I have a 03 Gt auto and sometimes when i floor it it doesn't seem like it wants to go WOT either itll take a min then do it or it feels like its just in passing gear....idk what can be the problem any help is apreciated thnx.

 

well it could be ALOT of different things.
not enough fuel/air/spark.
any number of things could be causing it.

first things first. any codes?

 

nope no codes at all...it runs great besides that

 

if its not throwing a code it could be the mass air unit. try cleaning it with a parts cleaner. It could also be the throttle position sensor. but like the last post says there are multiple possibilities

 

it has a c&l mass air flow unit...i wonder if he ever had it dyno tuned for it...the car came with everything it has by the way

 

anyone else?
