power loss and engine rumble?
 

my car has been stored in a garage for this winter so far and i went out to start it up today and it needed a battery boost and it started right up. now i gave it a little gas and revved it up good and high after warming it up for a bit. when i pressed the gas pedal in slowly and smoothly it ran great. now when i stepped the pedal quickly down to the mat it bogged out and when it hit about 5000rpm it went smooth again.

the ignition coils are brand new. any other suggestions or help would be great. thanks

engine is not warm enough, the ecu is keeping you from doing something stupid. which is what you are doing by reving a cold, or just warm engine.

this info is available in your owners manual.. please take the time to read it..

If your car is at proper operating temps to go wot, your ports may simply be alittle sticky,too. Less likely, but possible.

hrmmm well i let the heat gauge rise to it's normal spot before i began to rev it up. is that still a bad thing?
