Question type: Maintenance & Repair

1996 Buick Century very rough cold start idle. I have to pump the gas to keep it
from stalling; and the car automatically revs to keep the engine from stalling.
"Check engine" light stays on .  I've replaced the oxygen sensor and a leaky
hose to the air filter, which has helped some.  I've considered a tune up; but
could a bad fuel filter be the main problem?

I had the same problem with my 97 Buick LeSabre and I had to get the fuel pump changed

the ignition control module for both the 3.1l and 3.4l are identical in appearance and all wires and plugs fit. So now my 3.1 is running on a 3.4l ignition module. Is this O.K.?
