This past summer, I noticed that AFR was showing leaner mixture under load than it had and there was some loss of power when engine is hot. Also an occasional hesitation when cruising at mid range.
Nothing serious, but decided it might be time to do a lot of things. Starting with:
- Upgrade engine harness (under way)
- check injectors for equal flow (under way)
- replace plugs with BP6ES and check wires (under way)
Will post some pics and progress from time to time.
Plugs
Installed new NGK BPR6ES plugs in Spring 2008.
Timing set to about 27BTDC at 3000rpm.
Mixture on rich side at idle and approx to specs under load (using AFR gauge)
Today, took some pictures of plugs. Look OK, but some variation and maybe confirm running lean? Plugs too cold? Here are pics ( By the way, I had injectors 3 and 4 connections reversed. But on Djet, not sure how much that matters!)
Need to check plug gaps, but need to find or buy new feeler gauge set!
