Sounds like this Saturday Matt and myself are gonna do some electrical upgrades on his K5!
We'll be doing the headlight relays, tie the lights together so the low beams remain on while the high beams are on, installing a heated oxygen sensor, and repairing a broken knock sensor wire.
Should hopefully take care of his engine problems, while increasing power and efficiency. I can't think of any way to make a fuel injected engine run worse than straight off the tables in the prom!
Been a little while since I've been able to play with a truck, so it outta be fun so long as it isn't too cold out, lol
