Still getting misfires with all new coils & plugs
Car is a 1999 TL with 277k km
Codes 0300-0306 & 1399
Issues started last year with one failed coil and a EGR port recall kit.
Since I've been replaced the plugs (NGK Iridium) and the remainder of the coils as they've dropped off on at a time.
I'm still getting the misfire codes, last time I reset the ECU it was 3 days of driving before I got one though.
I've tested the new coils with a multimeter, 2 from the dealership are 16000 ohms but the other 4 I ordered online and are 10000. Is that within spec?
If that's not the problem, what's my next step?

Hey Hurricanejosh, the '99 TL's had lot's of EGR passageway problems with clogging up. Try going back in and ensure that everything is clean.
Check with the DIY sticky for more details. Also may want to consider a quality fuel system cleaner. Inspect all the wiring and vacuum connections.
