I have a 94 buick park avenue ultra and it says premium gas only which I didnt notice until now and I bought it about 2 months ago and have been putting regular in and now its running rough and knocks and shakes pretty good whenever I hit 50mph what would u say the problem is? Do u think the regular gas could have been the problem?
