Hi.
Well i seem to have landed with a problem.
As many have read I fitted Denso IXU22 Iridium plugs fairly recently and up to now have been very pleased with the results.
Saturday we went on a 128 mile run, 90% motorway with 4 up. No problem at all with the exception after around 60 miles at lower speeds I noticed some suttering and jerking.
Yesterday I was out for 10 minutes and this was pretty bad (fine above 2500rpm), no management light or codes stored, that was using Afa OBD on my android phone. Even read my ECU data (programmed Jan 2014 software 0000 update 00)
I'm going to refit the old NGK's to eliminate the new plugs, i've also tested the leads and they all read between 190-250 ohms.
Any other ideas?
