2004 Grand Prix 3.8
So after traveling 3 hours I was pulling into a street and the car start hesitating really bad and idling really rough, I lost throttle response and I got a “Engine reduce power” message.
I scanned it and got a code for the MAS sensor and one more for “Throttle Correlation”.
I did found the MAS sensor broken, I replaced it that took care of the first code; I checked the throttle flap and it does move when I flip the key. I checked my injectors and I found that 1, 3 & 5 injectors don’t work; I checked the fuses and they seemed to be ok. I’m trying to get some advice about this before I buy a throttle body.
