I have a 95 contour gl 2.0 l zetec. new plugs, wires, coil, iac. And it still chuggs at full thortle and take off. I have had the codes ran but noone can seem to tell me what the porblem is. Take off is fine if I full thortle it but the i have to back off rite away. the codes I don't even have anymore. cell pops on and off runs the best when it is warm. not cold but not normal temp.

Please help....
