2000 XK8
Car starts and drives gently OK, but enthusiastic driving or a steady drag when hot can result in a"rumbling" and sometimes RP. Pending codes are misfires on all cylinders and 1316- which is what flagged RP. Don't think it is coils as when it goes-it goes, it is after a good bit of throttle, it refuses a repeat performance.
Thinking it is fuel starvation, the filter has done no more than 4K miles and I am starting to think it is the fuel pump either losing performance or the mesh filter is blocked.
Have a full tank so while that is consumed, will clean the MAF, check for leaks, clean the connectors etc. Also, will go for a drive with he OBD2 connected to see what the fuel trims are up to.
