I am about to take my 2004 Chevy Malibu to the Shop Once again, but before going this time I want to know if anyone could help or may know whats the matter. My car starting acting up going up hills it wouldn't accelerate it would start to jerk an start to shut down. We took it to the shop an they changed the MAP sensor and on the way home it did it again..Then they Changed MAF an Throttle sensor? on the way home did it again. So we decided we would change all the plug an stuff on our own and it did it again. My husband ran the codes an they are showing up MAP an MAF sensors. Is there anything that would make those two keep going bad or setting those codes off?? I don't want to spend another 1,000 bucks and the problem not be fixed!
