I need help setting the timing, and working out the bugs (for a laugh remember the kid on the Little Rascals "bug hunting" with a hammer).
The 87 S-10 is now running code free on the computer. I took it for a short ride and it was amazingly gutless - struggled to get it up the driveway. I retarded the timing (turned the distributor) a few degrees (per a light from ~20 to ~15) and it seemed much better. I took it for another ride and was surprised that the 4 wheel drive is also working. It had great power too, except that it occasionally seemed to go into a sort of limp home mode. I messed it up again fiddling more with the timing, and can't seem to get it back like it was that 1 drive.
The last drive I got stuck in a little hump by the driveway and had to pull it out with the other truck. It only made it back to the parking space by putting it in 4-wheel-lo (lower gear). So I'm thinking I need to figure out:
- How to properly set the timing (ie: disable computer timing set it to the proper setting, re-enable the computer and verify). I noticed the test jumper seemed to set the timing to a closer to constant value - is this a good approach? There is also a single wire with a connector on one of the wires going into the ESC box on the firewall - is this supposed to get grounded?
