Engine Performance problem
1993 Ford F150 V8 Two Wheel Drive Automatic 82000 miles
I have had this problem before and took it to a hack and it ran better for about 6 months, then it started again. I do not have the money to spend on someone who cant fix the problem correctly. See when I start my truck which has a 5.0 302 engine, it seems to run smooth. I rev it up in stages from 1000 rpm to 1500 to 2000 and so on and it runs smooth. I put it in gear holding the brake and putting it under a load while doing the same thing as before and it seems ok. Then it hits running temp. On a ford it is in the middle of the gauge, although I imagine its about 180 or so. Once it hits that it turns into a shaking knocking mess. I cant even get the rpms above idle and it struggles for what sounds like fuel, except for the 15 minutes it took to warm up it did not exibit any of these problems. If I try and give it the throttle it gets worse and seems like the thing shakes so bad the engine is going to rip off the mounts, plus it sounds as if it is deiseling or knocking really bad. I have put fresh fuel in it, I had tried to use a fuel additive in the past and nothing works. Both pumps run as I said until it gets to running temp. I cant drive it because I do not have a current licence on it and I also do not like chugging down the street. I do not have any code readers and cant afford them. I should not even be working on this thing but I have a back injury and need to go to the dorctor and cant afford the $120 trips. Is it something simple that I can fix in my own garage, a oxygen sensor, fuel pump, relay of some kind, Or should I save my money and take it to a shop that wont screw me over. I even checked the emergency fuel shut off and it was not activated so I am stuck. I was a trained tech, in a college course but that was back in 1990 and most of the cars we worked on were not loaded with all this computer crap. So My knowledge only goes as far as do things I know will not mess up the computer, basic diagnosic. I really need help. I have a place to take it but if I can do it with out spending the money I do not have That would be great. It also sounds like when it is warmed up that it is sucking in alot of air rather than fuel. Don't know if that would help but thats it. Can you help. Thanks so much. Tim
