1997 Chevy pickup running rough

Initial diagnostics showed misfiring. Replaced plugs, wires, rotor, distributor cap and coil. Had to replace injector for cyllinder #8 which fixed the misfiring, but still running really rough. Mechanics are baffled!! Any ideas? It runs roughest between 1500 & 2000 RPMs

1989 Chevy 2500 pickup. Two months ago I was driving and truck just died. After it cooled off it would crank for maybe 5 seconds then would not crank. Replaced plugs, wires, cap, rotor, and coil. Still...


You can have the coil and module tested at most auto parts stores. The module provides the ground signal to the coil. It could also be the pickup coil in the bottom of the distributor.

Ok I have replaced the Distributor, Cap, Rotor, checked all spark plugs and my 93 chevy c1500 is still jumping RPM'S when driving and will shut off! Can someone please help me??/


It could be a fuel problem, the pickup coil in the bottom of the distributor, or the ignition module among other things.
Someone would need to figure out if the ignition system is causing the problem or if one of the injectors is failing.

Dodge stratus misfire, runs rough has random misfires in cylinder 1,3,and 5 and a vacuum leak, I,m not too worried about the leak unless it is related to the misfire


I WOULD REPLACE DISTRIBUTOR CAP AND ROTOR.MARK LOCATION OF ROTOR OR MAKE NOTE SO YOU CAN INSTALL NEW ROTOR IN CORRECT FIRING POSITION. IF THIS CAR HAS A LOT OF MILES I WOULD REPLACE DISTRIBUTOR CAP, ROTOR.SPARK PLUGS AND WIRES.REPLACE IGNITION COIL.CLEAN FUEL INJECTORS, FILL GAS TANK UP TO 3/4 TO FULL TANK OF GAS POUR CAN SEAFOAM IN FUEL TANK IT WILL FLUSH OUT THE FUEL INJECTORS WHILE ENGINE RUNNING OR DRIVING CAR. REPLACE FUEL FILTER. REASON I SAY DO A TUNE UP PROBLEM COULD BE MINOR FIX.COULD NEED TUNE UP.IF TUNE UP DONT HELP THEN YOUR PROBLEM IS DISTRIBUTOR OR THE CAMSHAFT SENSOR INSIDE OF DISTRIBUTOR.THAT WOULD SET OFF CHECK ENGINE LIGHT.BUT I WOULD SAY TUNE UP COULD FIX PROBLEM.

Is this a 5.7? They are notorious for intake manifold gasket leaks. When mine did it, the diagnostics blamed it on an ignition misfire also! Replaced the gaskets and it runs smooth!

#4 cyl misfires/code 304


P-0304 indicates number 4 cylinder misfire. Are you using Toyota parts dept spark plugs? More often than not, non-toyota plugs make the v-6s run poor, right out of the box....
Try this:With the engine running, pull the connector wire off of the #4 injector. Note to see if there is any change with the idle quality. No change? You may have a bad injector.
