Sorry for the late reply.
Have you checked the throttle position sensor? To check, you could use a digital multimeter on the signal wire for the tps. Turn key just till the dash lites come on, you don't have to start it. Then work the throttle by hand while you watch the voltage reading. The reading should move up/down smoothly, if not, sounds like the tps.
