I have imagined a sort of hestitation of sorts when driving around. Today I noticed something new, and I was hoping you could help me diagnose it. When I hit the gas pretty hard, the car sort of rumbles like it's trying to do something and doesn't, and then all of a sudden the car picks up and I'm thrown to the back of my seat. I was thinking fuel related? I have a 94, with 208000 miles, CAI, and Magnaflow cat back. I think the last time I changed the fuel filter was 2 summers ago. My opti was replaced in September too. I hope I get some feedback! Thanks!

You should change the fuel filter at least once a year.Try some injecter cleaner too.I use Valvoline syntec with great results.When did you last change plugs and wires?

 

Yeah, I've run that fuel treatment Valvoline stuff through once in a while. The last time was probably a month ago. I also had the plugs and wires changed last month. I also just put in the LT4KM. If you need any more information, I'd be happy to tell!

 

See what the fuel filter does for you.Ever use Seafoam?With that many miles you might want to try it.
