    TPS controls the ICV so if your getting an irratic idle 1500 and up I would say its bad. There is a way to test it if you do a search. If you perform a "stomp test" and get no resluts it would mean its not working as well.

                My car cuts out when it starts to warm up and it loses throttle. And I turn it off and then like 5 min later it'll do it again.

                    Open up the connector under the intake manifold, the big black round one with 7 pins in it. If they are dirty or corroded your brain will think your coolant is cooler than it really is.

                      Replaced the o2 and coolant sensor. And it'll be to cleveland tn.

                        You test the TPS by checking for continuity between one of the outer and the center contacts.

                        One should have continuity at idle and the other at WOT.

                              Its the connector for the injecters. It connects right by the coolant hoses under the intake manifold should be on that metal piece bolted to it.
