2.9L flooding ..HELP!!
Alright, this thing is an 88 B2 with the 2.9L. It will be running fine and then all of a sudden start acting like it's flooding out and wont go away. but if you turn the truck off then back on, it will quit doing it. The problem may start again or not, but turning it off and back on will always fix it. Now it doesnt just do it when it's hot or cold, it does it whenever it wants to. It has a new fuel pressure regulator, air filter, fuel pump, fuel screen. HELP PLEASE.

2.9L flooding ..HELP!!
I also have a 88 Bronco II Eddie edition and ever since we baught it
it has been flooding driving down the highway or in the city. Black
smoke comes out the exhaust when it happens. We have had it to several mechanics also, we have had everything from the exhaust replaced to the map. when we changed the map recently this made it worse. I thought that maybe it could be the fuel regulator but being a mechanical part with a diaphram it would cause it to do it all of the time. Also checked the air fuel mixture sensor at the front of the intake as it is not a throttle body but the resistance is even all the way across range. So if you ever find out what it is Please post it here on site as it abviously is not just a problem to our truck.

2.9L flooding ..HELP!!
my 86 b2 2.9 did this aswell. what fixed it for me was a new dist and ignition modual. give that a shot if you can and that should help it. but first just pull our the dist and see if its got any play. if it does and its easy to turn crap it and replace it. 30 mins max. if its in good shape take your ignition module off (need a special tool from auto zone for this) and run it to auto zone and let them check it. if its not bad i dont know what to tell you other than to look at a computer change out. it could aslo be a dirty mannifold (intake) witch it partly my prob. if so just take a clean rag and whipe it out but you must remove the throtel body acording to ford but i dont mess around with it for the most part. as for the intake runners. youll need a like a giant felxible qtip to clean them without removing the intake and heads. or you could take your coil wire loose and put in some carb cleaner but i think your better off to swab it out.

I have 89 Bronco II and went thru the same problems and it was the fuel regulator. It did not happen all the time. Pull the vacum hose to the regulator & if there is any gas in that line you need to replace it.
