new poster here, but long time lurker. I have checked the forum for the question I am about to ask you and hove not seen anything with the exact same issues. I have a 2.9 that runs but it runs really rich. When i get on the gas it seems to run fine, but when i let off or try to maintain it bogs down and bucks. I have replaced the distributor and the ignition control module. When I first got the truck it sat for some time. It had a no start issue which ended up being the PIP sensor was bad. I Have also replaced the map sensor. This is an off road truck so the exhaust is cut off at the convertors. When I let off the gas there is sometimes a flame that comes out of the exhaust because it is running so rich. I have been told it might be the fuel pressure regulator. I was just wondering your guys opinion. Any and all help will be appreciated. Thank you in advance.
