So i've been pulling the code P0300 for like a week now and my 1996 Deville just doesn't want to cruise down the road at a normal rpm... i have to hammer on the gas to get down the road without the car running all jerky... it really feals like i have a fouled out a spark plug or maybe a bad injector or something... some one help... please...

Have you had the fuel rail recall done recently?
