Ford F-150 (2004-2008) :: Slight Delay When Press Down The Pedal And Acceleration Actually Happens
Aug 28, 2015
I've been noticing over the past couple years that sometimes when I accelerate, there's a slight delay between the time I press my foot down on the pedal and when acceleration actually happens. From reading other threads it would seem that the most common fix is to re-flash the ECU. I bought a DiabloSport Predator tuner along with a CAI a while back to improve performance/gas mileage and I was wondering if there's a way I can use the tuner to re-flash.
If not, do most ford repair shops already carry these? I don't want to buy a flash programmer. Also, if the shop does carry this type of an item, what is the average cost to get it re-flashed?
I own an '04 F150 XLT 5.4l.

I have a 2004 F150 4.6L... There is a slight hissing sound under the dash on the drivers side when you lightly press the accelerator and then stops. No matter what speed you are going as soon as you apply the accelerator it hisses then stops. There is also the same hissing , only louder when the engine is cut off. It hisses for about 3 seconds. What could be causing this. It has been idling rough since the hissing started. The check engine light is on and showing P0420 and P0430 codes . The cats were replaced with resonators so I believe that is the reason for the codes.

I am a first time owner of a 2015 VW Golf TSI and TDI, previously drove an Acura RSX.
I am noticing on both cars, more so in the TSI, that off a dead stop, when I push the gas pedal there is a hesitation/acceleration delay that I am not used to.
Is this normal? I just want to make sure that nothing is wrong with my cars as I am not well versed in this stuff.
Also, if it is normal, what is the cause behind this? and can it be modified to remove this lag?

It just started doing it the only way I can seem to figure out how to explain it is at about 50 to 60 under slight acceleration or uphill it bucks or jerks like you have a trailer jerking. No check engine light this thing is driving me nuts... 2004 f150 5.4 ...

At 89,000 miles I replaced my plugs with autzone autolites and also replaced my fuel filter. Shortly there after the truck started to shutter and shake while miss firing giving a 0307 code. After checking that plug and replacing it, moving the COPs across the engine from each other the miss firing continued under the 0307 code. The miss firing mostly occurred when I was around 50 MPH, under slight strain with a little acceleration. If I powered through it most of the time it would clear out. Occasionally it was bad enough to where I had to pull over.
I trouble shot this for about a month before it got more consistent and worse. I took it to the shop where they tested the compression on the cylinder and also tested each coil. All check out OK. They recommended I replace all plugs with motorcrafts and the boots on the coils. In the process of doing that I discovered a loose plug in the #2 cylinder. I pulled it out and found that it was scorched and the metal was slightly tweaked at the tip. Not sure how it got loose or how it got burned, but figured that I found the problem. All plugs and boots replaced!
Two days later more miss firing. This time with a 0305 code. Occurs again on a grade at around 50 MPH with slight acceleration. I pulled that plug and the plug in the cylinder where the loose plug was found. Nothing seemed to be wrong. The plugs seemed a little brown where I put anti seize on but that I figured was normal. I then moved coils again. The miss fire continued and the code did not move. There is still a rough idle and occasional humming coming from the engine.
Is the loose burnt plug a separate issue or is there something causing all the miss fires that backed my plug out. I'm lost on my next step to take. Im getting married in two weeks so needless to say spending more and more money on this issue let alone time is making things so stressful. Besides the fact that I think my engine going to blow up on me every time it miss fires bad.

I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.

I am having a minor problem with my 05 F150 Lariat. Under light acceleration going up a slight grade the truck sometimes shudders (vibrates?). If I let off the gas or accelerate slightly it stops. At first I thought it was a feedback loop with the electronic throttle so I had the dealer reflash the computer but that didn't fix it. I've noticed that it happens right about the time the torque converter locks (looking at the tach) and I'm sure it has something to do with torque converter locking up and then disengaging continuously. Funny thing, it seems to happen frequently on the same hill at the same speed. What was done to fix it?

For the past day and a half, when i start my car there isn't the usual smooth, quiet sound of the engine starting. There's a slight delay, and a whirring noise. When i put the car into gear and accelerate, the noise increases in volume and pitch. I think it might be something with the power steering pump or a belt issue, but I'm not fluent in Car and Driver speak.

So I've been finding myself lately having to press the ebrake pedal pretty deep when parking on a non leveled surface. Went to the dealer and they said this car has self adjusting parking brake........ Is this true? Do I have to suck it up? If no, how do I adjust either the pedal or the parking brake bands?

I have a 2002 Passat 1.8L T AWM Manual, 223K
I have noticed in the last little while, The car has a aplit second delay when I press the gas and it pulls.
I.e. If I'm on the highway, 5th gear 110km.h, I let go of the gas, soon as I press it again, a split second delay and it pulls with a slight jerk( Gas....... slight jerk. accel no problem).
Also, at times when the car is sitting overnight, my Airpump doesn't start when I start the car. In warmer weather, it always fires up after the car has been OFF for a period of time.
I got my Ross-Tech Vag and scanned it with no issues, except, my ABS module is not communicating.

I bought my 2005 f150 three years ago and the auto headlights never worked. I have just turned them on manually. Couple weeks ago they started to delay coming on and now they do not work at all. All other lights work including fog lights.

I have an automatic 2004 f150 fx4 with a 5.4 engine. I just bought the truck and noticed the other day that when I shift into reverse, there is a 1-2 second delay. Sometimes it will shift quicker than other times. Drive seems to be a little more swift I think. Everything seems to run smooth and the shifting is very smoot other than the delay. Is this normal or what could be some of the causes. The previous owner has the ATF changed this pst summer and it looks and smells fine other than maybe having to much fluid.

I've got an 04' F150 and the ONLY problem I have with it is a ridiculously sluggish throttle. I bought the Superchips Tuner in hopes of eliminating this, but the delay in the throttle is still there (power is much better however). When I talk delay, I am talking hitting the gas and probably a realistic .5-1 sec delay. It is quite annoying to say the least.
My question...is there something that I can do myself to improve the throttle response? I drove an older 150..probably an 02 or 03 and it felt sooooo much more powerful just do to the throttle. I am even willing to ditch the Superchips if the Ford re-tune would do a better job.

The timer built into the Prius needs to be pressed each time a delay is needed ? Is this correct ?

Picked up the car 5 days ago but noticed when I press the clutch and rev the engine, there's a throttle delay/hesitation and a simultaneous sound like "psshht". The sound is almost like when you're shifting a turbo car with a blow off valve.
Other than that the car is great. 2012 Elantra GL manual ...

I can press on the brake pedal when car is off or on and there is a kind of quirky sound made. I can hear a pump sound and then a squeaking or quirky sound. It happens every time I press the pedal when it is stopped, either on or off.

I've a UK 2004 gen ii with 69000 miles on the clock. When coming to a stop and also when at a stand still if I press down the brake pedal I get a rather loud creaking sort of noise. I guess that's friction brake related as no noise with using brakes when driving. Also a high pitch squeal when driving and turning steering wheel slightly to the left that stops when you press the brake pedal.

My truck has 112,000 miles on it and I have been having a slight delay in the transmission from 1st to 2nd. The switch is easily felt but, it's not a hard clunk when it engages. After that there's no problem. Additionally, when I switch to reverse it can take a full second to feel it engage before I give it gas. The transmission fluid looks fine and the levels are fine, too. Have not had a flush done and but I was thinking about changing the fluids and seal.Also, wanted to ask about my rear suspension. The leaf springs have lost a bit of their spring and was wondering if those "add a leaf" kits are worth it. The truck rides level but any loads in the bed cause it to really sag. I put new shocks in which improved the quality but the concern is just the leafs.

I have a 2007 Toyota Prius. When I press the brake pedal and press the start button the engine does not start or the wheels are not powered by the battery. It gives me the following errors:
The indicator in the Start button lights in Amber Color.
0 kmph mark is not activated in the dash board pannel.
When I shift the gears it only shifts to neutral ("N") gear.
I cant move the car forward or backward. An error message is displayed in the MFD in Japanese language. It is in Japanese and I cant read the error message.
