Engine Performance problem
1994 Volvo 940 4 cyl Two Wheel Drive Automatic 191000 miles
After sitting all night, cranks long and studders, as if miss-firing, burns small puff of blue oil smoke, in 10 to 15 seconds cleans out and runs normal. Will start OK unless it sits for many hours.
runs fantastically, full of power with turbo, ho oil burn, oil changed every 3k miles, 191k miles well maintained.
Volvo checked fuel delivery, pressure, and changed the fuel pump and injector relays. Changed the rotor, cap, wires and platinum plugs.
Volvo thinks it is oil fouling the plugs due to valve stem seal and stem wear. I do not.
It appears to be injector related or idle-to-start-up injector related.
what do you think, please
have the same problem?
