I checked the check engine light, and now it says my MAP sensor. Well i changed it with a new one, and it still says MAP sensor. I dont know what else to do. Now when i rev the car to around 4000rpm, the car wont go any further, and i lost a lot of power. But when the check engine light went off the car didnt stop at 4000rpm. Its back on and i'd like to know what the hell is going on.. thankx

 

If I were someone that hadn't read through a lot of other threads in this section, my first question would be what kind of car, what year, and what motor? Those are things you should ALWAYS include in your posts when asking for help

Are you still having the problems you described in your other post in this forum?

What is the code you get? What #?
