Hi,

I have a 1998 Eagle Talon TSI AWD. Recently noticed
hesitating/pulling at all speeds. Put in some dry gas (I live in cold
NH), and injector cleaner. I changed my plugs and will soon change the
wires when they come in. On a side-note, of the many OBDII codes that
came up including fuel trim bank 1, evap. emissions, there was a
cylinder 1 misfire. I noticed that the boot on the cylinder had a
white hole where I guess it was arcing. I am hoping that changing the
plug wires will solve my problems. Right now, it is only hesitating
when I hammer the gas, so I'm thinking there is a fuel filter problem
also. If this comes down to changing the fuel filter, where is it? I
hope it is not in the tank. Any tips would be great, thanks.

The filter in on the firewall near the battery. Follow the line back from
the fuel rail. Be certain to support the filter with a wrench ( the filter
has wrench flats)and turn the fitting with a line wrench.
See if you have Sunoco gas in your area. Most of it is 10% ethanol and will
soak up water on it's own without needing to put in an additive.
Go to www.magnecor.com and read the tech bulletin on Mitsu. The plug wells
need to be maintained free of oil, mositure and crud.

Sounds like a classic ignition problem under load. You found one bad
wire for sure. The others are probably not much better. Do them next.

Thank you both for the info. After changing the plugs, I still had the
stutter at hard acceleration. Changed the wires, cylinder 1 was the
only one with the arcing hole, and no more stutter. Now, I just have
to work on the thumping noise on the right front to middle side during
highway acceleration. I do notice a thumping sound say when I hit a
bump on the right front side, guess I'll just have to get under there
and have a look.

Hey, on a side-note. Does anyone else have a problem with their
windshield washer fluid freezing up. I have used different brands of
"No-freeze fluid" with no luck. I think that having the fill resevoir
in the back away from the engine heat could be a design flaw. I poured
some rubbing alcohol in, so we'll see when the bitter cold hits NH
again.

I have the same problem. It is my understanding that it is the spray
nozzles that freeze up do to the alcohol evaporating out of the
solution. Adding a bit more alcohol should be an interesting
experiment. Please post the results when you observe them.
FWIW
YMMV
