'99 gmc suburban dies when backing up
My man's 99 suburban has been stuttering when
driving. The rpm gets really low when in idle. When
he backs up it dies. We replaced the rotor cap last
time this was happening and it did the trick for a bj
out 2 months. Then it started acting up again and
back firing just a bit. He replaced the sparks and
cables, and he recently change the throttle gasket
and cleaned the throttle which did the trick for
about a day and it started dying when he backed
up. If I could get a reply that would be great.
Not too sure on SLE or SLT, I will get that info if
needed.
