Replaced the tps in my 1993 concorde and it dies when in park. Before it dies it sputters and almost dies then catches itself repeatedly. I ran codes and it said I had low or high voltage to tps and I was missing on more than one cylinder

Re: car keeps dieing
These cars are bad about plug wires. You need to find out what the voltage is on your tps. There is a test you can run on the tps if you have a volt ohm meter. Sounds like you need a good major tune up, which includes plugs, wires, clean the throttle bodies.

It could be a combination of 2 things. A faulty MAP sensor itself or a bad TPS (throttle position sensor). It's not uncommon for a bad TPS to idle when the motor is cold but once warm, not idle fast enough to keep the vehicle running.
Try exchanging the MAP sensor from the other "good running" car. What I think you are experiencing is a flat MAP which fails to read more than the minimum. A MAP sensor out on these cars will make it run absolutely terrible and die as you have indicated.
By unplugging the TPS sensor you are effectively putting the car in "limp" mode. In this mode it ignores a potentially bad TPS, O2, and MAP sensors and or circuits.
you could have a faulty Tps(throttle position sensor) this is located on the throttle body and has either a 4 wire plug or a 2 wire plug. I'm willing to bet that you need to replace this. the tps is responsible for your idle setting via the ecm(engine control moduel)...please rate this
Check to see if you have a lot of dirt in the throttle body. Clean the throttle blades out with brake cleaner or throttle body cleaner. You'll see alot of dirt come out. Keep spraying until it comes out fairly clear and wipe the throttle body out with a rag. If this doesn't do it, you may have a problem with the throttle position sensor (TPS). This sensor controls the idle after the car warms up and keeps it from dying when you brake or sit at idle.
