Thread: Suddenly my engine is running rough

Tweet

My 70 Chevy pickup was running great this morning for about 1/2 hour, than suddenly it the engine began running and idleing real rough. I didnt really die, just rough like its not firing on all cylinders. I checked all the connections from the distributor, they look fine. Any ideas? My gas was running low, so i added some, but the rough ride continued...

Any ideas???

INPUT: is that the first 1/2 hr. on the motor has it got 100,000 miles on it. How old are your wires, plugs, cap, rotor, gas, is it running rich?

The motor was recent redone into a stroker 383. The distributor was replaced along with the wires and cap. I have not tested to see if the plugs are working properly. Some buds of mine think it could be the fuel filter. I am not even sure if i have a fuel filter installed.

Could be you got a bad load of gas,,,,try disconnecting the fuel line from the fuel pump inlet,,and then hookup a line to a jerry can if you suspect bad gasoline,,it'll run nice if it is bad gasoline in the tank,,,it might be an idea to go back to where you got the gas from, and ask if anyone else had problems,,,,,,,,,,,,,,,,sometimes the obvious can drive ya nut's.

I would for surely be looking at my fuel system especialy if you have no filter at all. maybe plugged jetts then. why would'nt you even check to putt a new fuel filter on especially with new motor????

i will check the fuel lines. Do you think some fuel cleaning additive will help...?

however, my suspesion is that a cylinder isnt firing...

if u think a plug isnt fireing find the kulprit
