- Has this car ever run with the engine change?
- Who did the changeover? Someone who knows these cars and the AJV8 series changeover in 99?
- When the AJ27 was installed, were the electronics moved as well?
Basically, you have codes all over the place and I assume some of the answers to my Qs are that it has not ever run with the new engine and you've changed over from an AJ26 to an AJ27, probably trying to run the 27 on the 26 ECM and TCM?
