Hello all, for about 3 weeks I have had lumpy running issues, and lack of power with my P38 Vogue (4.6 THOR ), have had it on the Nanocom, Maf,Lambdas, all seemed OK, did a Compression Test, and got a high reading on No8, after doing some searching I thought broken Rocker Shaft, so ordered a new one, the next morning it was running OK again, I was baffled now! A week later it was running rough again, a rocker shaft cant break and then repair itself can it? so I'm now thinking CATS, as I've had the Bad-egg smell during this time, had it on the Nanocom again and got fault code PO300 Missfire multiple cyls signal Too High Drive cycle C I think it was. Went for MOT, Failed on emissions which I expected but only on CO on 1st and 2nd Fast idle 1.11and1.23 respectively, I was now preparing to spend nearly 600 quid on new Cats and Lambdas (Rimmers Sports Cats) to avoid dropping the crossmember, Today I had a thought maybe some new plugs might help, so I got a set of NGK'S, I opened the bonnet and saw No6 lead hanging in mid air! replaced it and all back to normal, fitted the NGK'S, went for a run, SWEET AS A NUT AND ALL THE POWER BACK WOO!HOO! fingers crossed emissions should be OK now, apologies for the long post, thanks for listening ANDY
