Okay. My car was misfiring. My car has had a recent tune up replaced O2 sensor and mass air flow sensor. Brought it to a tech and is still misfiring in the rain. What could this be? A friend, after a quick look, thinks he saw a possible crack in the distributor box. Could this be it. It is not too severe, but I need an inspection sticker. Oddly enough right after the tune up and replacement of parts, Car failed inspection only for emmisions. Since I brought it to inspection almost immediately after the repair shop, I am not even sure if the problem was fixed to begin with. Spent over $2K in repairs and don't know what to do. I would get rid of it, but I still owe alot on it.

Misfiring when it rain is an indication of bad wires and or bad coil and need to be checked.
Have to check for DTC codes

Okay, now it is still misfiring, but it is giving code P0135. Entire exhaust was already replaced and Mass Air flow sensor, O2 sensor 131117? After I drive and get out of the car, it smells like something is burning.

Okay, So you think problem may be a bad O2 sensor like technician said. I already had 1 replaced and mass air flow sensor too. Does that narrow it down to only a few? How many are there on this car?
