Ok, update. I took a few logs earlier. Each log subsequently adding a bit more ASE and WUE. Obviously you can only adjust this so many times in a short period, because the coolant temp heats up and thus is no longer a "cold start".
The final log was with an ASE and WUE of ~55% and ~155% respectively at ambient temps (60F) and ~35% and ~135% at about 120F.
Here's a better description of the symptoms. If my foot stays away from the gas pedal, on a completely cold start (60F), the engine will fire and immediately die. Almost like a weedwhacker that fires when you've got the choke on and then dies...
I can keep the car running on the first try with the throttle, which is a royal pain in the ***....especially with my tremendous belt squeak that sings to the beat of the throttle position.
I'm attaching 3 logs (try 1,2, and 4...forgot to record 3). Each log has a bit more ASE and WUE. The final log shows my starting the car, me using the throttle to get it idling, and then letting it idle for a while. You can see it idles like crap for ~45 seconds and then smooths out. WUE is on the entire time the log is running. You can see coolant temps don't rise very much because I was just sitting there idling.
Now, before you go bananas, yes I see that AFR is pegged at 7.4. I'm working with the prior owner to figure out what kind of O2 is on the car, if any. (This may be an open loop setup
). My understanding of MS is that it starts the car in open loop anyway, which does not receive an input from the O2 sensor because the O2 sensor is theoretically not heated up or sending a signal. Am I wrong? This leads me to believe that this particular problem lies elsewhere (and I have a WB O2 in a box ready to be put on the car, no worries...I'm not crazy).
Do I need to dump more fuel in? Running RC550s.
Any help is greatly appreciated. My learning curve remains vertical.
