im have trouble with my 94 z28, everything seemed fine until earlier today, now when i drive it and the rpms are below 2000 it feels like the car wants to die on me, it just dont have anything in it but then it pops back up and revs up again. it feels like something is clog or something. Any help would be appricitaed thanks

 

Wow sounds like the same thing my 94 Trans am was doing. Till I recently pulled the intake found metal in my oil, and am now doing a rebuild. I don't think the two are related, but I'd like to know how you fix it. Cause thats gonna be one more thing to add to the list...

But of course my car was making a valvetrain noise like a loose rocker arm.

 

new symptoms, its now when i start it up struggles to start then once it does idels around 600 and feel likes it just cant do any thing.

 

Is your ses light on? Does it feel like a misfire or just like it just doesnt have the power?
