So ive been fighting with leaking in jectors for a while now, pulling the plenum 4 times now. I had bought seals from z1 and they leaked no matter whatso bought directly from dealer so to know they would be factory. I installed them and tested with guage outside of car and it held good pressure for several days. Ok so yesterday i get everything put back and start it up and it runs perfectly no smoking and great idle. I shut it off to clean up and then 15 min later i start it back up and it would barely start and I did a power balance and it was only running on 4 cyl. I start it again and this time so much fuel leaked out it filled several cyl causing hydrolock. RIght now i took the plugs out to let the fuel evap. Now i did everything correct I know this time around and in testing before install they didn t leak at all. Could they be stuck open? Another thing is they seem to be very loud, more than they should be at idle. Help would be appreciated, thank you.
