i put a h22 turbo swap into my 93 hatch. everything is work great, my ecu is tune and everything. But, for some strange reason when i gave it a hard test run the car only goes up to 4500rpm and when it reach 4500rpm it feel like the car start to lose power and start bobbling. it still redline but just that once it reach 4500rpm the car bobble. people say that it might be my TPS sensor because i did put another one in, and they say to recalibrate it using a multimeter HOW? by the way, check engine light is on too. i'm thinking it might be the trottle body and tps sensor but i'm not sure. please help. thanks
