i have a 1995 chevy suburban, about 2 months ago it started with a problem. when i am going under 20 miles it seems like it wants to turn off when i accelerate. i changed the idle control valve and the egr valve and sensor but it's still the same. what can it be????

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.
