Drove 1000 miles or so to Las Vegas and back.
On the way there I could feel a miss fire that was intermittent.
P0300
Pulled over checked spark plug wires and distributor cap for any loose connections.
Didn't find anything kept driving, bad gas maybe?
Then it got worse and more consistent...
Crud.. started calling auto parts stores on the way. For plug wires and ignition parts.
P0306
Ok so now the misfire is one cylinder .. head gasket, spark plug.
P0171-Lean bank 1
Pull over 2 min from orielly at a Lenmoore high-school parking lot where they have plug wires. Look again in the engine bay for issues.
There you are you glorious Mother trucker!
This is to the jumper for injector #6
For the upgraded fuel injectors.
my kid had to poop.
Recrimped the wire while getting rained on.
Ran strong to Vegas and back home.
Having the ultragauge helped a ton to give me insight into the issue.
