So I have the SUV listed above with the EFI throttle body. When it is cold it runs great. As soon as the temperature comes up, a whole slew of problems happen. From a complete stop, if you mash on it, it will fall on its face spit sputter and shut off. I did some digging, and my own self diagnosing, (unplugging sensors) I got to the coolant temperature sensor, unplugged it, ran great when warm, terrible when cold. Plug it back in, it does the opposite, so I put a new sensor on it, still didn’t fix the problem. No other sensors fixed the problem, so I pulled the wiring harness, and went through it. Every wire, every connector, found an alarming amount of shorts, and bare wires, fixed properly, (soldering and heat shrinking) reinstalled, still horrible problem. Am I missing something?
