I have a 1999 F250 Super Duty With the triton V10.
It just out of the blue started having a hard time idleing. When i start it, it bounches between 400 and 1300 rpms. It surges really bad. When I drive it and I slow down to a stop or turn it wants to die out. Also when I am at an intersection it is a little better in park than in gear. I can't put it in reverse without it killing and then have to gas it to move.
I went to Autozone to have them read the codes and it said my MAF sensor was bad. I changed that out along with a new air filter while I was in there and it still does the same thing.
What should I try next? TPS, IAC? Anyone else have this issue in the past? I hate to have to keep buying parts that don't fix the problem.
