Throttle control? from failsafe mode??

[firefighter253]

first, thank you guys for the work you put into this site..I have been able to save so much money and time with the info posted here. I need some good advice on this one, heres the story..

2005 LS with 65,000, already had 4 COP replaced under the lincoln recall.. Car starts acting up exactly like it did before, only differance is it threw itself into failsafe a couple times. Off to the dealership I go.. Now they are saying its a thottle body error thats they "traced" to an accelerator pedal assembly?! I do know (thanks to this site) about the COP #4 causing thottle body error codes..So my initial reaction is the dealership if full of sh*& as it pertains to tracing it back to accelerator pedal.. I have had no issues with the pedal not responding or sticking.. only issues have been the occassional "bucking" from COP failure we are all so used too. I questioned dealership about if they stress tested all the COP's and of course thier answer was a crappy attitude and yes they did.

So...anyone else in the world had to replace accelerator pedal assembly from 400 bucks or so even though you have no accelerator problems??????

the DBW/ETC can cause a bucking which COULD be construed as a coil issue.

I would not take any chances when it comes to ETC/DBW cars, if the dealership is telling you it's messed up.. you probably should replace it.

Because.. if you dont, and your it malfunctions and you go WOT and crash, the dealership has their azz covered.

Drive by wire is scary stuff....is your life worth 400.00?


Now, with that said....you need to be clear with them.
If this doesnt solve the issue then they shouldn't charge you to "throw parts" at an issue.

I'm not saying just go "bend over" at the dealership, though... you shouldn't have to pay for their technicians to practice installing parts.

you need to be talk to the service manager, dont be a dyckhead to him.
Tell you you want to put your trust and faith in their dealership and diagnosis.but you do not want to sponsor a fishing expedition.

If the issue is pointing to a #4 coil misfire, it'd be cheaper to replace THAT coil.
I wonder if the issue is "they dont want to warranty the #4 coil again, and would rather make you PAY to replace something else."

Just pour some oil into all of the coil sockets and take it to another dealership. This is what I would do if I was under 100k. I would definitely not trust them that is for sure.

yea i mean this is a scary one.. great point about the DTW on this car, esp with everything going on with the toyota's. i just got off phone with dealership and they are confirming they are "100%" sure this is the issue.. They did the previous recall work for me and even contacted lincoln to confirm they recall was ongoing until the 10 year 100,000 mile so i guess i may have to put a little faith in thier work... I at least feel slightly better that some one on here is confirming to a point that the bucking could be the throttle

Also, they confirmed they tested all coils and they came back normal...for what thats worth

They don't cover 2004-2005 for oil leaks, only the 2003.

The electronic throttle design has tons of failsafes to prevent a run-away car (you can always shift to neutral anyway). The failure mode is no power, not full power, so I wouldn't be concerned about this being a safety issue.

If you can change the coils yourself, I would at least swap the #4 and #5 coils before paying for the pedal assembly. If the swap makes failsafe mode go away, then you know it was the #4 coil. If not, it could be another coil, or it could be the pedal or the throttle body. Did they tell you the exact code(s) that were stored? We could give better advice if they were known.

and pray they dont compare the nice clean oil around the coils to the likely dirty oil on the dipstick....lol
potential MAJOR fail

It doesn't matter. On a 2004, VCG oil leaks are not covered. If they find oil in the plug wells, all repairs will be at your expense, oil in the wells invalidates the 100K extended coil coverage on 2004 and 2005. He would be doing the exact opposite of what he should do.

100% agreed, if there 100% sure that is the problem, then they need to pay 100% of it, if it turns out to not be the problem

If you can change the coils yourself, I would at least swap the #4 and #5 coils before paying for the pedal assembly. If the swap makes failsafe mode go away, then you know it was the #4 coil. If not, it could be another coil, or it could be the pedal or the throttle body. Did they tell you the exact code(s) that were stored? We could give better advice if they were known.

i started to get the ETC failsafe mode warning and a slight hesitation just one day out of the blue, 4 or 5 times in a half hour, swapped coils 1 and 4 and the failsafe warning never came back, the hesitation was still there and i replaced the coil and no problems since

and pray they dont compare the nice clean oil around the coils to the likely dirty oil on the dipstick....lol

thats why you need to drain a little oil out of the motor for that

lol, my idea is still the best. shadyness + failness.

w00t

there have been several instances of "runaway" occurring in the new mustangs when the cars are modified and make more torque than the pcm is expecting to see.
