I am the "proud' owner of a 1990 F-150. This truck has left me high and dry 4 times in 18 months. Not counting the new engine and trans (the trans was my fault) I put in it. So far I have replaced the map sensor, o2 sensor, fuel pump relay, dist. module, and a pin in the steering colum. Alot of these things, I am told, are problems that Ford has. My question is what other problems do F-150's have that I might replace now before I get left high and dry again?
