Was driving my 91 RS the other day and it died on me. Coasted off the road and set for about a minute. Restarted the car. It started and drove about another 50 yards and died again. Won't start now at all. Turns over fine. Checked the ECm and am getting bad TPS and bad Oxygen Sensor. Are those 2 things alone enough to cause it to not start up? Going to replace them today as I know it's been about 2 years since I last replaced the O2 sensor. Never have replaced the TPS.

Any thoughts/suggestions really appreciated.

Thanks,
Tim

 

Is this a TBI or TPI engine?

Error codes for "bad" sensors? Exactly which codes did you retrieve?

A TPI will run (albeit poorly) with no TPS connected. I'm not sure what a TBI would do, but I suspect it would at least runas well. Make sure the TPS is connected, has a 5.0V reference voltage across the outer terminals, and presents at least 0.6V in the idle position (I believe your's is non-adjustable).
