By "was" you mean that you're giving up and swapping the motor? Seems like you were almost there, the "runs good when cold but bad when warm" is a pretty big clue. Open loop versus closed loop maybe. Seems like your problems are changing though, which makes finding a solution difficult. Why would changing spark plugs make it run better when cold? Unless it ran better when cold before and you just left that part out in the first post. Clear descriptions of what's happening are really important. All we have are the words you right.

Spending extra money because of people on the internet makes no sense. Actually, doing anything because of people on the internet makes no sense. Getting angry because of people on the internet, for example.

Good luck. You need to get some sleep.

 

Cats bad? Cleaned and/or replaced iac? Throttle body cleaned? Maf sensor clean? Fuel pump strong? Running rich? Running lean? Have a obd II scanner to get real time fuel trims? O2 sensors working properly? All electrical wires in good condition? You sure all your new parts are working properly... new parts can be DOA... there's a million things to test...and/or replace since you like throwing money at the problem... come back with a better attitude and people like Jbrew can do wonders helping you diagnose your problems. Otherwise we won't miss ya when you're gone.

You're the one that dumped a ton of money on a problem before asking for help, so you're annoyed you still have a problem (sucks and most of us have been there) now everyone is trying to help but you never report back so if you're too busy to post than you're too busy to be helped.

Imma go enjoy the rest of this snow day with my husky since I'm not too busy today

 

I'm ase certified and went thru the motions... I posted here in case someone knew of something not regularly found to cause these issues I'm having .. But obviously no one does...thanks again for everyone that tried to help and **** y'all that just wanna talk ****..
