Clogged injectors can give you hesitation and sputter and spit run a few bottles of seafoam and Lucas burn hot over a month or two or marvel mystery oil I prefer marvel it seems to work on everything then change your fuel filter
First do a power balance test. See if your running on all four cylinders. Them compression and leakdown test. Then start trouble shooting injectors spark plugs etc. start with the easy stuff work your way up
Well its stupid cuz now that I want to be driving it everywhere to burn all that seafoam through it I have a wicked loud vibrating sound comng from my left front wheel. Only happens for 20 seconds tops but its quite annoying and I dont wanna drive on it alot until I know what THAT is... jeez! One thing after another!!!!
Jack it up check the front end maybe . loose caliper bad wheel bearing give it a inspection lucky front end parts aren't to expensive
