If the tps was bad you’d get a code. If the second cts is going to an aftermarket gauge, how is the scanner seeing it? Last question, what is the fuel pressure doing when the engine sputters and dies?
Regarding cts I was puzzled why the scanner was picking up a second reading. Made me think if the computer thinks the engine temp is 88f it would not run right. Have no idea why it had a second reading.
I was able to run around and pop hood as it was sputtering, regulator gauge was steady.
I also added a second trunk battery ground to the body, no difference. Hmmm.
