2000 gmc jimmy 4.3 6s..
So I have a 2000 GMC jimmy and I have this
problem that when in driving and I go pass 50mph
it just shuts off and battery light turns on...but I just
got a battery like a week ago...I've changed the
spark plugs and the spark plug wires...I've changed
the gas pump and gas filter...I've changed all the
o2 sensors and mass air flow sensor...I dont know
what to do anymore...I really like my car it's just
always something new to fix...can someone
have you looked at the motor mounts? and the tranny mounts too, one could place a floorjack and woodblock to see how well they are holding, have had it so the ignition shorts out on acct of these, have had it so the accelerator pedal went to full like on my 59 pontiac~
sound like solid ground to the chassis needs a tend to~
No I haven't checked motor mounts...you think that would cause a problem?
