It would only do it when it was missing. Replaced spark plugs. Old ones were fine but OEM. Upgraded to new ones. If it was valve train would of shown on plugs. Noticed my 6th cylinders boot was torn. Buying new wires. Will see if that was the problem. Also going to clean fuel system with techron

So did some more tests today. Fuel pressure is totally good. Maf sensor is working properly. Almost sounds like the car is missing. Shakes more at an idle and still making popping noise from intake here or there, strange cause sometimes the car runs fine for a little while. I have koeo codes, 326,332,335,536,558. Then koer codes, 116,136,326,538. Please someone help me!!!!!!
