I have a 1996 GMC Sierra 1500, Vortec 4300 engine, 5 spd standard transmission, 202500 km. Sometimes when it is wet and rainy or first thing in the morning until the engine warms up the engine will stutter a bit between 1,000 and 2,000 rpm. I have replaced the plugs and wires last week, and the distributor cap and rotor button were replaced last year (I had them out and they still look like new). It doesent feel like 1 cylinder is missing it feels like the whole engine is. However the engine light never comes on. Im wondering if it is either the coil, the oxygen sensor, or the EGR valve. If you could help me out with this it would be great. Thanks.
have the same problem?
