My check engine light comes on every so often. I've had it on the scanner and it says that cylinder 1 and cylinder 2 is running lean. WHat could cause that? I run midgrade and i tried premium gas but still does the same thing. I dont know what it could be. Any suggestions?
Actually its say bank#1 and bank#2 not cylinders. All you have to do is turn the fuel pressure up 2-3psi and reset codes. If you don't have an adjustable fuel pressure regulator your car is telling you to buy one now.
