Ford - F150 :: 2006 - Clunking Noise Under Mild Acceleration At 40 - 50 MPH?
I have a 2006 F150 with about 80k miles. It has a limited slip rear end. Under mild acceleration, "sometimes" there is a muted clunk at about 40-50mph. If I accelerate harder it does not happen. I cannot get it to happen at lower speeds. I cannot tell if its the transmission or rear end.

I have an '07 with 122k miles. There is an issue with the car when I attempt moderate to hard acceleration. I have observed the following behaviors:If I hit the gas hard, the engine will suddenly cut out, almost as if it hit the rev limiter or VSC has kicked in. The engine does not die, it just appears to go back to idle. It is not a miss or stumble. It is a full loss of engine power. If I keep my foot on the gas, it will kick in and out, sometimes so suddenly that it will chirp the tires when it re-engages. It will do this until I let off the gas and accelerate more slowly. It seems to happen when the car starts to pull hard over 3k rpm.
It can happen in any gear, as I have tried playing with keeping it in 1st, 2nd, or 3rd, and have observed the same behavior when I hit the gas hard. It is not pedal position dependent, as I have observed this at anywhere between half throttle and wide open. There are no lights when this occurs. I have held it in this state for almost 20 seconds at times, trying to get a CEL, but nothing happens. I have hooked up a TIS tech stream monitor, and there are no problems recorded. The car runs and idles perfectly aside from this problem. If I accelerate normally, it will run just fine. It almost seems like a fuel delivery problem. Could the pump be suspect, not allowing enough fuel during high demand?

Ford F-150 - 1997-2003 :: Medium To Heavy Knocking Under Light To Medium Load
I have been getting some knocking the under most any loads . I do not have any codes. I tried premium gas and that did not make any difference. If this is not fixed what issues can this cause? What should I look for do get this fixed?

Once I had driven for about 15 minutes and the truck set for about 5 minutes. Then it would not start. Another time, I drove for about 20 minutes and it cut off while driving in a parking lot. I have had 2 different shops take a look at it and they cannot duplicate the problem. They have run a bunch of diagnostics and tried their selves but it always starts for them.
View 2 RepliesFord Fuel System :: 1988 F150 - Cuts Out Under Load?
My 88 F150 (300 six, 5 speed, dual tanks, 176,000 miles). The truck has the low pressure fuel pumps in the tanks and the high pressure pump on the frame rail setup. Truck starts fine, but cuts out severely under acceleration for the first 30 seconds of driving. After that I only notice the problem when applying a lot of throttle (does not cut out under gradual acceleration) or climbing steeper hills. If I kill it for a few minutes and then take off again the problem is back for the first 30 seconds or so. I have replaced all the tune-up type stuff (all filters, plugs & wires, dist. cap & rotor, ignition coil, o2 sensor, cleaned throttle body, replaced IAC valve, numerous sensors). Timing is dead on at 10 deg. BTDC with SPOUT unplugged. My FPR was bad so I also replaced that. Condition exists regardless of which fuel tank I am using (no problems with tank selector).
Getting no KOEO codes, but getting KOER code 41 and plugs do seem to show a lean condition possibly. I'm still averaging around 16 MPG since this became a real problem about 3 months ago.
I removed the bowl from the reservoir between the tanks and the high pressure pump on the frame. No filter in there, but it was clean with no gunk or sediment found. I removed the line from the inlet side of the high pressure pump and found that while cranking the engine I have fuel flowing freely (same amount of flow regardless of which tank I've switched to). The flow was steady, but not extremely strong. If I understand right the in-tank pumps are not designed to provide much pressure? Below is what I found at the schrader valve:
key on, engine off - high pressure pumps runs for about 1 second, brings gauge up to 48 psi
idle, FPR connected - 40 psi
idle FPR disconnected - 52 psi
revving throttle with FPR connected - 46 psi maximum
Connector, where fuel pump relay plugs in, seems to be clean and not corroded at all.
Ford 6.0L Power Stroke Diesel :: Runs And Starts Perfect But Under Medium To Hard Acceleration It Bucks / Sputters
Starts good cold and hot. Taking off like a grandpa on an evening drive don't notice a thing. Only codes that keep coming up are 2614 and 2617 which are cmp and ckp open curcuit codes and a software incompatibility code for FICM which is due to the updated software in the fresh FICM I installed. HPO pressures are good, has boost, idles smooth, revs nice when in park. New injectors (cause it was running rough especially cold before) and CMP and CKP (because of the above codes and didn't change)and ICP and IPR (last 2 installed because of HPO codes that are gone now with the IPR and ICP). Fuel pressure is 65psi (updated spring). When you step on it while driving it sputters and bucks like it's out of fuel, let off the throttle a bit and it purrs like a kitten. I'm a little stumped. I think it puffs a little white/blue smoke while it bucks.. not much tho. and it comes in little puffs. Took off filler cap and there is almost no blow by.

I have a 2004 F-150 crewcab, 4.6L with 118,000. I don't drive the truck often but for the past few months its stalls and cuts off, and idles poorly in reverse. Truck cutting off at low RPM's, low speeds, and after going over some bumps. At one point the engine light came on but now it is off and I am still having the issues. . . . not sure what code it would display. I have been reading articles and blogs and most say the TPS, MAF, or IAC is the problem.

I have noticed since day 1 of owning my v8, that there i a horrible sound that comes from the exhaust upon medium to heavy acceleration - a loud fluttering is the best way i can describe it. I took it to the dealer and one tech said something was definitely wrong, the other went and got a new reg off the showroom floor and demonstrated that it is common and normal. Although another new reg did the same thing, i am not convinced that this obnoxious sound is normal ...
View 17 RepliesFord Wiring/Electrical :: 1996 F150 - AC Runs And Then Cuts Out / Compressor Not Turning
Have and intermittent condition with my 1996 F-150 4.9. AC runs and then cuts out (compressor not turning). I lose 12v to both side of high side switch. I tried to troubleshoot using a schematic in Haynes Foprd Pickups and Bronco for 92 and later F-Series/Bronco, but the color code for the wiring doesn't match up.
On my truck, there is 2 wires from the low side pressure switch which mates to a socket with only 1 wire. I have 12 volts at switch terminal on dash control, and it seems that I have an broken wire behind the dash, as I can get it to operate again when I move the harness around. Where can I get a schematic of this part of the circuit?
Ford Wiring/Electrical :: 2000 F150 - Power Cuts Out When Attempting To Start
2000 XLT F150 4.6 - New starter & solenoid(s), battery cable & fuse links good.
When i turn the key, I hear one single click and the power cuts out entirely. I can't attempt a second start or turn on the lights or have any power going through the truck until I disconnect the battery for about 10 seconds then reconnect. Electrical becomes live again, then when the ignition is turned the electrical cuts out again. I do hear a single cluck at the starter (probably attempting to engage when it cuts out) and a clunk right at the inside fuse box (drivers side).
Lexus LS 2007+ :: LS460L - Lag Or Stutter During Medium To Hard Acceleration
I have a 2007 LS460L. Bought it new and have loved it dearly for 6 years now. It now has 70k miles and is under an extended warranty purchased at 50k miles. As a first year model it has had a ton of TSBs done on it.
The problem i have had as long as i can remember is a lag or stutter during medium to hard acceleration. It feels a little like the old turbo lag or like a very mild stutter. It has had the transmission adjusted, had the service manager driver it for a week to try and capture on computer etc. But nothing has fixed it. At times it feels like if you watch the tachometer during these moments you can actually see a bounce (I may be imagining).
I have almost given up and just lived with it. We have tried tranny, type of oil, software tweaks etc.
Ford - Taurus :: 1995 SE Cuts Out On Acceleration
My 1995 Taurus SE check engine comes on shortly after starting, cuts out for two seconds on rapid acceleration, and the check engine lights goes off for ten seconds. I replaced the distributor cap and rotor, the spark plugs, and the air filter. I have tried Techron injector cleaner. It is better but the check engine light is still on and it cuts out as before.
View 19 RepliesAccent MC (2006-11) :: Engine Shakes For Two Seconds Then Cuts Off When Reversing
My 2007 Hyundai will randomly after being parked for 3+ hours will stall (engine shakes for two seconds then cuts off) when attempting to reverse. This only happens when the car is turned on then trying to reverse. It will NOT do this when driving and later putting the vehicle into reverse. Additionally when the weather is extremely cold or hot this becomes more frequent. If the car can be shifted into reverse without stalling within 5 seconds it will NOT stall. To solve the problem I have to either keep trying to turn on the car and shifting to reverse until it doesn't stall out (sometimes 3 tries or more) or putting the car into neutral and pushing. I have to stress this only happens after having the vehicle sit for more than several hours even a day and is random. One day no matter how many times I tried turning the car on and trying to reverse and repeating it would not stop stalling out. I had to wait till the parallel parked car in front of me moved so I could get out of my spot. What is wrong with my car? I have taken it to Porter Hyundai TWICE and they cannot determine the problem even after scanning for codes.
View 1 RepliesToyota - Tacoma :: 2006 - Gauges On Dash Die And Engine Cuts Out
All the gauges on the dash will die for a second and the engine cuts out and the car jerks then it will come back on and everything is fine. Sometimes the gauges turn off completely and the car will die and will not start for several minutes. I will try to start the engine but it will not start until the dash lights come back on. The first time this happened to me I changed the air filter and the car ran fine for a month. So when it happened again I took my air filter out put it back in and again the car worked fine for a couple of weeks. Now, It doesn't work to mess with the air filter at all. The car is cutting out more and more.

Just installed my SCT livewire TS. The truck runs good without a tune but it has egr delete so it had check engine light. So I put a performance tune with egr disabled so it cleared code. But I noticed at pretty heavy acceleration the fuel seems to cut out. Usually once boost builds. Does the same with the street tune.
View 5 RepliesPrius (Gen 2) :: 2006 Engine Runs Briefly And Cuts Out / Oil Overfill Caused Complete Shutdown
I went to a local oil change place on Tuesday morning for an oil change. Had them change the air filter (engine and cabin) at the same time. The odometer is at about 165k on my 2006 base model Prius. When the job was completed and I pushed the power button, Christmas tree. Giant red triangle of death, check engine, and the display picture with the "!" in the middle. Can't put it into gear. Engine runs briefly and cuts out. Maybe they tripped a wire when they changed the filter? Nope, all was good there. Silly little tech put it on his code reading machine to no avail.
I called the local Toyota dealership that I hate and don't use and they gave the oil change guy instructions to jump it. No dice. So I leave it in the bay and call a tow truck. Towing guy figures out how to get it into neutral and puts it on his truck to take to local hated dealership (mistake). Long day of fighting with oil change place, followed by super star service from larger dealership in Austin (60 miles away) with the service rep I always use. He diagnosed the likely problem over the phone. I didn't even let local hated dealership do the diagnostics. I put that little Prius baby on a flatbed and took her to Austin.
Well, the codes pulled were P0A0F (engine failed to start) and P3190 (poor engine power). Well, that is the magic combination along with the experience of my service rep and tech to confirm that too much oil was added. It's was about a half of a quart. Crazy, right? Well, they cleaned the throttle body, interior of intake manifold of oil residue and all is well again. The big battery was completely dead so the dealership charged it up for me.
Next morning I pick it up and big battery is charged about halfway. Not sure if they completely charged it the night before. However, by the time I got to work (maybe 5 miles), battery indicator was full (green). I had an oddity when I had a longer stop light idle later that afternoon where the battery went from 4 blue bars down to purple, but drove the 60 miles back home and today the charge seems to be fine (4-5 blue bars). I have a sneaking suspicion that there may be more issues, but for now all is well. I'm going to get the 12V battery changed soon because we're still riding on the original.

(When Car Cuts off...You can Crank it right up...No Problem...Began to accelerate and Cut off.. Start it...and go..Decide to Press Gas Down and ride the Clutch and Gas While Shifting and car Stays Cranked but I look like a Rookie Behind the Wheel and will Burn out My Clutch..So.. After I stopped and raised the Hood....I took the Negative Post Off...and Car Shut Off.. Bought a New Alternator...BAM...That's The Problem.. NOT!!..
4 Days later...Start out the parking lot...Car Cuts off..Same Problems All over again.. I took the Alternator to be checked..Fine..I took the Battery to be Checked and charged..Fine.. What Could Cause the Car To Cut Off after I hit 20 + Miles and Up..between Shifts....it Dies..? I need to Get to My New Job..and It's my only Means of Transportation...

I have a 2009 V6 Ltd with about 15k miles. It has always seemed to shift a little too hard from 1st to 2nd and from 2nd to 3rd under light to medium throttle. Does this sound like a transmission ill that can be fixed by adjustments?
