Recently I installed an AEM cold air intake and Borla exhaust. Since then I have been noticing that when I accelerate in third gear the car hesitates and loses power between 2000-3000 rpm, after 3000 rpm it will accelerate again. It is only in 3rd gear. I just had the transmission rebuilt because my synchro was bad and the hesitation is still occurring.

Fuel and spark are the most common. Plugs, wires, fuel filters...ect...You should start at the beginning.Was it working fine before the intake install?If yes, something got screwed up during the install.Check your plug wires to make sure there tight..ect. How are the spark plugs? Have you messed with anything else? Any check engine codes?

If it does, I have heard that vacuum leaks from the CAI install, can cause these kind of problems to! Go over the CAI and make sure everything is secure, example: clamps, tubes, etc... Good luck man!
