Re: Engine light on and runs rough

Well I think it's fixed. The engine light went out last night. One of the tell tale sign for me was the driver side plugs were all black and the passenger side were all nice white. So that told me that a fuel injector nozzle most likely wasn't it. It was something common with all plugs on 1 side. With engine running have you sprayed carb cleaner or something similar around all intake ports? If engine changes the way it runs then you have found the vacuum leak. If all is good then I would pull plugs and look at them. You will be able a lot from the plugs if something is wrong. If only 1 plug is bad looking then it is something isolated to that cylinder. Hope this helps! Keep me posted and we'll get it!
