Ford Fuel System :: Flat Spot When Accelerating Off Idle
I have a 4160 on a 351 Ford. I confess, it's a boat!
I had a major flat spot when accelerating off idle. I found it wasn't pumping on the accelerator circuit.
I replaced the accelerator diaphragm and cleaned the squirts and the passages. It squirts great now, but if I floor it, it completely bogs. If I baby it really carefully, once the engine gets over about 1800 rpms, it acts fine.
I thought it over, checked the travel on the arm that presses the diaphragm, and figured my pump cam was worn. It "seemed" like the duration of the squirt was not long enough.
I got a new cam kit. The orange cam on my carb was not a bit worn compared to the cam in the kit. Not encouraging. I put the only other cam in the kit that I thought might work. It was blue, and it gave more lift but no greater duration. It did not make any difference that I can tell. Is there a transition circuit I might have problem with? I don't know enough to go any further.
Ford Fuel System :: 1984 F150 - Truck Absolutely Will Not Idle
I have a 1984 Ford F-150 with an I6 engine and a motorcraft carburetor. The truck absolutely will not idle. So I got to looking at the carburetor, and found this red hose going from the carb to a metal pipe, the pipe was just dangling there not connected to anything, and the end it rusted off. I'm pretty sure I know where the other end is supposed to go to, I just don't know how to get there as obviously I am missing some parts and I can't find them so they must have been lost on the road somewhere.
Here's how it looks:
The end of the pipe:
Where it is supposed to end (I think)???

My truck is a 1990 Ford F150. It seems like when I let it sit for a few min that the gas just drains back into the tank and there for it wont start up that fast, it takes a while to get it going but when I shut it off and start it back up its like a new truck. It starts right up!!! Any tips on what might be wrong, maybe the gas cap is letting pressure out? Im 17 and my dad knows alot about trucks but he cant tell whats wrong.
View 1 RepliesFord Fuel System :: Truck Starts Choking And Stalls After 10 Minutes Or So Of Driving
My truck starts and runs fine cold. after 10 minutes or so of driving, it starts choking and stalls. If you try to start it, it will not. If you wait about 3 minutes, it is fine, starts , and drives ok, for about 3 minutes. I have replaced, plugs, fuel filter, battery, and a ignition module, as well as cleaned the opening of the throttle body
Ford has ordered a fuel pump, I am thinking it could be the
-Throttle position Sensor?
-MAF sensor?
-fuel pump?
It puts out code p0191 for low fuel pressure. Ford is scheduled to install new pump in am, but I don't want to spend a grand if it is just the TPS or MAf?
Ford Fuel System :: 1982 Truck - 2150 Power Valve Cover Replacement
Well I have a 2150 carb on my '82 truck, I looked in my parts and illustration guide and found what should be a fairly close overhaul kit for my truck based off it being a non high altitude truck and it has A/C and its a 302 with C6 transmission 2 wheel drive.
Down side is the power valve that came with my kit is a two stage power valve and I currently have a single stage power valve.
If I were to use this two stage power valve where would I buy a replacement two stage power valve cover?
Ive been looking but cant find any anywhere and I am to the point of figuring out what power valve my truck has currently so I don't have to put my only vehicle down for multiple days for a simple carb rebuild.

I have a 92 f150 w 302 . My front tank leaks out of the gas cap and builds up pressure. Even though I have never put fuel in it (owned it 7 mos). I siphon fuel out of it weekly. If I switch from rear to front. The truck stalls out.

1991 F150XLT, 5.0, E4OD....Should the EFI system bump up the idle speed when the AC system is operating to compensate for the compressor load? Obviously I'm asking because mine sure doesn't. With AC on, the idle speed will drop to around 300rpm in Drive, like when sitting at a red light for example. Surely this isn't normal operation...is it?
View 4 RepliesFord Excursion :: Idle Between 900 - 1200 MPH Normal?
So here's my problem; my 05 Excursion has a v10 and now it does not idle correctly. At a stop sign and in gear it idles anywhere between 900 to 1200 rpms. Normally it should be idling around 750. I just noticed this as I had to apply more brake pressure to keep from driving through an intersection. Since this has happened I have changed the air filter and fuel filter. Do you think I need a computer reset, or something else?

I rebuilt a 1963 ford 2B crburetor with manual choke. Put the carburetor on and it runs very rough. Won't go below 800 rpm or it dies and I need to choke it to start. Thought it was a vacumn leak so sprayed WD -40 and no change in idle. So pulled off the carburetor and put on the previous carburetor (with electric choke) and it runs great. I want to use the manual choke to hook up the cable though. I replaced everything in the carb. What do you think it is?

View 6 RepliesFord Fuel System :: 1978 F150 - Idle Drop Down And Stall
I have an ambient temp switch connected to the vac port on my throttle emissions control solenoid for my 2150 carburetor. It's a 78 F-150 with a 5.0L 302, automatic 2WD. Would a bad ambient temp switch screw up my idle? I've disconnected the vac hose and it won't idle at all, and it does the same thing when I disconnect the two wires from the ambient temp switch. If I leave everything alone, I can get the idle down to around 1800rpm, but any lower than that and it stalls.
Is it possible to swap out this throttle emissions control solenoid with another type? I've looked everywhere and can't find an exact replacement, and I have no instructions on how to tune it.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 - Battery Light On When Truck Is Running At Less Than About 1200 RPM
Battery light comes on when the truck is running at less than about 1200rpm, but I see zero movement on the needle. Weird thing is i charged the batteries and tested the alternator with my multimeter and it was reading 14.1-14.2 which is nominal. Run it for about 10 min then it reads 12.3-12.8
I'm thinking a bad cell in the battery or alternator is going out. Oh and all the connections are tight, wires look good. 2001 f250 4wd 7.3 intake exhaust basic tuner gauges. Could the constant heat be a factor?
