He's right, but let's not lower it until we can get the O2 up, and keep the maf down around 6

If you lower the fuel pressure wouldn't that create a leaner mixture and therefore the o2's would rise?
My 3 in maf always idled at 7. I didn't worry about it.

Well, with lots of help and lots of part swapping got it sorted out! turns out the translator was bad, and the powerlogger was bad also. 2 faulty electronic items make a guy want to lose it!!  its a bummer about the PL as they are awesome to have! Also after bleeding the brakes 3 times figured out the master cylinder was bad. Replacing that tonight and then she will make a maiden voyage around the driveway. Cant really drive it yet as in search of an elusive TV transmission cable. Progress!!! :)

Bob will fix the PL for you, I think.  Tell him what you found and ask him if he will look at it for you👍

Trying to sort all my cooling fan problem. If I ground the temp sensor wire that is directly under the throttle body with the key on I thought that should make the fans come on but it does not?

The fans do work because I've been turn them on manually with a switch direct wired

I'm not sure how those fans are wired.  Here is a write up I did on the factory wiring which might help sort the factory side out.  It is quite possible that a relay or relay is bad.  This might help you figure that out ??

Update time, got the fans figured out and the snow melted off the road so we took it out for the maiden voyage. It runs okay it holds first gear forever so I think I have to adjust that TV cable better, the alternator must not work because it only puts out 10 and 11 volts when it's running so I'm sure it's just getting that off the battery. Still has a terrible stumble when you Goose the throttle I think maybe I need new injectors and it certainly does not like boost. But other than that put about 5 miles on and I got us back home in one piece so I'll take that as a small victory and keep trying to work the bugs out

Check the voltage at the back of the alternator.

Does the volt light come on when you turn the key on?

Move the cable one click.

Check the fuel press to see if it is behaving properly.

Do I move it one click towards the firewall, as in if 4 ribs show, make 5 show?

Also going to pull injectors and try the you tube bench cleaning method with a spray can, some tubing, and clicking power to them till I get a nice spray

in my opinion, it is worth it even if it seems about 50 bucks too high
