Problem with my 95 F150 4x4 with 5.8 winsor
I'm having a problem with my truck. its a 1995 ford f150 4x4 with a 5.8 v8 and i think its a 351 winsor. i dont know a hole lot about trucks so i need some help on this one. i have replaced the battery, altenator, serpantine belt, starter, oil pump, egr valve and censer. i have also recently changed my oil, oil filter, fuel filter, ail filter, and spark plugs. and i am STILL having a problem. the problem started when i was drivin and i noticed my truck started to sound like it was about to cut off. i didnt think anything of it because it was at a red light. a few days later it started again but it began to shake the entire cab at 28mps+. i changed the egr valve and the egr censer (recomended i did after he ran codes) it ran good for about a month. but it started again. but now it only shakes at 30mps+ (if you floor it, it stops) but the twist is when im going over 30mps and it starts shaking, if i turn on my hazard lights, it stops shaking and runs great. i got everyone i have talked to about this completly stumpped. even a certified machanic. last time it had codes ran on it after this started shaking this last time it says imcomplete circuit or something like that, and an unknown code. i cant see any wires damaged but there are alot of them. anyone ever ran into the same problem before? maybe you can help. keep in mind that autozone, napa, and advanced auto parts computers all say that my year make and model doesnt have a knock censer according to them. but they may be wrong. PLEASE HELP

You're going to have to get it looked at by a dealer. They may argue the point, but aftermarket scanners DO NOT have all the data necessary for proper diagnosis (they purchase the right to use the data from all of the manufacturers, NONE release all of the data).
