been doing a little more digging. the very small line seems to be an electric line. it goes to a connector at the rear of the engine. there was so much dirt and gunk etc down in the valley i couldn't tell what it was.
also been driving the truck a lot and experimenting.
when i am going 60 mph and go to wot it goes up to 3500 rpom and just stays there. if i let up enough for it to shift it begins to accelerate on up to 85 with no problem and goes into lockup (converter ) when i ease up on throttle more. all seems normal unless i put it on the floor in high gear, it accelerates at wot from a stop good ,
it has a new aftermarket tpos on it and same as the old one. pulled a small trailer this morning and no change .
it will go fater than 85mph, i just stopped at that speed. it was still accelerating and with the trailer on it.
cleaned mass air flow sensor , new fulke filters, plugs aren't that old, new tps, new intake, new coils, and no check engine light,
could it be a bad new tps??
any help appreciated.
