While they may have made improvements- just like everything else on the planet- Doesn't dismiss that i've always liked the fox better than that geo storm copy SN95 body style. Just my opinion...RELAX

Always wanted a fox since high school, now that i'm 40 I think Ive payed my dues. Finally got what I've wanted, just trying to enjoy the finer things in life...my 90 GT. If others have questions, isn't that what this forum is all about?

wiring was one major improvement, as was the accessory design, brake systems, and uni-body strength

I see, very interesting. Thanks for the info, I have a friend that just bought a 93 lx, thats why i was so curious.

only problem i've ever encountered for a rough idle is MAF jacked up or unplugged, or intake gasket leak [throttle body to upper, upper to lower, or lower to heads] if it's not that it's one of the sensors, either IAC, MAF, or TPS. if it's none of that.. well... it has to be one of those. make sure your quadruple check them. it really sounds like MAF or gasket leak. make sure everything is plugged in all the way, and all the prongs are clean.
