the tps is a kiefco or however you say it, the throttlebody looks stock, i believe it was custom done, i'll try the tapping and twisting on the tps and get back to you guys, thanks again!

i tapped and twisted the tps, it stuttered, then resumed idling a little lower, tapped the gas then the idle went back up to 12-1300rpm and stayed there. i have no idea what or where the idle control motor is, more info please

As said before, check your throttle body, I found a leak in mine by seeing meth fly out around the gasket (2 piece). lol..And check everything on your iac..cracked hose ,bad seal etc

ISC motor is that thing between the intake manifold and firewall with hose and wires going to it.

The IAC is an expensive part, if memory serves though (feel free to chime in here more experienced people) there is a way to clean it with standard carb/tb cleaner once it's off the car.

i have phenolic spacers on both the throttlebody an intake manifold. i dont know if the spacers are gaskets or if there are gaskets under the spacers. two more codes popped up yesterday! p1128 and p1586, this is getting really frustrating but im not giving up. im going to check the sensors and hoses that you said to check in your last post along with the throttlebody.

You have a vacuum leak somewhere. The P1128 code is for long-term fuel trims lean. You're getting unmetered air into the engine. First, junk the spacers. They're not worth having and tend to leak. Then make sure the IAC motor is working. Your problem in NOT the throttle position sensor.

^ this.



I would recommend pulling the spacers. they should have had gaskets on either side of the spacer. Make sure you replace the spacer with a gasket when you remove it
