ugh stalling rough idle codes 15&22 this car hates me

i have a 1992 oldsmobile eighty eight royale vin L engine.
i tested the throttle position sensor out and it tested out good .38 at idle 4.86 at wot (wide open throttle) but im getting a code 22 and have barley any power. Also i changed my coolant temp sensor underneeth the throttle body today and im now getting a code 15. plus the car is still jerking and stalling. so i have no idea what the hell is going on my car hates me.


if anyone could help this would be greatly appriciated considering i have school tomarow and this is my only car to get there with.

You either eeplaced the wrong coolant temp sensor, should have a 2 wire connector or the wiring is bad, this will cause the engine to load and run rich after warming up, the tps setting is low should be around .50

well the coolant temp sensor is fine its brand new matched up perfectly to the old one and the wiring is fine but i dont know why its poping up a code now also the tps should i just replace it? and could my computer be bad??

Get a scanner on it and see what the temp sensor reads. Disconnect and see what it read to confirm wiring.

temp sensor and tps tested fine im going towards the ignition control modual or the computer

replaced ignition control module today still having the same problem tps code and coolant temp sensor code they both tested fine so i have no idea whats going on with my car. anyone got a clue?
