injector was correct injector. I bought another one to do some testing. swapped in, now two, brand new injectors. I'm going to do all the injectors in the next week or so. injectors I pulled the screens look pretty clogged. I checked for vacuum leaks. i'm reading 19 inches vacuum. I think thats fairly normal. when I hit gas it goes down to 0 pretty much but jumps right back up. I checked long term fuel trim and bank1 is still sitting at +10. I reset the preprogrammed values in the PCM with the forscan tool. Started up normally. watched long term fuel trim slowly build back up to +10 on bank 1. bank 2 just stayed about the same. This is a damn mystery. I guess I can get a fuel pressure guage and check fuel pressure and see if its acting funny. I checked the fuel rail diaphram. pulled vacuum hose to it and smelled it. fuel pressure guage will tell me if its actually doing its job. hoping for any input from folks.
