Hello Scotty, great site and videos. Anyway I have a 2001 Acura tl. It is hesitating when driving. I changed the sparkplugs, tried mystery oil, and additives, use premium gas only, but it is still happening. Seems worse at around 50mph and really wants to stall out when just started and put into gear. Also seems worse when slower acceleration and not so much when you punch it. Is it possible that its the fuel filter or electrical? I have limited experience with mechanical issues and would really appreciate it if you could give me some advice on how and what to test for next. Thanks. You da man!
