1996 GMC Safari SLE 4.3L Surge, Misfire, MIL Lamp on
Posted to GM Driveability on 5/8/2003 5 Replies

One of the guys changed an engine in this van, not sure how many KM on it, since the swap it idles great, if you raise the rpm up to 1500 or so for 30 seconds or so then let it go back to idle, the engine will miss quite bad for a minute then return to idleing...
