New 3.4 liter build idling

[WYDBODY1986]

Finally finished! Well almost. Here is my engine idling after a short run of twenty miles. Sound like valves may need readjusting let me know what you think please. Can’t drive it much more because my AEM AFR guage is showing it running quite lean in the 15’s at idle and 15-16’s at cruise. Under load I don’t think I saw it drop below 13’s so I’ve got some investigating to do I guess. I did not replace anything in the fuel system except for the filter. Time to study fuel system diagnosis in the Bentley.
Here is the link, hope it works

Where is your AEM wide band installed?

I disconnected the stock O2 sensor in the cat bypass pipe in the stock exhaust and hooked it up there. It’s a 3.4 with 993SS cams, an enlarged throttle body and a dansk sport muffler. I checked the fuel pressure, the WOT switch, the Idle switch, all the vacuum lines and listened to all the injectors with a stethoscope to make sure they were all clicking. It idles dead smooth at 880 or so and seems to have some power as far as I can tell. The chip is one of Steve Wong chips for a 3.2 with SSI’s which I no longer have. I’m thinking of setting the fuel quality switch in the DME to the 2 or 3 setting to richen the mixture up that way just so it’s safe to drive for now

Those AFR's are not concerning at cruise.

But yes, at load, I'd want lower than 13 for safety and possibly a tad more HP.
