losing power

i went to the track yest and couldnt break 14s when i was running low 14s in fall. I had the car stored over winter and put in a new alternator and have been drivin it for about a month. I have been noticing under full throttle i can feel the car losin power and not running good. It makes a faster puttering noise and bogs down very bad at wot. This drastically hurt my times. Any ideas on how to fix this would be great thanks

RE: losing power

Clean the MAF, IAC, and the EGR. Then set the TPS and that should fix your problem

RE: losing power

I'd check your BAP sensor too. From sitting it could have gotten some moisture in it and it can make your car run too rich. That's what just happened to my car except it's the MAP sensor, same sensor different name, and was reading too high for the desired vacuum making it run real rich.

You may also want to check the spark plugs and see if any are worn or discolored more than the others. That will tell you if there is a misfire due to a dud plug. Then you can replace the wire(s) associated with the plug (s) and clean/replace the bad plug if needed.
