Problem after visiting the dealer

[Breino]

Hello a little background I have a4 b7 I have a gfb dv, fmic, intake, test pipe, all have about 10k miles on it. Last week I was looking into getting a stage 2+ tune so I bought a hpfp rebuild kit I went to the dealer to but a cam follower to change it... Car has 93k miles I took it out and surprise the cam follower was missing the top and my hpfp was pretty messed up and my cam had bad scaring so I found a dealer to replace it under Warrenty they did it but they saw that my timing chain tensioner was crack so they replaced it and they also said that a sensor above the cam went bad so they replaced that( cost $400) so I went drove it home fine but when I hit the gas(wot) it missed fired bad sounded kinda tough but ran terrible check engine light blinked then stayed on i scanned it and it said misfire #3 so I pulled the plugs and they where all mismatch and only 2 where the ones I put in and the other two the gap was .80ish I bought new plugs still missed #3 I moved the coil packs around still #3 the packs are 45k miles old.... Any ideas what could be wrong? Sorry for the essay

Check the wiring make sure it's not jacked up and maybe switch #3 injector to see if it follows that.

Do you think the dealer might have done something sketchy?

[Biged243]

On purpose, I doubt it. Could be just poor mechanic skills to sloppy work. Until you pin point it you wouldn't be able to tell/speculate what happened.

lol yeah just swap your fsi injector its easy , do you have the new Teflon seal and install kit ?
Biged243 - are you a tech ?

op - take it back to the dealer - it might be mis-timed when they installed the new intake cam.
also not to be a dick but its kinda hard to follow what your saying , use punctuation. you cant use "and" that many times in 1 sentence .

I have not seen any bad wiring on any b7 to date at the dealer so i highly doubt that's it .

Lol yea my fault I was typing as I was thinking about the story my bad..... I will try to swap the injectors... I have never done that before.
I guess I'll call the service department tomorrow and see what they say.

Since it happened as you were driving home from the dealership, I think it's clear that they likely caused the issue. I'd give them a call and explain what happened and the timeline (in coherent english).

It could be something as simple as them forgetting to plug in the Cylinder #3 injector.

Lol no I am not a tech. Why are you asking?

I agree with Hayden. You picked it up and had these issues driving home. As soon as it happened, I would've called them up and made them fix it as soon as it was limped/towed back over there. It could a simple connector; it could be something much worse. Thing is, get them to own up to it since you obviously drove it there fine. And be polite--that usually helps get things resolved quicker.

Thank you audibot for not busting my chops.... I took my car back to the dealer after a day of test they said it was a bad injector. They said it was going to cost 1100 dollars to fix it, I told them not to fix it I will pick it up on Tuesday. I went to pick it up and as I was driving home I turned the ac on, nothing but hot air came out. I went back and I kinda lost it on the service manager :/ they looked at it and said they accidentally bump the connector and it got loose. I took my keys and will never be back.

A buddy and I are going to take it all apart, clean out the carbon and replace my injectors Hopfully that will fix the problem
