In my case, the car (1993 Aero) was triggering a whole series of different Check Engine Lights - all of which went away for days, weeks or months if you disconnected the battery for an appropriate length time according to the CEL - but which were never permanently repaired by replacing the suggested failure part. As it turned out - it was a very slightly bent loom connector to the firewall Safety Valve beside the MAP sensor - a sensor that was replaced a couple of times. In my case that meant that every time a Tech would check the resistance on the Safety Valve (it should be very close to 30 ohms) and put the connector back together - it would run fine for about a week - then fail again for no apparent reason. Given you have been to the dealer and assuming they have properly checked the safety valve and vacuum lines for correct parameters instead of just plugging in the scanner - I would start looking over the loom for suspect connections that feed the engine management computer(s). It may well be that there is a problem with your Throttle Body or TCS system - but I now think that should really be the last stop in a rather longest trip through the wiring loom given my (and the previous owners) experience. -- Radio Free Dexterdyne Top Tune o'be-do-da-day Patio Lanterns - Kim Mitchell all tunes - no cookies no subscription no weather no ads no news no phone in no sign up required - all the Time
