You have 2 options you can, A. throw parts at the car (not the smartest way to repair a vehicle) or B. you can run some simple diagnostic tests. I'd start with reading the codes that are stored in the ECU, if any.

I would run a compression test also. Makes sure the engine is fully warmed up, pull the 15A EFI fuse while conducting the test and hold the throttle wide open during cranking.

I did a diagnostic check on the car and it told me the TPS was messed up. I check it and it wasnt working right. I took it of and went to the parts store and the replacement that the computer says isnt the right one. I have a M125 /89452-28030 /198500-0300 TPS. Can anyone give me a cross reference to a Denso so I can get my car back on the road. Thanks

OOpps I tought yours was a Turbo.

How do you know its bad??? Its probably not calibrated correctly.

I put a new one on and the car still runs bad but the computer keeps saying the TPS is still bad I dont know really what to do and my friend says its a head gasket but I dont think thats it but he is a master toyota tech. but he hasn't listened to it in person. I think im going to take the spark plugs out and see if there fouled. I have allready pressure tested the coolant system to see if im losing coolant to the piston, or oil and im not. so i think im going to take it to the shop to put it on the diagnosic machine. The test I ran was though the check engine light. (dont know how effective that is)

Listen

Did you calibrate your TPS sensor????? The TPS is not just something that you just screw back thorttle body.
