Car Won't Stay Running !!!
I've just finished putting on LT headers, ORY, Cutout, and a new opti with new wires. I crank it over and it runs fine until it heats up and then the car sounds like it's missing / hesitating and chugs a little right before it shuts off. When I try to start it again it runs for a few seconds and then shuts off. Only way to get it running is by pressing the gas while turning the key. But that only last a few minutes until it chugs/ hesitates and shuts off again. Only way it won't shut off is if i key my foot on the gas. I've replaced the TPS, ICM, and COIL. I've also taken apart and cleaned the IAC. There are also no codes. Anyone have any idea what it could be? Any help would be great!
Thanks

It happened to me years ago as well. That is the sensor that communicates with the PCM. The one on the head is just for the gauge in the dash.

it the coolant temp sensor, mine did the same thing. Unplug it and start it and it will probably be fine. If it is the sensor make sure the car has cooled off for awhile because water will come out and it will be HOT. Also you might want to jack up the back of the car so the water doesn't soak the opti.

Re: Car Won't Stay Running !!!
I'm assuming it ran fine BEFORE you installed the headers, and started to run rough AFTER you installed the headers. Since it starts fine cold, and then won't run when it warms up and goes into closed loop, there's a good chance its a problem with the O2 sensors, or the wiring harness.

I unhooked the o2 sensors and it didn't fix the problem
UPDATE:
Now the car wont even start without my foot pressing the gas down. As soon I let my foot of it dies. Also this happens in closed and open loop. Could I have messed up installing the water pump? It almost seems like something is dragging and cutting off the engine. Any idea?
