Today was going to be a good day. I had the newly-repaired fuel rail in hand along with my new in-lb torque wrench. After torquing down the fuel manifold and intake manifold and plumbing the intake, I pressurized the fuel system about five times and took a look under the hood. Would you believe the other end of the repaired fitting was spitting at me!
Apparently the shop didn't tighten things up enough. I wish they had brazed the threads of all the fittings! At least the fitting wasn't pissing fuel like before!
A few turns of a wrench later, the fuel rail seems up to the task of a short drive to AutoZone for some engine oil. I let the car find idle, then show it 1500 RPM for a minute, then I hit the road. On the way out, the car acted like I was power-shifting. The throttle would spike 1000 RPM when I put the clutch in and selected a gear. On the way home, things got much worse...
Twice when I approached a stoplight, depressed the clutch, and put the car in neutral, the RPMs soared to 5K!
HOLY THROTTLE HANG, BATMAN! I feared it would bounce off the rev limiter! It didn't, but it took almost ten seconds for the RPM to come back down so I could shift into gear without spinning the tires. My plan was to change the oil tonight, but I'm afraid the car will try to kill me once I crawl under it. I guess I won't be driving to work next week.
The only DTCs I have thus far are the following:
P0172 - System Too Rich (Bank1)
P0175 - System Too Rich (Bank2)
P1000 - Monitor Testing Not Complete
P1405 - DPF EGR Sensor Upstream Hose Off or Plugged
