ok so here's my problem with the 99gt.

if from a stop, i accelerate normally the car will roll through the gears nicely with no issues to whatever speed i want including highway speeds.

however, at any speed, if i step on the gas ie to pass someone whether its doing 60km or 100km, i have a huge power issue. the rpms rev to where they should, but the car lags big time. almost like it's wanting to go but cant. i can let of the gas and resume accelerating normally with no issues.

recently changed the air filter and cleaned maf.

any other ideas as to where to start?

thanks in advance
