so i had my megan manifold and o2 housing installed today. Now for some reason, it feels like my gas pedal and clutch are stiffer?? it doesnt drive the same at all?? even shifting gears feels different. this is gonna sound crazy, but the only way i can describe the shifting is if there were like clay in between each gears. its not really really bad, but its just different. And i dont really see how a new manifold and o2 housing would make my clutch feel stiffer, my gas pedal stiffer and my shifts feel different.

any suggestions guys. its been a really bad weekend for my car. not to mention i just found out that my brothers girlfriend backed into my car in the driveway, denting my hood and scratching the hell outta my bumper.

any ideas??

thanks

ps. my car is only tuned for the mods in my sig. i havent been retuned for the manifold and o2

 

get it tuned and then see what happens.......other than that i dont think i can help too much......i will be installing my ported polished mani and o2 here soon

 

help

 

Go look at the car, there's no way installing these items should affect shifting at all. You must have something stuck in the way of the shifter arms or something, and maybe kinked the throttle cable (check where it comes out of the firewall into the engine bay.

Double check your work, that's all it can be!
