Got my car back a week ago. Now codes 41 and 42
Do these codes in combination mean anything? the car seems like its running fine. the only thing is it bogs a little bit in o/d if you quicly let off the gas, but it stops after about 4 bumps. its a tpi 350 (crate motor) with a 700r4. thanks a lot guys, im a little worried cause i just spent a lot of time a money fixing this (the mechanic fixed it, not me).

well i read what the codes mean, but i was wondering more specifically what would need to be fixed if anything. i just got the car back and the mechanic replaced a bunch of distributor parts and spark plugs and reset the timing. could he have messed up somewhere?
