Hi,
I have a 2000, 2WD, 4.3 Chevy Blazer with 95k on it that idles ok and can be driven in reverse ok, but stutters and stalls when in drive. Spark plugs, Crank sensor, PCV have been changed. Fuel pump is ok as well as IAC. Transmission fluid checked and visual of vacuum lines appear ok. ?

Hello, it ended up by being the crankshaft position sensor connector. Changed the connector and the sensor again and all is well. Thanks. :)

Any codes? Could be a trans problem. Check the wiring harness for rub-through where it crosses from the engine to the PCM near the battery. The hose clamp on the heater hose can rub into the harness and cause all sorts of trouble.
