car won't start with mass sensor plugged in

Question

I have a 95 Thunderbird 4.6 car won't start with mass sensor plugged in but once I unplug it car starts right up but dies out after 10 to 15 seconds or so... Is this normal.... What might it be????

Answer 1

HI there

This usually means the maf sensor needs to be replaced. Either that or you have a large vacuum leak on the intake AFTER the mass air flow. If the sensor isn't delivering the right info, then the computer will not make the proper mixture. Also, check your air filter. It might be plugged.
