TBH i have read so much about "other spark plugs" causing the car to run poorly I think ill stick with the NGK PFR6E-10.
Hopefully after diagnosis ill know if they need repalcing... May turn out to be something else.
After my running problems with my car I Just popped into Renault Watford to price up a set of NGK's for my 172, i had seen them on Ebay for about £7.50 each but was warned off them by my old Man (Senior BMW Tech for a franchise) who said that they had seen alot of cars with running issues due to...
Just been out in the car again, Seems to have lost the missfire now but seems to be rough at Idle.
Its giving a very quiet pop noise every 3rd or 4th beat?
Exhaust hanger is about £27 from a dealer and a 2 min job to replace, You wont even need ramps to do it.
Shock about £50 and again an easy job to do if your semi Tech Minded.

Right my car developed a Missfire, one moment it was fine parked up and came back an hour later and it was missfiring.
So far i Have -

2 - Checked the HT leads
3 - Checked the Spark Plugs
4 - Checked Injectors
Very strange... Counting Cylinders from Right to Left...
Nah not yet! Still sounds cool though popping and banging LOL
Im sure its not coil related as i got a Nice Shock off each lead when i tested it LOL
Im now thinking Lambda / Plugs or HT leads.
My old man is back from his Holiday tonight so it will be a nice welcome home present for him to look...
