Trouble Codes
 

I drive a 2004 mazda 3 hatch with the 2.3l engine in it. Im currently recieving 4 codes from my ultragauge sensor and need some help on what i should do about them.

p2178
p2188
p2196
u0155

I've had the MAF sensor replaced twice already which is clearly not the solution. I also read the bulletin for the faulty ground wiring to the MAF and want to know if i should get the replaced and if so, where i should get it done. Thanks for any advice you guys can give.

search the forum... there are a couple posts that talk about these codes.
here's one post

I don't know much about this stuff but try checking http://www.jcwhitney.com they have a lot of stuffs there for auto. I had purchase accessories for my car there. They have too many techy stuffs starting from the exterior, interior even up to cleaning products for your car.
