Question about 1999 Pontiac Grand Am GT
I have a 99 pontiac grand am and it has a stutter going up hills and now a real rough idle at red lights what could cause this
It could be any of the following:
time for a complete tune up ( plugs, wires, cap, rotor )
it could be thatyour ignition timing is out
you mayhave a clogged fuel filter
your injectors may be dirty
or you may have a vacuum leak
any of these could be the cause for your problem.

Sounds like a vaccum leak to me. check all your vaccum lines. thats where i would start.
