I have a 1984 Econoline with a 351 with auto trans.

Going down the road after warm-up the van will stumble & stall at any speed. However, when I pull to the side of the road and put it in park it will run smooth and accelerate from 800 rpm up to 2200 rpm without a miss.

New fuel tank, new fuel pump, fresh fuel and just tuned it up.

Any ideas?

Thanks,

T.W.

 

 

It was my understanding that the Ford Truck Enthusiast forums were to assist Ford truck and van owners in the best use, maintenance and improvement of the Ford truck or van that they own. This would include member assistance concerning operational issues that affect the running or performance of the truck or van of a forum member.

I didn't realize it was a platform for criticizing a member for trying to get assistance for a problem with their Ford truck or van by making smart remarks. I was not aware that this forum had a special way to ask for assistance.

Since that seems to be the case, I will refrain from using this forum for any information I need or any comments that may assist another forum member.

And I will let the moderators of this site know how well their site is working.

 

 

Dang Mjac167, the brake booster is the only one I didn't check. I sprayed around the base of the carb and plugged all the other vac. lines. I'll try that one and hope it takes care of it. Thanks man for the help on this. I'll update you once I find out the problem.

 

 

With the engine running, spray a flammable liquid (like WD-40 or similar, but not starting fluid) around any place where there could be a vacuum leak. Use short bursts, and move along vacuum hoses, manifold gaskets, etc. Use some clear tubing if needed for tight spots. When you spray where the leak is, the liquid will be sucked in and you'll hear the RPM change.

Obviously, be very careful. You could start a fire. That said, this is a tried and proven method for fining a vacuum leak.

Now, about that meme.....

You posted your question on the 23rd. You received no response until the 28th when I posted. That's 5 days of being ignored. Was that good for you?

There is a direct cause and effect relationship between your thread title and the lack of response you got.

When you post on a forum - any forum - you are competing for attention. If your title gives the wrong message, you won't get the attention of the people who can help you. A title that states the problem clearly gets the best response. A title like yours often conveys someone who is lazy and expects to be spoon fed. People who have been around forums a while (who are usually the people who can help you) tend to go right past titles like yours. For one thing, they are scanning for places they can help. That's why they are here. So, people who are good at electrical problems tend to jump onto threads about electrical problems. People who are good with brakes jump on threads about brakes, and so on.

Who is attracted to a title that says nothing more than, "Help"? Social workers, maybe, or psychologists? Life guards? Certainly NOT people who know about Ford brake systems or differentials.

When you post a request for help on a forum you are asking for people to give their time and expertise to you. In return, you are expected to put in some effort in describing your problem in a way that makes it easy to help you. That starts with your thread title.

Now you can get your panties in a bunch, or you can learn a valuable lesson. Your choice.

 

 

Well, if you know what you are doing, yes, but the volatility that makes it more effective also makes it more dangerous, so that has to be balanced against the advantages. I never recommend ether unless I know the person has got sense enough to use it safely.

 

 

 

 

 

I posted Help! in the THREAD TITLE by the way because I needed help and the following area below that is for explaining the problem. I didn't realize that this was an advertising forum. Very plain, simple and to the point.

And I don't see how the thread title could be annoying. I guess anyone who thinks that is as simple as the thread title.

Like I said in my previous post, I'll delete this from my bookmarks because I sure wouldn't want to hurt anyone's sensibilities about how a thread is titled.

Thanks to Mjac167 for being the first sane forum member to answer my post. I appreciate the help Mjac167. Maybe I'll catch you on one of the other Ford forums.
