99 Jimmy engine question
My Jimmy is acting up again... I can
drive it for a while and it's all good
then all of a sudden, if I yet to slow
down, the rpms go up and the engine
revs, truck tries to accelerate .
Breaking is a challenge. Finally the
rpms go down and the moment I let
off the break, the rpms jump back up
like I'm trying to race. It seems to
stick at like between 10- 30 mph. I'm
worried about it. Idk if it's a throttle
position sensor or my transmission
or accelerate cable hanging up. .
Confusing. Also my engine light is on
but I think it is because of my o2
sensor needing replaced.
