Im having a bit of a problem keeping the car at idle. The car drops to around 500 rpm and fluctuates or just dies when Im coming up to a stop light. I was thinking a vacume leak but all of the hoses I know of are ok aswell as the connections. I heard it could be a dirty maf or a leak from the cold air up to the sc. any ideas? A buddy of mine said something like using a little throttle body cleaner and that may do it since there are sensors in or close to the tb. Im running a KB supercharger. It also throws a CEL every once in a blue moon. It started two weeks ago when I went to DC from del.
Thanks
Matt

it said no info available. I believe I found the source. The air filter fell off. I found it nestled up in the bumper I cleaned it up and put it back on and no problem so far. the car has a good idle and does not die when I pull up to a stop light. The rpm drops to 500 and goes right back to 960 (what I have it set at). so hopefully that solved it

Ya that happened to me about 3 months ago and my cold air intake was loose and once i fixed that I re installed my tune and it straightened right out.

Back in the old days, if you sprayed carb cleaner around vacuum hoses or the manifold, but kept it away from the airfilter, a slight up tick in rpm would indicate a vac leak. It will do the same on fuel injected car.
