Probably so.

#8 fails because of the coolant flow being restricted. Yes it runs hotter but the coolant getting stuck their does it in. Trading your car in and making it someone else's problem is pretty fucked. The dealer isn't gonna fix it and whoever buys that car is gonna get shafted. Says alot about you.

Also a re-tune is needed for cat deletes unless the check engine light annoys you. The cot only happens on decel.

From all I've read (and I'm no expert just spent a lot of time reading) most of the issues with #8 were traced back to two things:

1. Tuners in the very beginning not knowing what they were doing and changing the pcm to cause lean conditions and altering knock sensors.
2. A bad batch of PCMs seemingly put on cars that were built in the middle of 2011. I believe the particular pcm code was: ZFK0

Im sure after today Travis will tell me there is a pcm code showing : FUK'D lol

**Soulowd** · 02-06-2014, 06:16 PM

ok fellas just got back from GH and Travis said it passed the leak down test with flying colors and he said he drove it and he said the car drives great! I asked him why AF ratio was off so much per TS he said they were either doing something wrong or the JBA headers have been known to throw the AF off. Regardless he said leave it with me and he will Dyno tune it tomorrow and he will fix it but he said there is nothing wrong with the car. So, thats what I did. He is dyno tuning the car tomorrow

I didn't mean a trouble code...but a particular code ON the pcm.

**GTOphil** · 02-06-2014, 06:52 PM

See that's the kind of thing that worries me...I have NO clue where to take my car when I want to get it dyno tuned.

Some say GH, some say TSM and other have other people they "swear" by. I'd like to take it to my friend's shop but I don't know his Ford guy...plus I know his dyno is notoriously 15-20 low and as much as you "shouldn't" care about dynos it still makes my pee-pee hurt, lol.

**Soulowd** · 02-06-2014, 07:24 PM

i here you on that GTO...I mean you saw i was about ready to take a bath and sell a perfectlt good running 5.0 with great miles. Glad Travis came through

**DirtyD** · 02-06-2014, 08:23 PM

Awesome to hear! Glad that Travis checked everything out, and hopefully you will have a good tune after it's done.

Was TS doing a tail pipe sniffer during the initial dyno pull? If so, that may be one of the problems why it was reading low.

This car came in for a tune, we did a base line just like all cars get before we build our custom tune. On the base line pull the car was 15.1 AFR from 2500rpms to 4100rpms so we aborted the run. Checked the data log and it also show 15.1 AFR. Advised the customer that we were uncomfortable tuning the car at this time since we felt the motor might be hurt or will be hurt soon since the car has been run this lean. Coyote motors that see heat of 15.1 AFR for any length of time will have a very good chance of the number 8 problems very soon. We choose not to be a part of it,

Good luck and hope you beat the odds

Tim

By no means was I dogging TS at all. If you look above I said, "Those guys are standup guys." I appreciate you guys concern and appreciate you telling me your opinions...However, I literally was about to return this thing to stock and take a bath on it not to deal with this issue. I was Telling GH's to return it to stock and Travis said that he wanted to do a leak down test to see if it was infact hurt at all. He said it passed the leaked down with flying colors and he drove it as well with no issues. Soooooo....

Glad too hear it, and I promise you if we felt different we would be happy to have tuned your car. We have a different option on what could happen,

Good luck my friend

Now it makes sense. Just because it passed the leak down test doesn't mean that there hasn't been damage to weaken the cyl already.

let me ask this...Being what Travis knows and what he has done to mustangs do you think he would volunteer to dyno tune the car and put his reputation on the line if the #8 cylinder was hurt? I seriously doubt it...
