Well I drive a 91 MRK Vii and it just recently started to sputter and miss. The plugs, cap, rotor, wires, and fuel filter were change about a year ago but I just cleaned the t/b, egr, egr spacer and ran a fuel injection machine on the car 2 weeks ago and its still running like :q:q:q:q. I really wish I could solve this problem because it's getting really annoying. Can anyone give me a clue as what to do next in my search to correct this problem.
