hey guys just signed up at 2gnt and searched for similar problems and couldnt find one

While drivin, usually highway the car seems to studder? Usually it starts happening in 3rd gear around 5000-5500 rpms under heavy acceleration but has happened in other gears.. only happens for a few seconds and goes away once i upshift into next gear. It does not happen all the time and when it does happen i notice the rpms raise to 6 1/2k drop to 5k and back and forth really quick

any ideas? the only things i have on my car are 4-1 header, catback and intake its a 95 gs

I'd look into some new spark plugs and plug wires. Autozone carries the Bosch direct replacement wires with lifetime warranty and they're all you'll need for a long time.

thanks ill check that out

No problem. $40 should be all it costs. Bonus is that, should the symptoms come back two years from now, you can just take the plug wires back to Autozone for a free replacement. :thumbsup
