Had exact same problems with my '99 Cadillac Escalade recently, but I would also get a check engine light at times. Turned out a few of my fuel injectors were clogged. Dealer cleaned them with high pressure solution and problem solved.

'99 740iL

Hi again ya'll,
Got a problem with my 1997 740i running very ruff after it cranks up first thing in the morning. The last couple of mornings have been "cool" as in the low fifties and the engine kind-of almost stalls...dies...stumbles, then runs very ruff. If I give the engine some gas it really stutters, I have to "pat" the throttle until the RPMs get above 1000. The engine has never 'died' but with out the patting of the throttle it doesn't move the car forward. After the Temperature needle gets above the blue 'hash' mark the engine smooths out a little and when the engine is at operating temperature it runs just great. If this engine had a carbartor I'd say that the choke is messed up, because it's injected is there a 'cold start' injector or pulg or something that isn't working right?
Any thoughts?
C'ya,
Patrick
