Search Auto Parts Search Engine surging Sign up here!   Email This Post Auto Repair Home>> Automotive Repair>> Engine Troubleshooting dbanks12 User Apr 3, 2010, 11:24 AM Post #1 of 3 (1535 views) Engine surging Sign In I have a 94 GMC truck, 5.7 litre with TBI throttle body. I replaced the fuel pump about two months ago along with a few sensors, oxygen, AIC control valve,map sensor. Plugs, Rotor & cap. Just recently it started surging when I am at cruising speed and when under load if you let off the gas it seems to not idle down smoothly. Only seems to surge from about 30 kmh to around 70 kmh when holding it steady at one speed. Could it be the regulator that is going, lots of power, idles smoothly in park and good at highway speeds. This one is dumb founding me, any help would be appreciated.. re-tired Veteran / Moderator Apr 3, 2010, 11:41 AM Post #2 of 3 (1533 views) Re: Engine surging Sign In Try a short drive with EGR valve disconnected.
