Plugs aren't platinum. It'* regular cooper I guess.
Yes,original problem has been corrected and this topic can be closed.
Last year in July I started topic about misfire and it'* still unresolved.
Anyway, I'm not going to spend any $$$ to buy compression gauge just for one check.
I already loaded with all these scanners,fuel pressure gauge ,charger ,diff tools like I'm going to open my autoshop
Thanks everybody for help and best regards.
