Thanks for the info. Going to grab both sensors and a rebuild kit for the throttle body. I'll do the repairs one at a time so I know what fixes it, and I'll keep you guys updated. Thanks again for the helpI got it. You can unplug the temp "sensor" and see what happens and you can pull the IAC valve and check the pintle and clean and use carb clean when you do. The port where the pintle moves is also known for carbon build up and can be cleaned.
You have a coolant temp sensor for the fuel injection system. Acts like a choke. You have a coolant temp sender that feeds info to gauge. The sensor will be right at the thermostat housing. The chugging feeling is a classic sign of a fuel delivery problem and even though you have a new fuel pump and filter, there still may be fuel delivery system components causing problems.
