I did what you said I check all fuse vacuum lines I got it down to the MAF sensor I unplug it and it ran like was before this started. Will it hurt my engine if I keep it unplugged? Thank you so much for your help.

I put a new one on last month it seemed to run worst than it did, but it starts on a third try now. The sensor to the left of it shows to not have power but when I unplug it I get a click in back of the motor, the same as putting it back on. I know it is something simple I just cannot find it. Thank you, BENJAMIN

It sounds like you have a bad ground wire, can you go over the wiring harnesses to check that the grounds are clean and tight?

Please let us know what you find.
