Ron,

Based upon similar performance and pinging symptoms with a '94 TBird,
I'd suggest you investigate the condition of your MAF sensor. These
frequently develop a coating over time and cause incorrect information
to be sent to the computer regarding the volume of air being passed to
the throttle body. Consequently, my car ran in a constant lean
condition which caused detonation and substandard performance. The gas
milage drop could be unrelated, or it could be caused by having your
foot in it more than normal. Sometimes they can be cleaned with carb
spray and/or electrical contact spray cleaner (in any case, don't touch
the wire - its very fragile). Didn't help in my case (I put in a new
sensor and it runs great now), but others on this and the performance
list have reported that cleaning did help.

The TBird has OBD-II, which allows a direct read on the air volume being
reported. Your Xploder doesn't have OBD-II, and I'm not sure if it is
possible to read the MAF - does anyone reading this know? (Tim?)

> Since I don't usually drive my wife's 94 Explorer much, it takes me awhile to notice any changes in it. Well it seems to me that it is running kind of sluggish, especially on the hills here in PA. We use to get about 22 mpg on a trip with it, but last weekend, we took a trip and only came up with 18 mpgs! In the past, we had problems with it pinging, so I think I may have over did it with injector cleaner trying to get rid of carbon build-up. My gut feeling is that the sluggish performance and drop in gas mileage may be due to plugged up catalytic converters because of over use of injector cleaners. My question is, is there any way to test for a defective cat converter other than just replacing it? Thanks for any help!

Make sure the wiring to the tank is good before you replace the pump. I replaced mine first and could have saved myself
the trouble if I had checked the wiring carefully. There was power in the line as indicated by my test light , but the
wires were so badly corroded that they couldn't pass enough current to run the pump. On my in-laws B II, they had the
same symptoms, but it turned out the pin the wire connects to on the tank was broken off.

To remove the tank, pull off the skid plate, remove the wires carefully and remove the tank straps. I used a trolley
jack with a piece of wood on it to support the tank without denting it. I found LOTS of penetrating oil helped and be
careful of the metric bolts. I can't remember if the skid plate was inch or not, but the tank straps were 10 mm.
