Bank 1 is lean! Help please OK I had a broken trickflow upgraded valve spring on the exhaust side (https://ls1tech.com/forums/generatio...m-misfire.html ) and I was lucky enough to have TEA send me a new one. I installed it again started it with new Tr6's and 2 new o2's. But the car is still running pretty lean on bank 1 still the same way it was running when the spring broke. The car is like missing during acceleration but once it hits 4k it comes alive! I have aeroforce guages and when I switch to the short trims b1 and b2, b2 is always in the -. whatever but B1 is always + anywhere from 2-14!. What can be wrong? Is my tune off? can the PCM loose its program? What can the problem be?
Thanks

Try to check the + wiring to the injectors. The - is regulated by the ECU.
What you can do is to measure the flow from each injector in a cup and measure cc in the cup.

just a thought swap injectors from 2,4,6,8 to 1,3,5,7 look in the end of the injectors especially #1,7 as they are at the end of the rail. I had a similar problem ended up being #7 injector was full of ****. Went thru cleaned all my fuel lines fuel rail and injectors out and car was back to normal...being turbod i thought i lost #7 cyl so for me to find dirty injector made my day 100x better!
if the problem moves to bank 2 u know u got a bad injector
BTW injectors still click like they are firing if they are packed full of **** so listening just isnt enough.

Lol no I didn't mean it towards you!
I meant it towards the car that doesn't wanna tell me exactly what her damn problem is. Sorry you took it that way !
Kelly Smith: while I was looking for the broken valve spring issue I had all injectors cleaned and flowed and I put the 2 inj. that flowed just a Lil more on cyl #7 n #8.
