Larry -

If they fit the distributor cap well, bring 'em...... I put on a set of cheap AutoZone wires that don't fit the cap very well.

Today, the engine ran better than ever...... cruising effortlessly at 3500 rpms (85mp) and pulling grades at 85-90 mph without ever going into boost..... even dusted off a 210HP 3.7L new Dodge Nitro..... was that guy ever surprised when he tried to show me his <img src="/forums/images/graemlins/butwiggle.gif" alt="" />. <img src="/forums/images/graemlins/lol.gif" alt="" />

But, just as I almost completed the 225 mile trip and turned off on the ramp, I poked it hard and the surging came back. Leaving work, I restarted without using MegaTune and it ran fine again.

I find it interesting that every time the problem arises, I am near the end of a trip with a nearly empty tank - so, thinking I might have gotten some bad fuel, I went to another station today that I used about a month ago for 10 or so gallons in hopes of eliminating a cheaper and seemingly riskier Conoco station I have been using. As I was filling up, I noticed the small sticker below the grade selection buttons that stated..... "Contains Up To 10% Ethanol"....... hmmmmmmm.... I didn't see it before (after dark), but I nearly missed it today in broad daylight, so I assume it was there all along.

Cleaning Tanks
If another type of fuel was stored in the tank that will be used for the E85, it must be cleaned because storing gasoline underground causes some particulates to settle out and form a sludge. Introducing alcohol into these tanks will place this sludge into suspension and will lead to serious problems with vehicle driveability. There are several methods for cleaning sludge from the bottom of a tank. Each method must be completed by a certified and bonded company familiar with cleaning petroleum storage tanks.

The Side-Effects of Ethanol

The first problems encountered with transitioning to E10 is the loosening of sludge from the fuel tanks. Ethanol is a very effective solvent and it will attack varnish, gum, and resins: the sludge that can build up in fuel tanks. Once cleaned off the fuel tank walls this build up leads to poor performance and frequently clogged fuel filters and injectors. The enzymes in Star Tron« will safely break down and disperse this sludge. After a filter change or two the fuel tanks will be clean and boaters can move on the next, more serious, ethanol related issue...

Maybe? Time to clean the tank and change the filter again I guess. <img src="/forums/images/graemlins/confused.gif" alt="" />
