f150 HELP!
OK I am stumped and dont know what step to take next. I just filled it up with gas and went 17 miles then went to the store. Then put it in drive and it dies. SO I replaced the IAC that didnt work.. I unpluged the MAF sensor still did it. But it idles fine! And if you rev it up above 1500 rpms and put it into gear it wont die. Then if you let off the gas put it into park then back in reverse it wont die. Or drive. SO any suggestions onto checking next? Btw it is 4x2 with the 4.6

how does it run after you get it moving again? How many miles are on this?
could be many things....start simple.
change the fuel filter and check for vacuum leaks...& considering you just filled up...you might have gotten a bad tank of gas
