How many miles are on this vehicle? Has it had a rough life? If you have low compression it is something mechanical...I would do a leak down test and listen at the air intake,exhast, oil fill neck and radiator... That will def. narrow things down... The cam sensor has to do with fuel timing plus is a sensor (electrical).. low compression (mechanical)...

hey what type of gas did you put in your car cause when you are running stage 2 map from cobb you should only use 91 octane or higher prefferably 93 octane
