Was just given a 1994 Grand Cherokee. V8 5.2 engine.
I live in the northeast so the outside temp dips down to zero overnight.
I went to use it the other AM after a zero degree night. It fired right up, but when I shifted into drive, nothing. It behaved as it was in neutral.
I discovered that after about 20 minutes of idling it works again. I dont make a habit of driving a vehicle ice cold, but this seems really weird to me. Especially the 20 minute wait. If there was a piece of electronics that doesnt let one drive the thing untill it's warmed up that would make sense, but that would account for five minutes not twenty.
Any Insight?
