Yesterday My car threw 4 codes; 0400,0402,0171, 0174.
0400 and 0402 are EGR (comes up about every week cause i have no EGR...)
0171 and 0174 are banks 1 and 2 running lean. (never had that code before)
Car was running fine when the codes came up but started running weak (limp mode i believe). After i cleared the codes the car started doing this...

Any help would be great, I'm thinking air leak maybe...

OH, p.s. the brakes have nothing to do with it. I was pressing the brakes because there was a car in front of me... just clarifying.
