Engine problem
2002 Oldsmobile Alero 4 cyl Two Wheel Drive Manual 113000 miles

I had my car towed home because the engine was shuttering. If I tried to drive it would try to stall, if I tried to climb a hill, all power was gone and would stall. We scanned with a universal code reader and the code was 300. Any suggestions? We changed sparkplugs and it looked like 1 and 4 were fouled but still no change

There is a coil that controls the #1 and 4 cylinder. Replace the 1-4 coil and if it still stutters then also replace the ignition module. This will fix your car.
