MGTF 160 Misfire issues....
Discussion
My OH has a 2004 MGTF 160. ill give you some background so as to make it easy as poss,
About 6months to a year ago she was complaining of juddering, this turned out to be a misfire, took it to our local Ex MG mechanic who changed both coil packs and adjusted the timing. Its been fine since.
Now in the last month or so the misfire has returned. The conditions are below 2.5K revs under acceleration. once its going it tends to be better.
My first port of call was going to be the leads. I read on the internet also someone had the same problem on an earlier car and it was a dizzy cap and arm they replaced, but then that the later cars dont have that?? is that true?
I havent really worked on MG's very much, is it all under that panel behind the roof?? i was told just take up the carpet and there are a few screws to undo.
Im handy with spanners but dont want to get to involved tbh, any trustworthy garages in the newbury area??
Thanks in advance, Graham

It'd be something of a minor miracle if an engine with twin coil packs also had a distributer doncha think?Pumaracing said:

The earlier K-Series cars had a distributor, later engines had a couple of coil packs to supply the sparks. TF160 is a later car. New plugs of the correct spec may help # they do not last forever.
My son and I have worked on a number of our own cars with the K-series including those with the trick Valve gear like yours ... the VVC.
Apart from limited access restrictions with the mid engine rear wheel drive configuration of the MGF/TF, the engine is one of the easiest 16 valve jobbies to maintain and work on.
