hey guys...today while i was trying to diagnose my problem i noticed it has a rough idle and a miss thru all rpms. when the miss occurs it sucks paper thru the exhaust i checked timing. tps and idle adjustment. all my vaccuums are right. does this mean my valves are burnt or to tight. my motor is under warranty whats the best way to see if my valve's are burnt. im gonna rip her open right now to see if there to tight other wise i guess i gotta do a compression test correct. are there any other things to look for. the motor only has 15,000 miles on it its reman recon motor thats still under warranty! any help will be greatly appreciated
