so i got the car from my dad...it had a misfire only wen trying to accelerate hard like 2500rpms and up...so i got new spark plug wires and spark plugs.it ran excellent for a week...then started misfiring really bad stalling if i take my foot off the gas...so i had a friend plug it into a code reader...it said the iat sensor was bad...so i replaced the MAF sensor...made no difference...then it got even worse...stalling more often,12 mpg,and then a new problem if u accelerate hard again over 2000rpms the throttle seems to stay high for a long time...i tried cleanin the idle air control vavle,and replacing one of the oxygen sensors and cleaning the other one(didnt have enough money for 2)...still no difference i need help
