Hello, The car runs brutal when cold. Once she warms up, there seem to be no problems. I have a print out from my mechanic telling me what is wrong with my 1992 348 TS A couple of the notes along with the codes are as follows... Mass air flow sensor reads zero Catalytic conv. partly plugged right O2 sensor overheating. So, what I was thinking of doing is purchasing a mass air flow sensor and an o2 sensor first off. Then see how rough she runs to see if I need to replace the cat now (guess I would likely replace both at the same time??? if I'm doing one may as well do two!) Or, I know this isn't a nice thing to say, bash out the inside as we do not have pollution inspections. As we all know, if you buy parts through Ferrari, one needs to take out a loan so I see many of you have found a way to save a few nickles by buying through another source. When I do some searching for the sensors there are several to choose from even when one researches just Bosch stuff. Does anyone know the exact model-serial numbers of both sensors I should buy and where? Any pointers? I am relatively new to the game. Bought my 348 couple years back. Love it!!! Thanks folks!
