Hi guys

Hope somebody can help. My car throws up these faults under acceleration after about 4000rpm. I can reset the codes and the engine light goes out and drives fine otherwise as long as i don't go above 4000rpm.
Spark plugs, coils, fuel filter, air filter are all recent.
Any ideas?

All of those point towards a damaged CAT

Hi Malcolm,

I was thinking that one of the rear cats was rattling and loose so i removed it on one side

Hard to say as often it is the upper CATS that fail and block, lower ones seldom block, but I could be wrong.
