Error codes cylinders 4, 5 and 6 misfires. Replaced sparkplugs ignition coils and fuel injectors. Error codes disappeared and car ran perfect. 30 minutes later ssne cylinder misfires pop up. However, thing is when I clear codes with diagnostic tool, car runs smooth and perfect. Yet 30 minutes later check engine light comes back on and car misfires. Believe problem is with actual ECM instead of actual cylinder misfires. What could be causing this?

Compression is good. All sparkplugs ignition coils and fuel injectors are new.

That's been a while. I honestly couldn't give you an exact number. But all were over 100 PSI. Very little differentials.

I would retest and get the exact numbers. It makes a difference. You should have 140-160 pounds. If you do not, that could be the issue.

Will do. Thank you. So you don't think it could be an ECM problem?
