Have a 93 Chevy Silverado that has a problem with hesitating when accelerating. At steady 1000 rpm it also seems to be hunting.
It started when completing a cam change: Replaced cam and left off the negative battery connection to the engine (intake manifold). Cranked engine - no start. Found that wire was not hooked up so fixed that. Checked distributor cap - carbon connector in top burned out. Replaced that, replaced module in the distributor and replaced the engine coolant sensor.
Anyone have any experience with this? ECM need to be replaced? Have OBD 1 running data reader but not real experienced at this.
