Help Has anyone here had trouble with their MAF sensor? I have been experiecing eratic power loss and my car runs rich when its warm outside. I replaced the O2 sensor just a while ago, and besides it doesnt seem like that would be the cause, because of the eraticness of the symtoms. Sometimes I hit the gas and my car feels very powerful, and then five minutes later I can hit the gas and it feels like I lost 20hp, wtf? I checked the computer codes, and everything seems fine, but I know its not. Has anyone had a similar problem?
