I have a 88 little v6 maro. I have a strange question about my crazy little six. When I start my car after the car has been sitting for a few days or has fully cooled down after driving the weirdest thing happens, the car actually moves very quickly. The car can spin tires and accelerates very quickly. But once the car starts heating up(about 300 sec after I started it) starts to run like pooh. The car always drives and accels bad, but I don't know why it is so quick when it first starts. I have a feeling that the cold thick oil is playing a part in this, but I have no clue what I'm talking about. Can someone clue me into what my cars problem?

 

well if you have no clue what you're talking about i sure don't either.

i'd gues s the oil has nothing to do with it, maybe more a case of good cold air getting sucked into the engine.

 

PT4200,

Your symptoms might be related to temperature. It is possible that the engine is so loose that the colder, more viscous oil is helping to seal badly worn rings, allowing more power production. Then again, if you are performing burnouts before fully warming up the engine and drivetrrain, there is little question that the rings are preobably shot, and everything else if not far behind.

Another possibility is that the cold engine is in open loop mode, and once it warms a bit and goes to closed loop, your fuel calculations are way off due to a failing O² sensor. Have you changed it within the last 30,000 miles?
