#1320 of 2180 Re: vibration in my 2004 F150 super crew 4x4 [tadrag]
Jul 14, 2005 (5:22 pm)
I too experienced the same thing Tom did with his vibrating truck. Mine is an 04 F-150, 5.3L, 19,000 Miles . I have both types of the vibration that is going around. I have the 48-58 MPH constant finger tingle vibration from the steering wheel. It has been back to the dealer 4 times for this type(balanced tires, rotated driveshaft, added counter-balance weight, etc.). No improvement yet. Vibration is worse under load.
The second vibration is the insidious one as it is intermittent. First appeared in Jan of 05. Very cold day so I forgave it. Two months later it does it again. No check engine light or codes found by the service dept when returned with description of mysterious vibration. It comes on at odd times and lasts for about 2-3 miles. When I stop the truck and shut it off and restart it the problem goes away. It is starting to do it about once a week. I think this truck is going back to Ford. No problems with the dealership or service as they are trying to fix this truck. I can't fault them because they did not design or build this vehicle, Ford did.
If anyone else has this type of problem please post it so that we can find out how wide spread this is.

Thanks I'll check out the lines again, I looked them over and don't see any that looked cracked or broken. It's got a pretty simple vacuum system. That's whats got me stumped. There are 2 solenoids in the vacuum diagram called air D and air B, Do you know what these are?

The hose is a vent hose to prevent pressure buildup that happens as the diff lube expands from heat. The hose will mount to the body or frame above the diff as high as possible with enough flex room for full suspension movement, check for blockage (hose, nipple) also disconnect from diff connection, run a wire thru far enough to make sure there is no blockage. I use a small tie wrap around the hose at the diff fitting for a good seal at the diff. The valve at the top of the hose keeps water from entering if you are forging a creek/river, check that also. Should allow air out, nothing in. Blockage in the vent will cause diff lube to leak thru the outer seals, soak the brake material, must be replaced. Hope this helps. Woot
#1324 of 2180 Re: F150 very engine runs rough when driving-smooths out at accel or downshift. [kross]

Dam that's a tuff one, I fixed 10 of them. 5.8 or 5.0 doesn't matter. Is the idle smooth or sometimes rough? Lots of problems with EGR valves sticking open somewhat, vacume pump can check that, remove and clean, or just remove the vacume line, while the idle is smooth, plug the vacume feed line, tell me if there is a difference. There is also specific routing patern for ignition wires. Hope this helps, Woot

wpalkowski Thanks a bunch You were right. The vacuum hose going through the firewall to the vacuum valve that closes when you go to max air was rotten inside the plastic wire holder. I was able to pull it through and replace it. It took care of the problem Thanks again Tom
#1326 of 2180 Short in Fuel System
Jul 15, 2005 (7:30 pm)
I have had my 1999 F-250 in the local Ford dealership for a week now and they cannot figure out what is wrong with my truck. The symtoms are: Running realing rough as if the engine were about to stall due to flooding, smoke from the tail pipe with a rich smell of fuel not being efficiently burned. The dealer has identified he beleives it is some type of short and has been on the phone with the tech reps from ford with no luck so far. Any ideas?? I bought this truck used and I currently live in Lousiana but the truck came from Canada and had the heater coil plug in for cold weather. Thanks

Sometimes the simple stuff will make you nuts.
#1328 of 2180 1986 F150 spewing fuel
Jul 16, 2005 (6:25 am)
I hope someone can help me with a problem my hubby and I are having. We just (yesterday) had our '86 F150 tested for the Ontario Drive Clean Emmisions, and it took the mechanic most of the day to get it to pass, on the curb-side idle CO2 test. To do this, he had to play around with the carb and get the fuel mixture so lean, the poor truck didn't have any power! Legally, he wasn't allowed to change the settings afterwards, but he showed us how to readjust the carb, which we started working on. Took it for a drive last night, and it still needed a bit more adjusting. So this morning, hubby inspected the fuel filter and put it back on, everything looked fine. Adjusted the mixture a bit more, then he took it around the block for a test drive. Didn't make it to the end of the street! The carb was leaking fuel at the base, and spewing fuel from the top! Also, it was noticed that the gasket from the air filter compartment was missing after we picked up our truck, and we thought it might somehow have accidently fallen in, but we can't see it in the carb... Any suggestions?

Sometimes, a hammer will solve the worlds problems. Turns out the float was stuck, and a few light taps with a hammer loosened it up, and the truck is running fine again. Next question: how do I prevent this from happening again? Will I need to take the carb apart and do something with the float, or should I just make sure there is always a hammer available in the truck?
