A brief update - After 2 months and three pages of replaced parts, it isn't fixed. GM even sent an engineer down to help with the process without success. I had taken the lead tech on a drive to show him what it was doing and he took the engineer out.
I now have the car back and the next step...
I just got my car back after 2 months and no, it isn't fixed. But I did get an extensive writeup on what they checked and replaced (a lot!). It is apparent that the GM engineer they sent to try and figure out what was wrong was familiar with your situation, I was a little confused by their...
I assume they saw material in the oil to diagnose the rod bearings. Just seems like a lot of people have had major engine issues and that is discouraging.
Closing in on 45 days and no joy. They have targeted the 6th cylinder and replaced ignition pack, plug, wire and now injector. They keep having to send files to GM and wait for GM to tell them what they can do next. I have talked with the service manager and the lead tech, all are frustrated but...
I am scheduled for March 20-21 and have a semi-long flight home to Indianapolis. Given we don't get done until 4:00pm, are you trying to fly out that night or staying somewhere and flying out the next day?
Update - no Update :(
After almost a month, no progress on my car. Service keeps saying that they are talking with GM and sending them files. They say they see a misfire in cylinder 6 but nothing they have tried so far has fixed it.
Everyone I have dealt with has been great but the lack of...
There were only a limited number of the "Blackwing" engines built and the few that were left over after production of the CT6 Blackwing ended, I believe, went into a few marine applications.
The engine was cool but very wide and difficult to fit into anything plus was very expensive to build. If...
Update - They saw a misfire in cylinder 6 and replaced the plug, ignition pack and wire. Didn't fix it. They have now had it for over a week and are still talking to GM. Now think it might be an injector and waiting for GM to tell them the next step. I don't think they have worked on many LT4...
Update - It is at the dealer and they cannot locate the cause. They checked the plugs, asked the gas question and are now talking to GM.
It is not creating any codes beyond the one emissions code that they said was too vague to be of any help.
The service people at Lockhart are being great and...
