Ok got a 99 tahoe,put a new sending unit in and about 3 weeks later starts running rough check engine light is,read coats check everything in coats running lean random misfire, ok I cange all the things that needed to be changed run Good for a day or two then same thing again, kept not thinking it was the new sending unit never thought about it until I got tired of chasing a ghost, and it was the new sending unit, so I replaced it and then it is running to rich !! Replaced o2 sensors fixed exhaust leaks and now have a hollow sounding knock! Put new cap and roter new plugs and wires and now it won't pull itself??? I give up!
Totally confused!!

Uh….
Wat?
Wat?
That’s good.. I really did lol.
@Obie One, welcome to your first post at the forum.
What freakin' sending unit?
What needed to be changed that you did change? What coat told you that you needed parts?
Your run on of info is impossible to follow or to attempt to help you with.
You have typed out and laid out a shotgun scatter shot of info and problems.
Wild guess, you replaced a coolant temp sensor? Am I close?
