Shuddering from 1200-2200 RPMS...help plz
 

Hey guys, I own a 95' GS and im lookin to learn some more stuff about it in hopes to be able to do all of the work on it myself.

Now my major problem that i just cant figure out is this shuddering during accelertion. It happens between 1200 and 2200 RPMS and causes my whole car to shudder, for lack of a better word. Once i get above 2500 it's clean again with no hesitation. This has only gotten worse over the last 2 weeks...meaning that it happens almost eveytime i enter that specific RPM range. I'm wondering if it has something to do withmy coils, or something as simple a spark plugs. Any help for anyone out there would be great...thanks.

Spark plugs or spark plug wires

Sounds like its misfiring.
When was the last time the plugs/wires were changed?
Also, check the PCV and EGR valves, and the carbon build up in your throttle body.

good ole classic NGKs

Another thing to check is your TPS. Do you have a Haynes/Chiltons manual? They have a TPS check in there. It just sounds odd that you bog out at those RPMs and not all over the place.

I dunno... I could go either way... but if it were an ignition problem wouldnt it go throughout the whole powerband? Not just certain engine speeds?
