before

1 - 235, good
2 - 229, good
3 - 218, dripping
4 - 234, good
5 - 230, good
6 - 228, dripping

after

1 - 241, excellent
2 - 240, excellent
3 - 239, excellent
4 - 241, excellent
5 - 240, excellent
6 - 240, excellent

so, gas in oil due to two dripping injectors. no response to turning off injectors at two cylinders due to two dripping injectors. p1128 due to lean condition at max rich due to two injectors producing low cc/min.

best money spent yet; excellent work rce!!!

ps - sniff your oil!!! gas in oil apparently can facilitate ims breakdown (gas acts as a solvent to scour grease and oil from the bearing i guess). a dripping injector, coupled with not running your engine long/hard enough to burn the gas out of the oil (hence the rumoured trend of ims failure happening more to cars driven lightly or with a long interval between oil changes) could create these conditions.
Nice set you have there! You will be amazed at how smooth your engine runs.
