99 Caravan hesitating on freeway
In the past two weeks my Caravan has been having hesitation (ever so slight but it is there), especially on the freeway. it feels like its a problem from the fuel line. It has 117,000 miles. Could it just be the higher ethanol they are putting in the gasoline now, or would there likely be a more serious problem in the fuel line, and how could I tell?

Thanks, cl8

Re: 99 Caravan hesitating on freeway
if it has not been tuned up yet it is over due. I would start by changing spark plugs, wires, fuel filter, and air filter.

Re: 99 Caravan hesitating on freeway
I can't say I remember the last time I had spark plugs or the fuel filter changed, But in march when I had the oil changed I asked my mechanic to inspect my vehicle because I was going on a 300 mile trip, one way, is that something he could have missed?

How often should those be replaced?

thanks, cl8

Re: 99 Caravan hesitating on freeway
I'm pretty sure I had a 90k tune up but that was quite a while ago.
I just dont want my mechanic to say I need more done than necessary

Yes my neighbor, who helped me with my air filter said he saw evidence of a bad valve.
What I did this year and last year was buy Chevron gas treatment and put that in my tank. It seems to have helped.
I figured it might just be the change in the formula for gasoline in the spring thats hard on my engine.
