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.
