After reading some more on the subject, I find that the AAVs are adjustable. Live and learn.
My Testarossa is an 87 with KE jetronic, and is F113 A040, 00586. It has auxiliary air valves (AAVs), no warm up regulators, and black boxes on...
Sorry but I know nothing about bouncing plates. Did you get screws to replace the ones missing? BTW, did I see somewhere the mention of Alfas? I...
Plip I have the exact same problem with my 87 TR. I have gone thru everything with all of the advice from the experts here. No success. I do...
I have an update on my car. I checked the temperature of the exhaust, 1 -3, 4-6, 7-9, and 10-12. I-3 was very cold, 4-6 was warmer, and the rest...
Sorry I was not clear. 1. Yes but it was open or closed look and the value stayed the same, adjusting the screw or not (very little erratic...
I changed out the O2 sensor for the passenger side. The voltage moved from 0.744 to 0.54. I tried to adjust via the mixture screw with no...
I did adjust the drivers side mixture screw CCW until the engine ran rough. I then adjusted it back CW about 1/16 and it ran smoothly. All of...
So, the passenger side is approximately correct but would be better if the mixture screw could be adjusted a bit rich so it would run better at...
So, is it suppose to swing from 0.1 to 0.8 volts normally?
More data. I am not as yet able to get the passenger side mixture cover screw out. However, just to see what happens I started the engine with...
Yes, I have two voltmeters and both are connected as you described. We can assume that the passenger side is running lean and I can not adjust it....
Sorry but i had my sides confused but now are straight. I can adjust the mixture screw of the drivers side and I get no response as it stays at...
I now have more data and it is not encouraging. My drivers side is running 0.744 on the O2 sensor with the engine hot and with 15 inches Hg on...
The screw that covers the hole is exactly as you described. Dirt and whatever made it difficult to see. Now, onward. I removed the screw and put...
I am not able to remove the plug. It is 6mm hex and will not come out. As it is aluminum it is soft and when I turn the hex key and can tell...
Steve, How do I make sure the protection relay is working correctly before I adjust the mixture idle screw? All I did was replace it when I found...
Steve, The WSM that I have shows a WUR in the pictures of the engine (D3, figure 2) so since I started on this quest I have not trusted the...
Steve, I am adjusting the wrong screw. I thought the mixture screw was the large brass screw that is spring loaded. There is no hole in them....
Oops, what air hole? Back to the car to look for them.
