So I had the "privilege" of joining another forum about F150 to try to get some research done on my uncles 1986 F150 5.0 EFI that he bought new and garage keeps. The thing is just amazing for being a 30 year old daily driver. I needed some help with early Ford fuel injection as I simply didn't remember the ins and outs of it.

So long story short is after asking for help, I was be basically told I was an idiot and and didn't know what I was doing. On two separate posts. I was told I should get my facts straight before I post. Now I am asking for help, so if I knew everything I would be posting the questions.

After reading that I thought to myself wow, that would never happen over a squarebirds, I pretty much have seen a few idiots wander through here and still they are helped way better than I was on the other Forum.

So thanks for the help guys and great job. Happy to be a member here!!!

Ryan, you're always welcome here. As far as being an idiot, well, you're in good company because I don't know anyone who knows it all.

BTW, we also 'do' injectors. What is your question? - Dave

Message boards are only as good as the moderators who police them. This site is probably the best one I've seen to date.

sorry dave. My uncles truck has been around the block. Several mechanics have replaced endless parts. The emissions light is on and it runs like poo. Here is the symptoms.

starts and kills 2x's in the morning, back fires during acceleration and hesitates. for the first 5mphs then runs fine, starts hot very poorly.

actually I will copy and past my original post from the other forum. LOL I think I was pretty respectful. .

here it is

Good evening gentlemen, I am new here but a user of several other forums so I know new posts can be a pain from a first time poster, so sorry in advance.

So here we go. My uncle had a 1986 F150 EFI. He bought it new and it is garage kept to this day. I am very knowledgeable fellow about new Fords, but this old one is kicking my but.

First I have codes 12, 41, 25 and an emissions light is on.

Second the truck runs like poop and is backfiring on acceleration.

The list of parts he has changed is out of the box. It has a new distributor assembly, HP pump, tank switcher and new fuel tanks, new egr valve, position sensor, and evp solenoids. ( only part replaced by me so far ) and it did fix the egr code. It also has new IAC, TP and O2, which complicates the issues of some of the above codes.

The fuel pressure is at 39 running, but I have noticed if it sits over night I have to cycle the key twice to get it to come up to 35ish. It starts and kills twice every morning on cold start then runs. ok-ish

I have also sprayed down the intake to check for vacuum leaks. no difference.

once the truck has accelerated past 10 mph it runs fine. If just hates the acceleration from a stop.

The only modification is crane energizer cam during a rebuild about 2 years ago.

The timing is set 10 with the spout disconnected. ( not sure if should be different with the cam, so I just set it to factory setting)

So question is any ideas? I was going to go buy a new IAC to see if it clears code 12 and possibly a 20buck O2 again so I can do it myself to see if it effects the lean code. The knock sensor I am pretty sure will have to be a junkyard dog item as they are not available any where.

Thanks in advance and I will be back shortly.
