My k6 has been having issues sense i bought it. It has 15k miles so not too high and was straight piped when purchased. I put a pipe on it, new airfilter and plugs because it just wasnt running correctly, also valves were checked all was well but im still having a rough idle. What should i check next? coils? fuel filter?

Dealer mode allows you to adjust the TPS. Its free and easy to try. start there.
The TPS adjustment procedure is on 4-20 of the service manual. Be sure that you loosen the TPS mounting screw and not the nearby and easier to reach STPS screw. The tach tends to read high so adjusting the idle to 1200 RPM is better.
Page 10-8 of the service manual says:
It sounds like you've already done the first item and I'd expect new plugs to be properly gapped. Have you checked the compression? A fuel filter problem would normally show up as bogging under high load and RPM, instead of at idle.
A straight pipe suggests an irresponsible previous owner, which makes me worry about the condition of the engine.

thank you, im going to try the paper clip method tomorrow morning.
Honestly, im not overly mechanically educated however i can do basic things. I pray that its nothing internal but will it throw a code if it is a bad valve seal, bad camshaft, or anything related in that area? Coils are going to get replaced next i have a compression tester i will run tomorrow. I just got my clearances checked everything was fine new plugs and a new cct. Ill run some sea foam because the gas has been sitting for over the winter with stabil in it however it wouldnt hurt.

There's nothing sensing compression, so you wouldn't get a code for a bad valve seal. If the cam position sensor (CMPS)) was not working correctly you'd get a code.
