truck starts and runs but when taking off and trying to give it more gas to go faster the truck acts like it is running out of fuel but has fuel. runs and then stalls but does not quit. thought I had water in the gas but put in a bottle of "HEET", still does the same, runs and then feels like it is chained to a tree, but like I said it never dies.
Engine hesitates during acceleration, feels like a electrical miss. Once up to speed seems to settle down. Have replaced all ignition components and various sensors to include ignition switch. Still acting up. Never thought distributer would go bad. Hate to spend another 100.00 hoping it will work but running out of options.
Changed cap, roter, distributer, and all plugs and wires still acting up starts when cold and dies shortly after getting to temp
Starts without any issue but when accelerating the engine seems to be muffled and will only give full power to accelerator when I reach speeds of 50 MPH.
rough acceleration,occassioonal backfiring, occassional stalling,poor gas mileage.
had problems with rough running engine and would stall while idling at stoplights. while driving still ran rough but only wanted to stall when my foot was off the accelerator, slowing down or idling. had to replace distributer assembly. check engine light came on multiple times during this issue.
engine started running rough on freeway wasnt overheating at all. but the engine cut out and wouldnt start back up at all
The truck starts up just fine but sometimes when I accelerate it acts as if it doesn't or can't accelerate very fast. It takes a little bit of time before it will accelerate. Typically it has issues around 50-60mph
Idles fine and starts fine. Just slowly started bogging during acceleration last week. Replaced cap,rotor,plugs,wires,coil last month,fuel filter today. With this high miles, original motor and distrubutor hmmm could be the distributor? ? Today bogging will not stop. Fastest I got on freeway was 50mph.
it starts with throttle floored and runs rough the eng com was replaced and now it wont start at all
hesatation at 40-50mph-changed lots of parts-had timing checked and reset about 30 miles and back to same story. i bought a 10mm distributor wrench,reset timing sliped 35 miles.i will pull distributor and check gear,some were bad,not hardened.will end with changing it out.hope for the best.
It appears shaft lift in distributor is destroying cap and rotors. Replaced distributor unit twice now. Body is plastic.
It began about 4 months ago. I could feel an odd vibration in the gas pedal that accompanied a rather odd vibration/buzzing noise when accelerating. Truck started running really rough and chugging pretty bad when leaving a stop light, but would idol and cruise at highway speeds fine. Finally died on the road last week so I took it in.

The distributor shaft sprocket was worn down so bad that it had finally lost contact with the cam-shaft and stopped turning the distributor rotor. Cost $340 with labor and parts.

If you feel a odd vibration and hear a funny noise from the area of the gas pedal, check and see if your distributor is the issue.
I go up a little hill or have a head wind my truck would slow way down causing me to have to down shift. Still don't know what the problem is.
