95 Blazer 4.3 Hesitation

[luiscruz15]

Hello everyone. I have read a ton of threads about my issue but I have not seen a solution to the problem. Here it is. Its a 95 blazer 4 dr. 4.3 (w) auto. 200,000 plus miles. The truck turns on fine but it hesitates between 1500rpm and 2500rpm. If I flored the gas petal the problem goes away, but if I go on normal cruising it will give me problems. When I accelerate slow It hesitates around 1500 thru 2500 rpm. If I hit the gas it goes away. I have check and replace the following parts but the problems is still there. Fuel pump and filter, ecm, distributor and module, cap and rotor, plugs and wires, ait sensor, coolant temp sensor, removed and cleaned the intake plennum and egr valve, tps sensor, cleaned injector assembly. Ran out of ideas. Please help!!!! Thanks

is your distribtor phased correctly

the rotor you removed is the burn markon the tip on one end or the other

when you flour it vacum signal will cause the ignition timing to retard ( if memory is correct )

when that happens the rotor is in better phase with plug wire post

i had a small miss at idle and cruise

turned distributor and the truck runs good no miss, good throttle response, fun to drive

PETE

BUT i am not sure if 4.3 has a distribtor
