Random stalling? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

My 92 Grand Marquis which otherwise runs/drives fine, seems to be having issues at stoplights. It'll start to idle rough, the battery light will flash a bit, then it'll stop running. Also, it sometimes seems to be having trouble accelerating between about 60km/h and 80km/h. Any ideas? I know it's had its fuel pump replaced with an inline fuel pump, and it's not at every stoplight although it's more often now than before.

Has the intank pump been removed in the process? How is all of this set up? I'm not familiar with anything like that so whoever did it may be able to help there. Try cleaning the MAF with MAF cleaner and chlean the IAC.

Forgive me for my ignorance, I know MAF is mass air flow, but what does IAC mean?

Idle air control. Don't feel ignorant, nobody knows it all.

I'm not sure what the deal with the fuel pump is either, sorry I didn't do that work I bought the car with that already done.
