I have a 75 dodge D100 with a 318, and it recently
started having problems when idling. It doesn't
want to idle on a cold start I have to feather the
throttle to keep it running. And when I'm driving
and let off the throttle to slow down it pops and
backfires out of the exhaust. Usually it will idle
normal once it s warmed up but if I let it sit and idle
for a minute or two then the engine will die but it
will always start back up with no issues. Any help
The popping maybe a timing issue so check the ignition timing. The idle issue may be the choke out of adjustment. How long since you tuned the truck up?
I did plugs, wires, distributor, ballast resister and ignition module about 6 months ago
I would check the timing, maybe it has slipped. Look for vacuum leaks and exhaust leaks.
Thanks for the advice
