My car started surging today when I am in drive at speeds between 50 and 60-65, once over that or under acceleration, the car does not do it. The surging is very light and goes away with even light throttle, I replaced the TPS just a few months ago.

Doesn't really sound like it in your case but my surging was caused by a faulty MAF sensor.

Sorry everyone, been really busy. Had the car scanned and came up with 4 trouble codes, 2 for the EGR, 1 for misfire and 1 stored for converter slip. The reading for the EGR was 7% at key on, so the egr was totally trashed, replaced that today, and doing my plugs and wires tomorrow. 1 plug wire was burned or arcing, and one or more plugs may have fouled from the egr. Good news is NO KR!!!!!

could my spark plugs be part of my surging with no CEL on..? my throttle body plate doesnt click when i let the lever go...the plate closes but the lever kinda bounces back...i dont want to waste money and change my TCC solenoid when it could be somthing i could tackle...but every time i throttle up to 30-35 mph the car jumps to the 1500 rpm range...could it be MAF without CEL..? it stops this one i release the gas pedal or tap the brake while still throttling...please help
