Check engine light comes on, rough idle wants to stall, gets a little rough during idle, at 4000 rpm starts to hesitate while driving.
Distributor started having a rattling noise. I replaced the rotor and top, didn't help. Also generated lots of ignition noise in the radio. Local dealer repaired.
the truck wont start until I tap the distributor cap.
truck starts when cold drive it 2 miles and it stalls after a few seconds it will restart
Being from Western New York, My problem was caused by excessive corrosion in and around the distributor packs. This caused short condition which actually blew the fuel pump fuse. This must be a common problem, because it had happened to my previous truck. 1994 Chevy S10, same engine.
I lose and gain power while driver and radio has hissing sounds
engine turns over and sputters but will not start after sitting for a week without starting and warming up ever day. Replaced distributor cap and starts and runs great until it sits.
Ok my problem in slow speed pick up fails if I pressed the gas and go fast stop fail and some times to starting the engine takes time
Had to replace distributor
engine runs rough and has a lose of power.
