After Saturday's maintenance project we drove the 9-5 20 miles or so on Sunday with no issues. I drove it 35 miles to work today with no issues. I drove it across campus and back for two different meetings today, total of 6 miles, with no issues.
I leave work tonight, go maybe 3 miles and the engine dies. I coast into a driveway, pop the hood, all electrical connections look good, and restart the car. Ran maybe a little rough for two seconds or so then smoothed out.
Drove another 6-8 miles which put me on the expressway and the car dies again. Attempt to restart and it would not stay running. Hmmm, acts just like my Viggen did when the TB Inlet Tube popped off. Sure enough the tube came off the TB so I get the factory screwdriver like tool out from below the spare tire and tighten it. Start the car, travel maybe 200 feet and it happens again.
I pull to the side of the road again, replace the tube making sure it is all the way down over the TB collar, and really tighten the slightly mangled 7mm slotted hex. I restarted the car and now have a CEL that I did not have the first two times. I drove the remaining 30 miles home on back roads at 55 mph with no further incident.
Tightened the slotted hex with a socket & ratchet when I got home, nearly forget about the CEL, and just checked it now a couple hours later. P1300
I thought the P13xx series of codes were all DIC/IDM related. Is this related to the tube popping off the Throttle body?
Regardless, I have decided that thin O-ring on the TB inlet collar is a disposable part and should be replaced every time someone removes the tube to do maintenance or for engine bay access as I did Saturday. I thought I had another spare in my parts cabinet but I obviously already used it. I better order 6 of them to keep spares in both the 9-5 and the Viggen.
