an01sts Posted June 25, 2005 Report Share Posted June 25, 2005 My car is stalling. About a week ago, I noticed that the car seemed just a tad sluggish. I installed a new air filter, but when I pulled the old one, it seemed obvious that it wouldn't make a difference. When the car is first started, it has a mis/runs rough, and slight tap of the accelerator pedal smooths it out. (It also stays on high idle longer than usual.) If I'm poking along whithout the tranny shifting up, it runs smooth. The problem happens when the cars gets up to speed and into the higher gears. When you let off the gas, when the tach droppes to around 2k, the tach drops instantly to zero. Then it flutters around between zero and 1.1k to 1.3k, always ending up stalling. The car also bucks as it drops into first gear. When slowing down, if I give it just a tad of gas, it doesn't stall. Pull codes! I know! How do you pull codes on an 01 STS?

JIMDTS Posted June 25, 2005 Report Share Posted June 25, 2005 It almost sounds like you have a bad crank sensor I had the problem of stalling and that took care of it. On the 01 i have while idleing it would just stall never happened again after the sensor change and it did not throw any codes Jim Link to comment Share on other sites More sharing options...
JimD Posted June 25, 2005 Report Share Posted June 25, 2005 .... Pull codes! I know! How do you pull codes on an 01 STS? This file provides more than you ever wanted to know about retrieving the codes for your model. An occasional misfire might or might not set a DTC. Sounds like crankshaft position sensor(s) to me.

an01sts Posted June 26, 2005 Author Report Share Posted June 26, 2005 Thanks folks. I had the crank sensor(s) replaced around 30 to 40k. It also has the service engine soon light on, which came on shortly after the problem started. If it showed up as a code, it's a safe bet to say that it would be PCM?
