my first log using EEhack...

Just done my first data log with EEhack… see attached photo. Seems some problem areas, just learning, so any help, advice, direction is greatly appreciated. I have two logs saved. the red line seem to normal off idle, just sitting in the drive. Did not take car out to record during a drive.

thanks

you have some issuees with fueling or spark, can You attach log file with atleast 2 in of idling in CL ?

best regards

See attached data log via excel "WASyL"... thanks for your imput.

Knock counter looks odd. ECM is pulling lots of fuel, eighter because you have bad oxygens sensors, to high fuel pressuer, leaking injectors, faulty knock sensor or ECM.
I would start with checking fuel pressure that should at around 39,5 PSI at idle with disconnected vaccum line. Then check that knock reading, that might be e reason to.

Thanks brother....Will advise. Also, asssume those o2 have 194000 they might be alittle tired

I see the maf reads a liitle too high for hot idle. It might be fouled leading the engine to run richer than needed. That`s why the pcm is pulling fuel.
