Oldsmobile/Buick Repair: hesitation after warm up, coolant temperature sensor, throttle position sensor


Question
1995 olds cutless supreme SL after warm up my car would not take off after i came to a stop.it would not even pull a hill it had no power after a stop, it took a while to get going, then i changed the wires and plugs this worked good for 2 days, now it's doing the same thing after warm up no power when i come to a stop.

Answer
Hello Joe,
Your statement, hesitation after warm up, indicates to me that it runs fine while cold?
That would seem to mean that while sensor inputs are not used, (open loop), that no restriction in the fuel system,(pressure, filter, etc.), exists.
Therefore, it would seem to be a computer controlled problem, probably from faulty signals from a sensor.
Some of those could be coolant temperature sensor, Throttle position sensor, Oxygen sensor, crankshaft position sensor, etc.

Here is an interesting description of coolant temp sensor problems, and specs, as well as some info on the TPS.

You can also go to Autozone, and have the fault codes read, to see if any exist.
