Hi,
I have added as an attachment, the full Pscan live data file if anybody wants to have a look using a spreadsheet, tab delimited seems to work.
I noticed two things :
"Cylinder 1 misfire count" - sometimes says 1 or 2 but also 256 or 512.
Downstream O2 sensor reads higher voltages than the Upstream sensor reads, that can't be right even if there was no Cat!
Today I looked Ignition because of misfire values.
No tracing visable in the dark.
Pulled boots off coils - little bit of white corrosion - cleaned off with alcohol,
Swapped positions over of coil 1 and 2. Misfire in live data stayed on cylinder 1.
Checked spark plugs. When I first put them in I could not find my gapping tool so trusted the factory preset - all at 1mm except cylinder 1 which was 0.8mm - regapped to 1mm, Don't think it made any difference but I ran last live data before this.
Noticed wires to coil packs have been played with.
Performed a compression test,
Cylinder 4 - 14 bar (200psi)
Cylinder 3 - 12 bar (175psi)
Cylinder 2 - 15 bar (220psi)
Cylinder 1 - 15 bar (220psi)
Took a phone video of exhaust sound but it appears too big to attach.
An air pipe is hanging off the air box, don''t think it makes a difference though.
Swore at a group of Ravens in the tree overhead.
Forgot to include, I put a sheet of paper up near exhaust pipe for a few mins too see if there was any soot. Just a bit of rust from pipe edge.
