Okay i have a 2002 wrx. its an automatic (i know lame) and i have about 117,000miles on it. i have added some aftermarket parts but im have a problem with the throttle. today when driving at about 70 to 75 i floored it and it started acting like it was getting power and then not. like a wavy acceleration. its hard to explain....kind of like i was geting power, no power, power, no power, power, no power. it has done this before to just wondering what you guys might think it is. i have not got a tune yet and i think that might fix it but wana know what you think. this is what i have added on my car performance wise. new 3" turbo back exhaust, un-equal length headers, up pipe, perrin lightend crank pulley, aem short ram intake.
also from a stop if i floor it some times when it shifts into 2nd the car feels like it looses all power and almost dies and the at oil temp light starts to flash?
