I am not a real mechanical wizard and have no real automotive tools, just my ohmmeter from radio shack.
Anyhow, my van - suddenly one fine fall day - would not run without 'feathering' the gas pedal. I replaced the fuel filter ('bout 45k miles) and it ran fine - for about two weeks.
The old filter didn't seem to be clogged up, but perhaps slightly more restriction than the new one.
It will start and I can drive it if I keep the rpm's up with the gas pedal...hate to do that...
Anything of a basic nature I could check before taking it to the dealer? The only thing I can think of to do is replace/recheck the fuel filter again - which might indicate trash in the tank. Odd that the problem would correct after I replaced the filter the first time...
I would think that the filter would affect how it runs and not the idle...
Air filter is clean and that ain't the problem.....john
