I was gonna post this yesterday but wasn't quite sure, but after another day of driving I am sure something can't be right. Now this is onlywhen downshifting into second. Pretty much every time now, I go to down shift into second to go around a corner or something my car acts very weird. I downshift a little early cause I just got a new exhaust. Itwill bring theRPM's to about 2 grand maybe a little more and it will do fine untill it gets down to about1700 RPM's and below it starts to, I guess somewhat buck. It also squeeks, you know like when it gets really cold out and you juststart up the car and as you make your first roll it squeeks but then goes away when it getswarm. It is really hard to explain. It is kinda like I hit the brakes on and off really fast. I tried the same thing into third and it did fine, so I am almost positive that it is just second gear. Another way I could explain it is, it feels like she is starving for fuel.

For some extra info. Just got done changing oil and filter, fuel filter, antifreeze, PCV valve, and some lucas fuel injecter cleaner mixed with 93 octane. After all that it runs so nice and smooth except for that one issue. It also has brand new NGK plugs, taylor COP's.

Bump... no one know what this problem could be. Is it just me cause I expect my car to run as smooth as butter??
