Ok, so...I got the codes pulled, and i need to know exactly what can happen when when these sensors go

1: Throttle positioning sensor
2: Engine coolant sensor (i was told it is not the same sensor as shows on the comp display)
3: Tranny oil temp sensor

Please a little help. Could the TPS be the problem with the 2500rpm idle?

when your tps sensor goes, you will have surging or non existant idle. I have a problem with mine in my "mustang", and it causes surging idle up to 2k rpm. A bitch of a problem.

How much would it be to get a new one?

on the mustangs it's not an expensive part, i haven't priced them for a mark tho.
