Pulled the side cam covers off to quickly check the timing. It looks the same from
earlier this month, so I think that's fine.
Next, pulled each injector back out again to re-inspect the seals, etc. Driver side ones looked fine. Pulled out the passenger ones and found that on BOTH, the '
injector seal' o-ring was cracked and/or lodged down the intake!
Cylinder 3
Cylinder 1
Since this damn o-ring isn't standard, I decided to put the injectors back in with out it and see how things go. Will try to find it tomorrow, but I'm expecting a week+ order. *sigh*.
First fire up, it takes a LOT of cranking for it to slowly catch. Then when it does, its running badly as before. With RevScan I see the 'Spark Advance' parameter is 35 deg, which is way off normal. Let the engine run a bit, notice some smoke coming from the engine bay and shut it down. Inspect the area and determine its some fuel that spilled onto things when I removed the injectors. Reset the ECU (via revscan) so all the badly learned fuel trims are cleared out, along with the timing, etc.
Fire it up a 2nd time and it starts almost normally. Notice the vacuum is ~19 inHg -- sweet, I think things might actually be ok...Slowly it starts to get worse and the vacuum creaps back to the 15 inHg range. The Spark Advance stays around 22 deg this time though. While I was paying attention to the dash and revscan, I neglected to notice the giant plume of white smoke pouring from the rear of the car. HOLY CRAP. The whole garage smelled of unburnt gas! Not sure if its just residue from the earlier flooding... but things didn't get better after a good 1-2 min of idling. Turned the engine off and am giving up for now. Hopefully the injector spacers are the fix, but thats a week or more out. I'm kind of thinking they won't be due to the vacuum leak of some sort -- or maybe thats the ECU compensating for the 2 injectors with too much fuel?
