My Avalon began idling rough for a few days before driving it on the highway and while driving, it stalled never starting again. The fuel pump has been replaced, alternator and starter tested fine however, when I stepped on the gas, the start up attempts were better.
Any suggestions would greatly help at this point, thanks

P1100 indicates a problem with the MAF sensor circuit:

Did you install an OEM fuel pump? Tested pressure at the fuel rail?
Also, see the troubleshooting section of the FAQ.
