Takes off!!

I have A 98 zx2. Yesterday i was driving down the interstate at 70 mph. I let off the gas and it was almost like the throttle was stuck but it was slightly accelerating. I don't have cruise control. After putting my foot on the brake and pulling up on the e brake it finally stopped. I am pretty good at working on vehicles and the throttle linkage and everything works smoothly. This is very dangerous and I need to get this fixed it could cause an accident. Also the computer does not throw up any codes. HELP!! THANX!!

wel the basics, make sure the cable doesnt stick, make sure the TB is clean and the butterfly has smooth action, also check for air leaks.

My throttle would stick when driving but i could never get it to stick when I was under the hood. I just cleaned it and lubed it and it never did it again

This happened to me once, as well as in another car. Make sure that the bottom part of the accelerator pedal didn't get snagged by the floor mat.
