Hi Philip A,


No, not the AC - unusually, I was running all day without the HVAC system.

Hi, do you have EGR?
if you dont have access to diagnostics to read some live data
1. unplug the MAF and see if it cures it or not, a bad MAF would cause that on a auto
2. clean the AAP sensor(the one in the airbox) with electronic contact cleaner spray
3. inspect the upper plug too which connects to the injector loom, if it's oil there the injector loom is already gone you dont have to expect the oil to get to the ECM
do you have EGR?

the best would be to plug in a tester though otherwise it's a guessing game

Hi Sierafery,


EGR is disconnected.


I do have a Nanocom and took some fuelling input recordings yesterday but, I'm not sure what to look for in the data or, do I need to record some other data?


I'll have a look at the other items on your list this morning.


Thanks for the suggestions.

record live data(instrument mode) on a longer drive then convert it in excell file and post them here....didnt you get any fault codes logged?

if you can't do that watch ambient pressure on instrument mode and see how it behaves when the symptom occures... air flow as well

How do I convert the Nanocom data into Excel format - can't seem to find any info on how to do it with a Gen1 Nanocom - user manual was not revealing either.


This morning I checked the ECU plug at the rocker cover - no oil to be seen.


The symptoms are intermittent - this morning she ran fine but started to play up in the afternoon.

it saves as a csv onto the card

Save the file to your computer

Open it with excel (right click open with)

select the column - then Data>Text to columns

It will then create columns from whatever the csv file has used to separate the data.

Thanks Stallie but in my case it does not save it as a *.csv file - it's an *.ful file and when opened in Excel shows a whole bunch of gobbledygook!
