Engine Performance problem
1988 Other Mercedes Benz Models 6 cyl Two Wheel Drive Automatic 86000 miles
I have plenty of gauges, but how can I test the fuel pressure on my 1988 Mercedes 300TE. I have a misfire which I am trying to route down and after testing for vacuum leaks, replaced plugs+wires+distributor+rotor+cap+coil+fuel pressure regulator.I'm running out of ideas. Its not mounts and its just random sputtering.
Any help would be MUCH appreciated. I've been battling this misfire for almost 2 years now.
