Ford 7.3L Power Stroke (1999-2003) :: 2000 - No Voltage At Plug When Brake Pedal Pressed?
Installed Tekonsha P3 on my 2000 F350 I used the recommend pig tail easy hookup when I press brake pedal no voltage at plug but when I move the manual lever I get voltage. I believe the stop light switch activates it. The fuses all check out. I did have a Banks engine brake installed by their people I don't know if makes a difference

If I could determine the resistance of the accelerator pedal at around 1000 rpms, couldn't I rig up that resistance and switch it on in the accelerator pedal circuit to make the truck go to high idle? Any flaws in my thinking?
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: No Throttle Response Stepped On Accelerator Pedal
I own a 2000 F250 7.3 Powerstroke 4x4. The only aftermarket engine modification I have is a Tymar intake. The problem I'm having started about 6 months ago in a very erratic fashion. I would pull up to a traffic signal and as the light changed to green, without warning the truck would have no throttle response. The engine was running fine; there was just no response as I stepped on the accelerator pedal. Usually when I put the transmission in neutral, revved the engine a few times, the throttle would come back on line. This happened 4 or 5 times over the summer and then went away completely until today. Today it came back with a vengeance. At one point I had to shut the engine down completely to restore throttle response. It's a bit unnerving when it happens in the middle of a busy intersection. I was told that it may be the throttle position sensor. Does this sound correct and does it need to be replaced?
View 14 RepliesFord 6.0L Power Stroke Diesel :: 2006 F350 - Accelerator Pedal Too Stiff
I have a 2006 F350 Crew Cab with the 6.0. It is used primarily for towing a fairly heavy 5th wheel RV. I find that the accelerator pedal pressure is much higher than any previous vehicle I have ever owned. The problem is magnified by the fact that I have a previous ankle injury that makes it very uncomfortable to have to press on the accelerator so hard for long periods of time.
I try to use the cruise, which sometimes works on flat ground, but the shift point at my desired cruising speed is such that the slightest grade will make it downshift. With the cruise off and my foot kept at a constant pressure, the truck pulls up the slight grades just fine with no significant loss of speed and no downshifting.
Is there any way to lighten the pressure it take to push down the accelerator? I know it is actually moving a throttle position sensor, but is there also a pedal return spring here that is too stiff for me?
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Intermittent Stalling At Acceleration
2001 f350. 7.3 has 350k on the engine. Last week it cut out and stalled it was about 15 degrees and though.. fuel had jeld... it warmed up.. didn't happen again. Then two night ago.. happened 4 times in a row then it was fine. yesterday a dozen times at least. It stalls but restarts itself (roll starting i guess) the water in fuel ,CEL and wait to start lights come on and then go off. We started with fuel filter, have changed the cam position sensor (yes with ford part not part stores) and now have also changed the Injection pressure sensor (also with ford part) while it needed changed as it was leaking oil the truck is Still stalling.
My dad is a technician He hooked his computer to the truck.. nothing. He was able to get the truck to recreate the problem with the scanner hooked up. When it stalls if he holds the throttle down the truck stays at an idle and the CEL, wait to start and water in fuel lights are on. It decelerates and puts along as nice as you please with the fuel peddle to the floor! let off the accelerator, lights go off and it recognizes the throttle again. No codes at all. hes thinking its the pcm telling the icp to shut off fuel. What would cause it to do that?

Ive got a 2011 Sonata GLS with 111k miles. I purchased the car new. For the past several months the brakes make a crunch or creaking sound when the pedal is being pressed OR released. The funny thing is it only happens when driving forward. When I apply the brakes while reversing, the brakes are silent. I did a pad slap at 68k and have taken everything apart, cleaned and re-lubed to no avail. The sound can be heard at the front wheels when someone else works the pedal while the car is parked. Pads have about 50% thickness. Pads? Calipers, master cylinder?
View 27 RepliesHonda - Accord :: 1999 - Engine Dies When Pedal Pressed Down / Revs And Then Quits When Pedal Is Pressed Slowly
Ok, did an intake manifold cleaning on my 99 Accord the other day, and now I have problems...
Long story short, some time ago my car started to have a very rough idle. Took me awhile to find the problem. Turned out the air hose, between the filter and throttle body, had developed a big hole on the underside. So I replaced it and while I was at it used some throttle body cleaner, spraying into the intake manifold chamber. Lot of junk blew out the tailpipe. The car ran much better, but the idle could still be a little rough. I ran it that way for awhile, and finally the other day decided there was probably still some junk in there and it was time to really clean it out. So I took ff the throttle body and intake manifold housing. There was a lot of junk in there! The small intake on the passenger side was completely clogged shut. (I understand this isn't surprising on these cars.) I used a bunch of rags and 2 cans of Valvoline throttle body cleaner and a lot of elbow grease and cleaned it out. I was thinking to myself that whatever I didn't get with the rags flushed through OK, but I didn't want to take the whole intake manifold out.
So I put it all back together. (I took a video before I started, so I'm pretty sure it's all back together right.) But now I have problems. The car starts. It idles fine mostly, but can be a bit rough. But the trouble starts when I put the pedal down. If I do it in Park, well, if I push it quick the engine just dies. If I push it slow, the engine revs then quits, revs and quits, over and over. Similar if it's in gear. If I push it hard, the engine stalls. If I push it gentle, it revs up, but chugs along a bit.
I've run some seafoam through it, thinking it was clogged up with all that junk, and sure enough, lots of smoke comes out, but nothing is improving so far. What have I done wrong?
Ford Super Duty (1999-2016) :: 2005 F350 Will Not Downshift With Pedal Pressed To Floor At Medium Speeds
Recently my F350 has failed to downshift when the accelerator pedal is pressed to the floor to speed up in traffic. It will usually happen when traveling at speeds in the 30's-40's. It will shift quickly at slower speeds. I have a scan guage on it all the time and it is not throwing any codes.
The transmission has only been serviced by the dealer; last done about 24000 miles ago. No leaks or low fluids/no burned smells. Stock setup with no heavy towing use. Currently at 228000+ miles, this is the first issue with the transmission assuming I am looking at the right area for the cause.

Golf VI R :: Clutch Pedal Vibrates When Accelerator Pressed
If I'm at part throttle and i press the clutch pedal in about 2-3 inches, leaving the clutch still fully engaged, i can feel a really rough vibration in the clutch pedal. it stops vibrating as soon as i let off the gas. and i'm only giving it a little bit of gas, mind you.
If I'm at idle, and i have the clutch depressed all the way and rev the engine, I can feel vibration in the clutch pedal. My 6-speed MK4 did not do this, not in the slightest. Is this normal for MK6 or do I have a problem?

What would cause me to lose accelerator pedal function after hitting a bump? The engine remains on, the CEL comes on and after a few seconds or shifting into neutral and back into drive I regain the accelerator again and the CEL goes out
The truck shows no codes. It is if some connection makes/breaks intermittently when I hit a rough pavement. Also, she sometimes won't shift in reverse. Could it be related?
Ford 7.3L Power Stroke (1999-2003) :: Accelerator Inoperative / No Dash Indicator Or O/D Lights
I have a buddy with a 1999 F250 W/7.3 TD. His property is accessed through a couple miles of hard terrain, so this may wind up being a loose ground or something that pulled loose.Anyway, the truck just all the sudden won't accelerate. It'll crank & idle all day long, but when you hit the gas.....nothing happens. I realize the diesel doesn't have an accelerator cable, as it is drive by wire. First thought was the APP sensor(accelerator), but most of the dash indicator, O/D, etc. lights are inop too.

2001 f250 7.3L, 289,000 miles, changed the IPR and ICP, noticed the EBP tube was in two pieces. Would this cause the rough idle and shaking? IT started running rough and would die after a mile or two. Would have to wait 30 minutes before it would start again. That is when a buddy told me to change the IPR and ICP the ICP plug was covered in oil as well as the top of the ICP. So I changed the wiring plug as well. I originally cleaned and changed O-rings on IPR but then it wouldn't start, bought a new IPR and started but runs rough. I just started it with EBP tube removed and sensor unplugged. Idling rough when I press accelerator and RPM go above 2K it levels off pouring black smoke everywhere.

So the truck has been stalling out and dropping power randomly, symptoms pointed to needing the 50 cent mod, changed the cps for cheap insurance and peace of mind just in case it wasn't the uvch, no dice. So last night I yanked valve covers for the first time here's what I did while I was under there, check my work.
1st I ohmed out injectors thru the 42pin harness according to tuglys sig link. My meter would only go down to a 0.4 when testing the test leads just to each other
DS injector ohms
#2 3.5
#4 3.4
#6 3.6
#8 3.6
PS injector ohms
#1 3.6
#3 3.6
#5 3.5
#7 3.6
DS glow plug ohms
#2 prong to ground 2" away 0.9 ; white connecting wire back to gp relay 0.3
#4 0.9 wire to relay 0.5
#6 infinity ohms up thru highest meter setting, checked multiple times and different ground spots,(replacing tonight) wire to relay 0.5
#8 0.5 wire to relay 0.5
PS glow plug ohms
#1 1.0 ; white wire back to relay 0.6
#3 infinity multiple tests as well (replacing tonight) wire to relay 0.5
#5 0.9 wire to relay 0.6
#7 1.0 wire to relay 0.7
Next up, ebp sensor was reading 1.9 higher than map/baro koeo, gently cleaning sensor earlier didn't work. Installed new motorcraft, will check it with Torque pro koeo once the batteries are reconnected
Next I checked the uvch connections which felt good, darn it, maybe a smidge of movement from the DS, but nothing halfway disconnected or anything. Hmm. I ground down the quarters to the top of his head and installed.
Next I torqued down the 4 bolts per cylinder of the rocker arms at 20 ft/lbs, all were perfect and snug
Next up, injector torque. I've read on here below 50, or 80 in/lbs depending on different threads and opinions that I would need to replace o-rings.
So I set the in/lb click torque wrench at 50 in/# and tested the wrench's click on the higher torqued rocker bolts, then checked all the injectors, all were good
Reset for 80in/lbs, tested, then hit all injectors, #6 almost budged but clicked immediately before the handle moved
Reset for 100 in/lb, tested on larger bolt, 2 injectors took a 1/8 turn;
Reset for official spec of 120 in/lb , tested wrench, all injectors took 1/3 to 1 full turn
Reset for 130 in/lb (above official spec, but highly recommended on here by those way more knowledgeable than me on our engines) tested on a larger bolt, slowly and carefully gave all injectors almost an extra 1/2 turn to click; whew, finally a relaxed sphincter.
At this point I knew I needed to buy 2 glow plugs today, replace, then I'll check all glow plug torque at 14 ft/lb in one go, so I got everything ready for a hot torque after I do glow plugs tonight ("unloaded" the torque wrenches) and finally installed the RiffRaff AIH delete plug. My cell phone's alarm went off to get the kids ready for school, so hit the snooze and got everything put up. Now for a nap, then buy 2 Motorcraft GP and check back on here before going back at it tonight.
I also checked the turbo for play in all directions, was nicely solid and spun smooth, no wheel damage. Up pipes and well basically everything exhaust under hood had zero signs of soot/leaks with inspection mirror.
Ford 6.0L Power Stroke Diesel :: 2004 Excursion - No Response When Step On Accelerator Pedal
i have a 04 ford excursion 6.0 with the egr delete, was stopped at a light to make a left turn, when i stepped on the accelerator pedal nothing happened as the engine was just idling. i pumped the pedal around 10 times and finally got the engine to rev up. i just got this excursion and don't know to much about the maintenance on it. i am going to drain the water and change the two fuel filters. my neighbor is familiar with diesel engines and he said to look at the throttle sensor. i have run this engine up to 900 miles and it has started and run perfectly. i believe the usual maintenance like oil changes etc were done on it. would any error codes show up even though no warning lights on the dash.

My "01 6 speed has started stalling after spooling down. Example, coming down a grade in a lower gear and then push the clutch in it will die. Where do I need to look? I've recently done injector o rings and normal service. No change at all. No other issues except a very touchy throttle. It's pretty disturbing to be pulling a heavy load, have to get in the brakes hard, push the clutch in and the engine dies. Not a good day.
