Help!!

damn i know i write on here alot but ....now im loosing power almost by the day and i cant figure out whats wrong...no engine lights or anything...scanned the chip on my car and it says everything is fine...and i cant see any visible signs of a cause...im wondering if it could be something like a vacuum leak or something along those lines or maybe my fuel pump but i dont want to replace or get every single thing checked out cuz i dont have the time , money , and patience to do something like that....so if someone could help me out that would be awesome. thx

well the map sensor could be a problem. if there is a hole in the hose coming out of the map sensor you will have power loss. and will not get a Check Engine light. but other than the normal change plugs wires and oil and filter... then i would start with map sensors and vacuum leaks.

Maybe fuel injector cleaning at dealership too... air filter as well. THere is alot of pollen in the air this time of year.

Those plugs are crap... they do more harm than good, and totally defeat their intended purpose. Go and get the AC delco plats or NGK Iridium.

DITTO, This could very well be your problem.
