Ahh ok I am no genius at auto mechanics so bear with me but would not lower mpg mean I am running RICH not LEAN?

running richer would use more fuel would it not? ie from your site

"Simply increasing the base fuel pressure will make the engine run more rich at lower boost, and will hurt your fuel economy slightly"

I do believe I have a Fuel Pressure gauge but I thought it said it can't be used on Fuel Injected cars. I will check this weekend.

I also thought the injector controlled the pressure of each squirt ultimately? ie the Metro uses a recirculating fuel system it just cycles from the tank to the engine and back to the tank and the injector "takes" what it needs for each pulse.

Hmm I did not realize I could just use a coil off another car.

They are cross compatible? I have to snatch a new coil for my cherokee (puked on me yesterday at least I HOPE thats the problem I get no spark from the coil) so I can grap another coil when I go get the cherokee coil.

what could would you suggest as hotter and compatible?

I thought it was expensive because when I looked up aftermarket ignition systems well the sticker shock took my breath away :-)
