TPS or Knock Sensor??

kewlcoconut · 09-27-2005, 07:49 AM

My supra has been acting up lately. It is idling pretty weird. If I drive it for about 10 minutes or more and then turn it off, and start it up again about 20-30 mins later, the RPM goes up and down like the car is breathing really heavy. The RPM needle just goes up and down really heavily and the car sounds like it is going to stall. Once in a while it will fluctuate so close to 0 RPM that it will just stall. My engine light is on, and it says my knock sensor and TPS have errors. I took it to my mechanic, and he checked it out, and he said it was the knock sensor. But I want to make sure thats the case.

Any help/suggestions??
