subject, '87 Vanagon all stock, 79K miles (yes that's all)
symptoms, hesitation, VERY doggish until warmed up. When up to temp it runs
OK but feels down on power. motor doesn't seem to rev as freely as it did.
Just plain runs like a dog.
What's been done: new O2 sensor, head job, (was leaking coolant), new water
pump & coolant. New plugs. Wires, cap & rotor less than 10k miles old (all
Bosch). Used cleaner on mass air sensor. Am running 4x super-zoot
injector/carb cleaner through in current tank of gas. Plugs I took out were
clean on one side, showing cleaner stuff was doing it's job, & all injectors
are squirting. New gas filter. Had cat converter checked. Timing spot on.
Torn out hair I can't afford to loose .
So, which sensor is sending bogus info to the digifant?
