I had a rather unpleasant experience with the car seemingly stuck at 3500rpm. Basically I drove off and as the car was cold kept the rpm pretty low. Probably no higher than 2500. After I while I decided to give it a bit more, and to my shock when I removed my foot from the throttle the RPM didnt drop. I turned the engine off and rolled off to the side of the road. I checked the throttle cable and it wasnt stuck or anything. Upon restarting the engine reved up straight away. I switched it off and had a further look around under the bonnet. I found nothing out of place (Im not a mechanic though) So I started it up again and it all seemed fine. I reved it up and down a few times and no problems. No problems on the way home no matter how hard I reved it and no problems on a subsequent test drive.
I was hope some folks on here may be able to point me in the right direction as to what may have caused this. Id like to investigate it further for obvious reasons.
To make matters worse the new intercooler and piping didn't find the missing boost, It did make the car more responsive and come on boost earlier but still only 5-6psi
