Misfire codes after head gasket repair
Hi all, took the xjr out for its test run today after replacing both head gaskets, tensioners, timing chain guides and various other water hoses etc. After start up, which in itself was a nervous moment!, it seemed to idle quite lumpy. Plugged in scanner and no faults indicated. Took it out for a drive and after 5 minutes or so it went into restricted performance mode. Plugged scanner back in and it threw 2 codes at me, one for a misfire and the other misfire/emissions too high. There is nothing more specific um afraid.
So am I missing something simple, or is there something more sinister lurking? Could the timing be out & the car run lumpy? I used the correct timing tools etc and all appeared to be fine when set and all turned over by hand after & before I fired it up.
Any help or pointers greatly appreciated.
Cheers all. Si.

There is a definite whooshing sound coming from around the supercharger area. I have resealed the rubber gaskets between the top cover of the supercharger and the charge coolers and the charge cooler manifold gaskets have all been replaced also. The electrical connections appear to be ok, but i will take them off again and put some electrical cleaner on it all and clean them up as they have been off the car since October last year.
