Ok, couple of things here so bare with me:

1. I race alot on an 1/8th mile track, best time is 9.70 with a slipping clutch (SMOKED a Mustang GT with exhaust/header); I FRIED my clutch on that run (got JWT PP and OEM disk now) and I have HS Header, JWT ECU, JWT Gen 3 Cams, NO CAT (stainless 2 1/2" pipe), stock b pipe/exhaust (have greddy now, stainless from the head back, it's nice), Magnecor wires, NGK plugs, JWT POP, JWT mounts, Nitto NT555 Drag Radials, and typical suspension mods.

Since then, HORRIBLE gas mileage, stalling, and reduced performance. I replaced the O2 sensor and thoroughly cleaned the TB so it doesnt stall anymore and runs smoother but mileage is still not great (24-26mpg). THEN I noticed that when I checked cylinder #1, the plug was covered in rust red corrosion (just the white part of the plug) as was the plug wire inside and out. I cleaned it and replaced the plugs (all the others were fine) and it seems to be ok, I'm just still concerned (havent re-checked the mileage, I cant stop lead footing!). I've looked all over SE-R.net but nothing similar to my experience. Is it cross firing? I dunno...

2. I get a clicking noise from the right rear wheel. The strut and spring are brand new as is the wheel and tire. It only happens on robust bumps (like interstate bridge expansion slots or smooth, large dips in the road). It happens randomly on bumps at all speeds.

3. BOTH of my cv axles are new, but my right front wheel doesnt "feel" tight. Could that be the ball joints? My friend said they didnt look good.

4. Anyone in North Alabama with a fast Nissan or an SE-R?

Thanks for the Forum, J

try your egr, on your plugs, I would try to find the ngk site, I think that they have pics of all of the diffrent kind of plug pics and describle what is happening (like mine are charcoal colored, running lean) and since when did you start getting bad gas milege? when you installed something? and the clicking could just be.....wait......if they are coming from the same side, it probably is the ball joint that is bad. take off the hub and try to wiggle it around (or just see if the boot is ripped) this kind of stuff can happen when you put in cv joints, or springs, or anything that you do when you have to seperate it, looks kinda hard to replace, but easy with a few jacks and a sledgehammer :)

I started getting bad gas mileage about the time I last raced. Idle was bad and everything. I was running 103 octane gas so I replaced the O2 sensor afterwards which was a good move since I TORCHED it! Yesterday I cleaned my magnecors with denatured alcohol and man they were nasty! I've got some shitty Bosch +4's in there now cuz I'm waiting on new NGKs. We'll see what happens after these changes. I still dont feel that it's running great...

ya, I just found out yesterday how much performance you can loose from bad plugs.
