Yes I checked the readiness and cleared the codes. I get the p0241 code for the cat as well. Only after sitting overnight with a cold start!. Clear after hot and go for a drive and the code doesn't show. Might be time for a new highflow cat
How accurate is your speedo at 100 2kph ? thats well within spec. When you think about it must vary a little with tyre wear.
Amazing how hot the intake can get sitting in traffic ! Seen it go 25 deg over ambient and then drop to almost ambient again going down the highway .
Still working out the fuel trim thing as well.
