RUNS ROUGH - INTERMITANT

Chevrolet Cavalier

1998 cavalier-2.2 standard-218k kilometers.
have new plus, new plug wires. Code reads muliple
random cylinder misfires. Will be running good then suddenly starts missing and sometimes you have to keep it reved up to keep it running. Also noticed it does not start as well as it did. I suspect map sensor?
Code was showing up before changing wires and plugs. Coil packs or injectors have not been changed, I did check injectors for leaks, couldn't see any.

Did the code show up before of after the plugs and wires?

Have any of your coil packs or injectors been changed recently?

Sorry, that was a stupid question on my part.

I would suggest having your injectors checked again. It may be they aren't atomizing the fuel properly once the engine has warmed.

It finally registered a code. Egr was acting up. Cleaned carbon out working good now. Thanx everyone for your help.
