Mmmmm ....phase position not doing what I thought it would be doing , actual timing is advancing with speed as I thought it would ......we could do with another member looking at there settings to compare readings on that phase position , just in case we are going up the wrong pathway .
The idle reading fuel trims are spot on , you would think if injectors where over or under fueling you would see it at the idle fuel corrections , on the partial throttles there's some correction but not so bad .
If you watch short term fuel trims on the road is there any areas of throttle where they go widely out of range .
What would be interesting.... the camshaft position sensor on the drivers side bank ...the easier one to get at , looks like it's held in by two 10 mm head size bolts , if they are slackened is there any movement clockwise or anti clock ...like turning an old type distributor , I just want to see if moving it what it does to the phase position kW readings and in turn what that does to the partial throttle short term fuel correction values .
For how heavy it is on fuel you would expect the trim values to be showing a rich condition or is it a case of its leaning out and the engine becomes in efficient and that's using the fuel , do the spark plugs show any signs that's it's rich ....bit dark in colour ?
Interesting one this
