1987 GMC Sierra R1500 4.3L, stalls and shakes and HELP.
My truck will die in the morning whether outside
temp is cold or hot. Recently started occurring. I've
replaced distributor, TPS, adjusted my idle because
it was too low, my fuel pump works fine. New
alternator and battery. I believe I have a small oil
leak, truck is also mildly rich smelling and has
always been a tad rough-running but it just started
dying around a week ago. Thought it was a coolant
issue but we tried 50/50 and just water and no
change. I really need help as this is not my truck
and I have to keep it running for someone... But i
need to know what to fix. I'm a learning mechanic
so please word things on a beginner level. I
appreciate any help in advance.
