Car is acting up When I drive it feels like the car is missing or bucking a little. I just replaced the plugs and wires, air filter, cleaned maf, changed tranny fluid and diff fluid. I had a scan done and the o2's and injectors are working as they should be. Any help is greatly appreciated. Car is an m6 by the way.

No I haven't driven through any water recently. I'm beginning to wonder if it could be a drivetrain problem. My rear wines pretty good but I don't know if it could make it do that or not.
Try to get a friends/relatives or someones MAF and swap it in and see if it runs any better. Cleaning it will only help if it is dirty, not if it is actually bad (which is fairly common on these motors).
Does it do it all the time or is it hit or miss? I'm assuming no codes are being thrown?

I haven't had time to check anything yet but I was paying more attention to it on my drive to work this morning and it seems like it only does it while maintaining a constant slow speed.
what would/should happen if you leave the maf unplugged? ie how to tell if its bad? not to hijack, but... i have same thing going on, also throwing it out here check the pcv system

Having the same problem. It is fine while cold but once the engine warms up it gets worse. Seems to be most apparent when leaving a stop sign or when at WOT. Just recently replaced my EGR valve thinking that was the problem. New o2 sensors aswell. still same thing. My car is also catless.
