i've been trying to go through the car recently to get it ready for spring and as it sat through the winter, everytime i would go to start it and let it warm up every week, it would refuse to stay running longer than 5-10 seconds. To solve this, I could just throw the scanner on it and erase all the adaptive memory and everything would be fine. That no longer works and realisticly, that isn't really the way I would like the car to operate. Just swapped out coolant temp. sensor, TPS, and IAC. Upon the first start up, everything functioned better than it ever has. Car runs and drives fine. Then it sat overnight with temps in low 40's. This morning, same old song & dance. No start again. I really don't know where to look other than possibly o2 sensor. Car is a 91 Spirit RT, all stock style electronics. I believe the o2 is about 2 years old, intake air temp sensor is new, and of course the others listed above. Any ideas?
