for some reason regardless of what gear i'm in when im between 3000 and 3500 rpms my engine feels like it's misfiring, jerking or something, but no check engine light. plus, only happens when engine's hot. Whats the deal?

 

Bump for an answer.

 

Is it stock?

 

humm what mods have you done to your car? i have that same issue with my dc2 on occasions with usual mods I/H/E.

the engine is probably pinging...it might just need a proper tune if you haven't already done so.
