Dude I highly doubt your scanner isn't accurate. It's hard to fuck something up like a scan tool.
Why are you even worried about a rust proofing appointment for the car when it isn't even running right? Did they do a leak down test? Did they do any further testing other than just putting a coil in?
This is what they told me "he needs your tuner so he can put it back to a stock tune and go from there. Unfortunately thats not going to happen for any time soon. Were looking at least 2 weeks if not 3 weeks from now"
this is what they did, connected their scanner detected misfire on cylinder 4 and asked me if i had changed coils yet, they bought a new coil it didn't fix the problem. uh oh we don't have time for a problem like this tell him to come back in 3 weeks
Thats all they did replace the coil and my car was there since Thursday
I asked them if they could just swap the coils between cylinders to see if the misfire would move and they said "Its a pain in the ass to take the intercooler off well just buy a new one" this kinda pissed me off. My uncle got me the appointment so they squeezed me in I understand it's busy but they didn't really try to fix it. They didn't charge me anything thank god
But yeah still no leak down as no time, i think im just going to buy one
So now I wait for my usual garage to see me December 2 and hopefully we can figure it out
Something that's kind of concerning me is when I did my compression test cylinder 4 was weak but I kept getting different readings and then the guy that did a comp test last got 150+/- and he also comp tested it when i had him do a PPI and it was 160+/-
