surging
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.

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

Re: surging
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!!!!!

Re: surging
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
