My SHO is s-s-s-STUTTERING!

[GM Reszel]

Hello everyone thank you for this forum! I have a 93 SHO. As I'm driving, whether I'm accelerating or decelerating as I get near about 2k rpm the car jumps and stutters in power, sometime rather violently. The engine light comes on every so often but never in correspondance with the stutter problem. The problem doesn't always happen in this area of the power band but does happen quite frequently. I have just recently replaced fuel filter, plugs, wires; I almost always run premium.

Any expertise would be most appreciated, email me or call,
Best regards,

Did you try cleaning the MAF sensor? TRy running with the MAF disconnected and see if it's any better or worse.

Make sure that you dont have any vacuum leak in the canister behind the intake manifold. A little hose coming from it to the manifold was making my car stutter pretty bad in the past.
