I have a 1993 5.0 mustang. I just bought this car and have no history on it. My problem is this. The car has some type on aftermarket cam and doesn?t want to idle. I replaced the spark plugs because they were fouled out ( covered with oil) After replacing the plugs the car would start but still ran rough and after a few attenpts to do some repair the plugs have fouled again. the engine has about 132,000 miles on it. I ttok it to a repair shop and they recommended I try and put a stock cam back in it. I was also told that the fuel pressure regulator may be causing some of my erractic idle / fouled plug issues. The mechanic that looked at it for me said that the timing was set correctly and the compresion was also ok.
Please advise.
