10$ item- big help!
10$ item- big help! I've experienced a problem with my car hunting for the idle.. then idling down slowly.. and it has driven me crazy with datalogging with SCT and a Snap-On tool. Idle air control? Throttle body screw? Vacuum Leak? Goofy tune?
Then-
I had to replace the grommet for the filler tube, so while I had the tank down, decided to replace a $10 dollar item:
It had some rust and even with the right fuel line release plastic tool it took some work.. it even had a bit of a kink- nothing much.
Filled the car back up- same 93 Octane stuff- and whoaaaaa!!!!!!
IDLE is now almost rock steady, despite the cam(s) and othe mods!
I nailed it in 1st gear and it fried the Kumho's to a crisp!!!!!!
I guess the moral of the story is.. change you fuel filters every so often!

Oh yeah...I always tell anyone that's just bought a higher mileage used car or even someone that has neglected their car that they bought new to change that fuel filter along with the plugs and wires etc...it's potentially the cheapest/easiest yet most overlooked item to swap (on most cars) that can also solve a series of ailments in one's vehicle. 
Also a good point.

The filters are usually a paper material and not impacted by ethanol. What you need to watch is the particulates in the gasoline.
