I was hoping someone could maybe take a look at the data log file I've attached and let me know if there is anything "wrong" with it.
My car (K20 supercharged Ariel Atom) has started "misfiring" at approx 3500rpm in pretty much every gear, most noticeably in 3rd and 4th. It doesn't do it every time, probably seven out of every ten times that I rev through 3500rpm.
I pulled the spark plugs and this is what they look like:
It feels almost like the fuel momentarily stops flowing, the engine jerks and sometimes there is a loud backfire. I've changed the fuel filter which made no difference, and I also changed the battery as it wasn't holding a very good charge (the Atom uses a very small battery). The injectors are ID1050X and only recently fitted.
If it was an injector issue, I would have thought that the "misfire" would be random, but it's always at approx 3500rpm.
The datalog was made whilst I drove in a manner trying to repeatedly get the car to exhibit the issue, so I'm hoping something has been captured that will mean something to someone who fully understands these logs.
I would really appreciate any help.
Thank you
