Hey guys, new 94 9C1 with a 4.3... runs great 90% of the time, every now and then though (doesn't seem to follow a pattern) when coming to a stop, the engine with stumble a bit until I come to a full stop, then after a moment the computer smooths out the idle... in other instances, though more rare, and usually right after the previous problem, it will stumble slightly off-idle while accelerating, but smooths out just fine after it hits 2nd gear usually. Any idea?
BTW, I bought a code tester to see if it was throwing codes, but the tester says "1991-1995 GM Cars" and then says "1995-1996 Caprice 4.3 or 1994-1996 Caprice 5.7" ... it doesn't list 1994 4.3, is there something different about these engines? I plugged it in and the Check Engine Light just flashed constantly, no real pattern.

Check the injectors, fuel filter. Sounds like a fuel delivery problem.
Could be ignition, though if it smooths out in second probibly not.
I know it isn't cheap, but some tune up place should be able to plug in and tell you excatly what's wrong.
Something in the back of my mind is saying timming.
I hope "The Voices", don't start again.:crazyeyes
