I'm working on a 1987 Ford F150 that's cutting out at speeds above 45mph. The ignition system and fuel pressure checks out OK, but it still cuts out at speed. Today I noticed a new symptom and a rather bizarre one at that. If you slam a door or hood, the engine speeds up 500 rpm and then settles back down.
View 2 RepliesI have an '03 Ford F150 with the Triton motor. About 2 weeks ago it started acting like the motor was "cutting out". We changed fuel filters, got a fresh full service, got the alternator checked and did visual on the drive line and rear end ( did have a mechanic check it also). The "check engine" light does not come on while it is acting up (it does light when starting so I know the light works). At first the truck only acted up when it was good and warmed up, but now does it all the time.

I've replaced coil, distributor assembly, plugs, wires, throttle body, checked timing etc. I've got spark through the plugs and fuel in the cylinder but with no luck. Don't know where to turn next.
View 3 RepliesThe truck will not get up and go. When you step on the gas it cuts out and acts like it is going to die. When you give it a lot of gas in idle it also makes a popping sound. When I first tried to figure out what was wrong the catalytic converter got red hot, so I took it to a muffler shop. They said it was not the cc. They then put a new distributer cap on it and an EGR sensor. Still does not run right. The following is what I have put new on it since:
Spark plugs and wires
EGR Valve Throttle position sensor
Fuel filter Fuel Pressure Regulator
Took it to another muffler shop again they said it was not the cc and did a throttle body clean out. I have put fuel injecter cleaner in the gas. When there was a gauge on the fuel pressure regulator, the fuel pressure did not go above 30 PSI and when you stepped on the gas, the gauge read between 10 and 5. Also it does this more so when driving rather than idle and especially when you have to give it gas (like going up a hill) and it seems to hesitate more so after being warmed up. The fuel pump is working according the the ASE master mechanic that tested it with his gauges.
I have a 1987 ford F150 302 we were ran off the road and went over a side walk. When we came to a stop the truck cut off. The truck was towed back home and have been unable to crank it since then. We have checked the inertia switch, checked the firing, and changed plugs in it. The trucks will turn over but won't crank.

View 2 RepliesI'd like to convert my power steering to manual. I've done this to my Mustang, but never a vehicle this long and heavy. Looking for impressions of the results. Also, any special tools that may be required for the swap.
My truck is a 1987 F-150 4x2 extended-cab long-bed with a 351w and C6.
1987 f150 302 4spd 4x4. When I bought the truck 4 years and 12K miles ago the orig owner had just installed a new front pump (in tank) and new switch thing on the frame rail. He said shortly after that the rear pump stopped working so he just ran off of the front tank. That's what I've been doing also except as of the last few months it has started to leak from the rear tank (I don't ever put gas in it and was empty when I bought it) and dies periodically from time to time? Where the leak could be coming from. I do suspect the dying has to do with the leak though.
View 3 RepliesI have a 1987 ford f150 with a EFI throttle bodied 5.0L (302), and I have taken it to a mechanic multiple times because for one it has a dead spot in the throttle and it dies when you let off the gas at a stop light or sign. But the mechanic said he checked everything he knew to check and found nothing wrong with it. I also had my cousin read the computer previous to this and we couldn't pull the codes from it.
View 2 RepliesHave a 2002 Yukon 5.3 ltr engine (155K miles) that likes to cut off at highway speeds. Usually happens after 4 or 5 hours of running at 70 to 80 mph. Strangely if I set the cruise control and do the same speeds, nothing... When it happens I end up coasting to the side at the roadway and sitting there for 15 or 20 minutes and it'll start right up and usually go the rest of the way. I've talked to a couple repair shops and they have checked service bulletins and have never been able to find anything. Will be driving to Connecticut for the 4th and not looking forward to being on 95 with the possibility of this happening again.
View 2 RepliesWhy the frame mounted fuel pump might run after the key is turned off? Then when you turn the key on it may or not run. If it does run it keeps running. shouldn't this shut off after pressurizing the line? is their a pressure switch in the pump that's failing? This has the 3 pump system...
View 4 RepliesI have an 87 F150 4x4 4.9L EFI with a single tank. Fuel pumps keep running even when the key is off. I tried swapping relays but the problem still exists. The engine will start and run OK for about 15 secs. then die. I installed a new low pressure pump, high pressure pump seems to be OK. I also installed new fuel filters. I dont want to just throw parts at this truck, where do I go from here?
View 4 RepliesLooking for a wiring diagram for a F-150 XLT LARIAT 5.8L 4BBL, all the books I have looked at show the wiring for this year with fuel injection and this truck came with a 351W with a Holley 600 4BBL, I have a few wire's in the engine compartment that melted away all the insulation, they are located close to where the harness passes the firewall before the ignition module. Is this a common problem on old models ?. Need a clear copy of the correct diagram for a f-150 1987 with carburetor, how I can get a copy so I can fix this problem before it gets worse.
View 3 RepliesInitially I brought the car in for repair because the engine was cuting out at higher speeds so they replaced all 4 coil packs and did an oil change.
After 50+miles of driving it was taken home. Later on we tried to start the car and it wouldn't start. The car has power and it cranks.
We then bring it back to the shop and they say there is no compression. I suspect conventional oil was used.
Would the wrong oil cause my problems? 2008 VW Passat Turbo...
A few months ago my car started whining at highway speeds. The noise has increased in pitch and volume, and is not dependent on engine speed--in fact, if I turn the engine off and coast, the whine persists, lowering in pitch (and getting quieter) when the car slows down. Recently the car has also started vibrating when I turn slightly to the right, as when I change lanes on the highway or bank right on a long turn (sharp right turns from a full stop don't elicit any noise). Do I have a problem with my alignment? I notice my tire wear looks a bit uneven.
View 4 RepliesI have 140,000 miles on my 2005 F-150 and for the past year I have noticed a somewhat high-pitch whistle or howling sound coming from either the front or underneath. The pitch and volume continuously varies as though it is just tire howl, but I just changed all four tires and no results. It gets much louder at about 65 mph and 78 mph, but I don't hardly hear it at any other speed. My brother says it's just a wind whistle, but I strongly disagree as it doesn't change when i drive against or with a strong wind. I rely on this pickup for work and can't afford to be without it for more than a day or two, so, for peace of mind at least, I would like to know what is making the sound.
View 6 RepliesToday I was backing my ex up in my yard(down hill) and it acted like it was going to cut off. So put it in drive and it would not go,so I thought low in fluid. So I checked it, it was fine. So I tried it in drive down the hill and its fine. So confused as I was I tried in reverse again and it done it again. Any clues to why? Its a 03 v10 with 76xxx miles...
View 14 RepliesI have a 1987 Ranger 2wd, 2.9, 5sp that feels like it is cutting out when accelerating. The only code in the computer (KOEO) is 67, which according to the manual is neutral drive switch (NDS) circuit open. What to look for? Can the neutral drive switch be the problem?
View 14 RepliesI have a 2000 Ex V10 4x4 that I use as a daily driver and also haul with it(4 horse trailer loaded). The brakes are not cutting it, they suck. The rotors have been turned 3x in a year and it is due for pads and I am sure rotors now.
I want to upgrade so that I don't continue to keep having this amount of problems. Sadly the beast gets abused with 3 teen drivers at the moment, so I am pretty sure that is contributing to the eating of brakes.
My 1992 AeroStar 3.0L 2WD keeps cutting out like it's not getting fuel BUT...only after around 55 mph and after it warms up.
I first thought it was the fuel pump so I changed it. I didn't get a whole sending unit along with pump, I just dropped the tank and changed the pump...that didn't do the trick. Then I checked the fuel filter along the bottom rail and it's very clear flowing. Then I thought it might be the fuel pressure regulator. Ok, how many of you have changed the fuel pressure regulator? Man it was tough! I had to grind down an allen wrench to get room to turn those three allen bolts AND I replaced it while I was stranded on the side of the road!
Well, replacing that regulator didn't work either. I don't know where to go from here. It totally cuts out at higher speeds when it's warmed up. Could it be the oxygen sensor? It can't be the plugs. I don't think it can be the sending unit in the tank even though I changed its pump. Is there another fuel filter somewhere? I'm moving to another town and I have to get the van there.
I have a 2005 EX Eddie Bauer. In the past week the climate control system has acted funny twice. Once on startup it did not turn on and once while driving it just turned off - as in digital readout is blank and the unit acting as if it has no power. It seems to "fix" itself... What I should be prepared for - bad unit or something else?
