Durametric Question

[Gramuno]

Hi all,

I have recently invested in the Durametric software due to problems i've been having and would like to know exactly what some of the perameters actually measure.

My car is a ROW 986 Boxster S manual

Fault codes i have are:

P0154

P1128

P1130

P0300

P0301

P0302

P0303

I have just cleared these as i am more interested in getting real time date from the "actual values" tab of which i have been plotting results from the "misfire counter cylinder #"

The question i would like to know is where these numbers are coming from? would it be picking up the data from; supply to the coil packs?, supply to the plugs?, Any explosion sensors? or if something else what???

I'm asking as it makes a huge difference to where i go loking next whether it may be faulty coil packs (they have just been changed less than 1000miles ago at an indy) or the signal going to them from the DME, or just fouled plugs as it had been buring oil.

Any comments would be greatfully recieved

P0154 Oxygen Sensor Ahead of TWC, Bank 2 – Interruption of Signal

P1128 Oxygen Sensing Adaptation, Idle Range, Bank 1 – Above Limit

P1130 Oxygen Sensing Adaptation, Idle Range, Bank 2 – Above Limit

P0300 Misfire Detection (Sum Total)

P0301 Misfiring, Cylinder 1

P0302 Misfiring, Cylinder 2

P0303 Misfiring, Cylinder 3

These codes say your fuel mixture is too rich for the DME to control - to the point of misfires.

Since it is only on one side of the engine I think you should start looking for leaks and/or an air/oil separator problem.

Unless someone just changed the spark plugs (and cracked the coils) there is no reason for 3 plugs to all misfire at the same time other than a leak on that side of the engine.

In general , it would be very unlikely that all of anything would go wrong at once. Far more likely that something they all share in common is amiss.

My 2 cents,
