My 95 firebird formula has had a weird stumble issue between 1200-1800 rpms around 48mph. below 48mph it drives fine at or above that speed if i press on the accelerator rpm dont budge but i hear the engine speed up until about 50% throttle then it will jump to about 2k rpm and drive fine.....if i let off the gas while its doing this the car will stumble and jerk a little. now after i got my ALDL cable in the mail i hooked up my laptop with the 94-95 scan program and only DTC it pulled was code 32-EGR failure. would this egr failure cause my symptoms or should i look else where? after i get my issue fixed i plan on installing headers so i will probably end up deleting the egr anyways so i would hate to replace it just to chase this problem.
