Okay, I had to do a timing chain overhaul on my the car. The guy that did it seemed to have done the internal part correct but at the end just slapped it back together. I have gone through it and tightened nuts and replaced sensors and just trying to get it in safe running condition because it is all I have. So It runs pretty good but Obdi says it’s running too lean. I cleaned the fuel filter and it seems to be better but it just shuts off sometimes. I have not been able to drive a full drive cycle yet. My dad says that I need to have a computer fine tune the computer to dial in the new repair. Is there a way I can reset it at home because I don’t have a lot of money to get ripped off by a mechanic in my town? Especially because I’m a girl and that’s how it works in this town.

Hello,
If you want to reset your Power-train Control Module(PCM), Ford calls it Electronic Control Unit(ECU), a.K.A. The "computer" on your vehicle, simply take the negative battery cable of the battery for at least five (5) minutes. This will completely erase the vehicles Keep Alive Memory (KAM). However, you should record any Direct Trouble Codes (DTC)'s a.K.A. "codes" before you do. All information will be lost. It is the equivalent of doing a factory reset on your cell phone. I have included an informative diagram below.

Thanks,
Alex

I replaced the fuel filter and cleaned the throttle body and now it surges again but it has not died at all.

Hello again,

This could be a timing issue. Can you double check that the timing is correct. I have included in the diagrams down below the procedure for removal, installation, and timing mark alignment. Please double check and get back to us with what you find out.

Thanks,
Alex
