Thanks Marty, I've been playing with this since last October. I don't keep plates on it so I've only driven it a few weekends since then. I replaced plugs, cap and rotor about 18k miles ago.I always run Chevron premium fuel, make sure it's hot at the test center. I think adjusting it with a gas analyzer just to lower the HC's is the only way it'll pass.
Last weekend I drove it and had the ABS and CE light come on about an hour after a trip through the touchless carwash. It wouldn't restart (thankfully it happened in my driveway)so I checked the battery voltage and it was only 11.5 V. I charged up the battery and dried out the OVP relay. The next day all was well. I tested the engine and found the following:
KOEO Duty cycle 68% then drops to 64%
Idle contact 9%
Full load contact 19%
Engine running cold 48%
Engine running warm 51-56%
O2 sensor cold and warm 0.1-0.8 V
These are all normal except the KOEO. I drove it about 150 miles on Sunday and as I was going to top up the tank before putting it away the ABS , CE lights came on again so I drove it home and parked it. The battery was at 11.5V again. I recharged it , resoldered the OVP (again)after I discovered moisture inside it.I also tested the OVP and it checked out fine. The low voltage might not be related to the OVP. This is fun
