I have a 92 f250 4x4 5.8 It had been sitting four 2 years bought it had a tune up done new battery and brake lines and alternator it was running great. then out off no were running like crap, wont idle and sucking gas like crazy. so i put a MAP sensor in it and a fuel regulator both were bad still not running good, any help would be appreciated.

 

Running bad..Very wide open field. What exactly is it doing? I have a 94 with a 5.8. Running bad with poor mileage could be anything from a bad idle air sensor, to a bad ignition wire or, the timing being off from a worn distributor. Just a backyard mechanic but will help if I can. If you can be more specific, I will do what I can to help.

 

sorry for the lack of info, I was not using my head, the fuel regulator was bad so after I posted the message I checked the oil and it had almost a quart of gas in it. I changed the oil and plugs, and its running fine now. Sorry to waste everyone's time.
