Hello there. (1) I have 2004 awd Pontiac vibe with 204,000 miles. Recently, I have all the 4 cylinders misfire. So I replaced the throttle body, vvt solenoid , cam sensor, plugs and the coils. All those couldn’t help. The timing might have screwed up but not sure yet
(2) I just bought 2007 fwd Pontiac vibe 140,000 miles and has P0452 code (Fuel Tank Pressure Sensor). I don’t want to start replace parts until I’m sure of the problem. Can anyone help me please? Any help will be highly appreciated. Thanks
