Thanks for all the help. Lol definitely a interesting start although went out for Nye and ended up buying a is200 with a scrap engine For about the same the lsd should be worth but long story short I'll not be allowed out again for a long time 😂.
Just a quick update.
Pulled each coilpack while car was idling and all but one made the misfire worse. Leaving me to believe either plug or that coilpack.
Going today to get a full service kit with plugs and have a lexus bought with a siezed engine so will pinch a coilpack off it.
Hopefully should remedy the situation but once I have the service done I'll update .
Also main reason I'm suspecting the coilpack is this is the first week I've had the car and was told when buying it has been lying up for 3 months.
