Rough running - Advice requested
Discussion
As the weather starts to improve the Chimaera starts to play up. Can I request some support from the wealth of experience here.
The situation is that the Engine appears to be running on only half it's cylinders.
I checked the spark, all appears to be ok, changed the plugs, changed the heat shield extender things on the plugs, absolutely no effect.
Changed the temp sensor for good measure, again no effect.
Checked the temperature of each port on the exhaust manifold, five measured around 340 degrees C, one was 90 degrees and two measured around 110 degrees.
Clearly there is a problem with these three not firing correctly or not at all.
Can anyone offer some assistance, could this be the injectors ?
I am no expert but would like to be able to resolve but clearly I need some assistance here. There is a smell of petrol on start up and it's noticeable that the fuel consumption has gone through the roof.
Would appreciate some advice.
Thanks.

Thanks for all the help, Dissy cap and rotor arm look to be ok but have ordered new just in case. Taking your point about faulty new parts.
Certainly the plug extenders do not seem to fit as well as the old ones, in fact a couple seem very loose compared with the old ones. I put that down to the old ones being on for some time and virtually welded on...
I will check that they all are working correctly as I was just assuming that new parts would be ok.
It's Easter weekend and the sun is out but I am still in the pits.......arh !!!
Thanks guys

Up date on the situation, replaced dizzy cap, rotor arm, new plugs. Leads all ok, changed coil but still not firing on two cylinders on left side(drivers side) anyone one got any ideas where we go from here?
Checked spark all looks ok.
I am at the end of my limited knowledge, I need your help.
I think I will need to get it to a TVR specialist and get a diagnostic check, where is a good place to take it in Berkshire / Surrey / Hampshire area.
I am desperate to get sorted this good weather will not hold for ever.
Any help would be appreciated.
