I need to understand
If the catalystic is plug system will be rich or lean?
Injector ramps look ok it have pintal micanical movement is that mean the flow rate is ok or it meen the injector jest open how to know bad injector from current ramp ?
If the trims and O2's go rich or lean... depends. :silly: If it's a single bank MAP or MAF system, you'll likely see rich (negative) trims. If it's a MAF system with two banks, you'll see negative trims on the bank with the plugged cat.
The injector pintle hump only tells you mechanical movement took place, nothing about flow or spray pattern quality. You'll only pick up a bad injector with a voltage or current ramp if there's something wrong with the pintle movement of the injector.
