Hi!
'01 Viggen, 90k miles, battery <1 yr old, drives fantastic, no hesitating or CEL, makes full boost, OEM DI cassette ~3 yrs, spark plugs <1 yr and < 3k miles. No issues starting when warm. When cold, (right around freezing), the car has become hesitant to start. Cranks fine, plenty of energy. It catches then stalls. This AM it wouldn't catch until my 5th try, then stalled. Sixth try and it fired up, running a little lumpy for the 1st second or so and settled in after that, running very well. Coming back from errand, still warm engine, it fired right up.
I've experienced CPS (camshaft position sensor) failure on other 2 other Saabs (9-5 Aeros), but those seemed to happen hot/cold outside temp and hot/cold engine temp, which is why I was doubting this could be the case with my Viggen...
Any ideas? Appreciate your inputs!
Best,
Rick
