no vacuum on boost gauge

Not a problem, I'm not offended it's just fun.

Your assessment of what the 02's should be doing is correct but the readings you are getting seem off...And I'm not sure how effective the cleaning of the injectors was...Sure they can be cleaned but whether or not that helps anything, I don't know....With these injectors and the pressure they operate at, typically it's a mechanical or electrical problem with the injector.

See, we can have a civil conversation. Yes, the readings im getting from o2s seem suspect but like i said, im still learning how to interpret that data so not sure how that plays a role in my problem. And as for the injectors, your right, who knows how well that cleaning processes worked (syringe and hose connected to top pressurizing cleaner through while pulsing injector off battery) but when i removed them there was build up on all the tips so after cleaning the tips i thought thouroughly cleaning them could help. But sure didnt. I think ur right about getting the update. Ive heard some things about that too

I'm surprised they were able to run at all, the ECM injector driver provides 65 volts to open them. Some companies say they can test spray patterns at low pressure but I don't believe that at all because I've seen in cylinder pics in various research papers that show a dramatic change in atomization as pressure falls.

Please be careful when screwing around with these injectors, they can operate at 3700 PSI and if you inject fuel into your skin at that pressure your chance of death is extremely high!

I attached a doc that might help your troubleshooting adventures.

Do you have videos of the spray pattern before & after?  Pics of the injector itself?

I do not. I should have though. Do you think it may be an injector problem?

Could be.  Not sure old school techniques will work on GDI injectors, they might. And new seals are required each time you R&R GDI injectors.  Anyway, checking results is what counts.  Maybe the pattern is fine, but the solenoid is not responsive enough.

65 volts?? Damn thats alot. They were opening with just 12 volts off my drill battery. I hope that doesnt mean theres something wrong with them. And thank u for the document. I will be looking that over.

Before removing them i got all new seals for them :-)
