So I'm having misfiring at 3000rpm and above. Before it would do it idle and below 6000rpm, now after a while of normal operation it would do it above 3000rpm.
I changed all plugs and coil packs with brand new. Ohm them and they are within specs. Tested fuel injector and they work, dont know if its clogged. I tested fuel pump pressure and it's 40psi. It ran fine when i added fuel injector cleaner so maybe fuel injector problems?
