Re: Weird Problem
I have a problem that started right after my wife filled up a few weeks ago. This is a 1992 B350 with the 360 FI engine.
When it warms up and you are traveling with very minimum acceleration it will "cough" just almost like a backfire through the carb. In fact that pretty much describes it. If you floor it the van takes off like a scared rabbit. I thought it would start failing when I took up a steep hill.....just goes great but if you are going 25mph and ever so slightly start to speed up it will do it's cough. I checked everything but the fuel filter because I have been told it is in the gas tank.
Would a clogged filter do this? I thought it might be water in the tank but I've added some additive that is suppose to clear that up and it still does it's cough. No engine codes. Doesn't do it all the time and at 70mph for two tank fulls it only did it trying to get up to 70 and then ran without a hickup until I had to stop again for more fuel.
Any ideas?
