Anyone have resolved idle misfire cause? Mine come after track day. Spark plugs tightened and they looked ok. Part/full trotthle works ok. Block 32 values: -0.8 1.6 0.8 1.6. Thanks.

I'm running seimens 60# and they do missifire occasionally at idle, not too bad though. I know EPL has recently started using bosch injectors and claim that they have much better idle tunability and atomization.

Dont know if that helps any

Does greengiants known to fail?

I did let the engine idle for a while and then looked spark plugs, one plug looked a little moist.

I have:
-tested compression pressure two times=ok
-changed spark plugs
-changed coils
-changed flywheel sensor
-pressure tested=ok

Any injector can fail, do you have them oriented correctly? I believe that the harness connection on the green giants should be facing towards the fenders but don't take my word for it, I just know that their supposed to be oriented differntly than he stock injectors.
