Hey Everyone,
I have a 99 Porsche Boxster with 64K miles. The performance has gotten pretty bad, and the check engine light came on, so I took her to a mechanic someone recommended. They said the mass airflow sensor is reading -40, the mechanic hooked up a new one (Bosch), and the temp was still -40. There was also a code that coil 3 misfired. I am guessing the two are related (maybe the low temperature reading is causing her to run rich). But if it is not the MAS, I am stumped.
I ran a search in here and on Google with no results. Anyone seen this before?
Thanks,
Jonny
