I bought a 93 Cobra last year and it ran fine with the exception of a little miss which I figured was because of the #3 wire melting on the header. Fixed that problem and put new plugs in it. Had to put a catted x pipe on it for inspection and it ran fine then also for the first couple of days. After that I started getting a constant miss. Replaced wires, again, plugs, cap, rotor, coil, and fuel filter. I noticed a little oil on rear plugs(3,4,8). Is this bad? I don't like it. Also, the upper and lower intakes were covered in oil although the pcv looks fine. Have I been had or what and can I fix this problem? The car is beautiful but does not run the greatest now and it's embarrassing. :(
