1995 Cav 2.2 5spd 180,000km
Intermittent 'chugging'. Usually the car is fine for about 2-5 minutes
after a cold start, then starts chugging for the rest of the drive.
Almost feels like someone is depressing the accelerator pedal and
releasing quickly when accelerating. When maintaining speed it still
chugs and feels like it is missing. When coasting down it smooths out.
Also sounds rough at idle.
It is not a clutch problem as clutch seems to work fine, no slipping
(under hard acceleration before chugging starts).
I've changed the plugs, replaced the fuel filter, and even tried
unplugging the EGR vacuum hose (someone suggested this tactic once)
Been thru several tanks of gas, and injector cleaner.
I'd certainly appreciate ANY help you could give me as it is a pain in
the ass driving down the road like this (and probably looks funny too!)
