AJP V8 Misfire
Discussion
Hello TVR community, I come in search of help once again.
Took the car out at the weekend, was running fine then whilst pottering through town I noticed it started running rough, 4 maybe 6 cylinders at best. It will idle but only just and has no power.
By spraying a little water on each exhaust I can see 1, 3, 4, 6 are running cool. I've recently change both coil packs and have confirmed the injectors are working correctly. The coil pack wiring seems solid. After pulling all the plugs the odd bank seems between good and rich, even bank is rich which can be seen clearly from the exhaust gases.
My diagnostic software seems to give spurious readings so I'm a little stuffed there right now. There has been no MIL.
My first thoughts are to replace the plugs and leads but I have a feeling this will not be the issue. I will also do a compression check as the plugs seemed a little too oily but part of me choses not to consider a head gasket, the financial bit mostly.
What would the next recommended steps be after this? Throttle pots and lambda came to mind but I would have expected to see a MIL.

Thanks for all the advice chaps. Unfortunately I'm still having no luck with new plugs and leads, with only a few hours a week to try and route cause I'm about to give a specialist a call. Very annoying as I enjoy spannering on cars but electrical gremlins are beyond my patience!
I will update this in future to add to the Cerbera problems wiki that this forum is so useful for.
