the p1700/1781 come up more than ther misfire code but  they tend to come up wiht lots of other codes

What gunge from plug wells?

Misfire is one issue, tother is Cam sensor... Clue here is the 1700 transmission code. Generally cured with genuine sensor from genuine Vx dealer that you genuinely have to walk into.

Misfire will be either scuttle or Camcover gasket, or both, depending on the gunge

was wondering if cam censor could be anuy thin to do with it  but funny had them codes as well when mass air flow was playing up   
 but its the lumpy runing  i stated it from cold erlier was as lumpy as any thing  turned of and re started as smooth as ever  againe
as saidiv clean the plugs and hols  from gunge andoil build up  and still doing it i think so would coil pack cuse lumpy tickover but seem to rev and drive ok  or could cam censor play in to it as was so long ago i did it  all i can rember was it would go in to limp home mode every time you statred

oh well found fault today none of the above was start of head gasget going took  sarted fine this morn took for a sharp run   then light cam on and stated missing  even will driving got back was mores steam coming out of exust that a traction engine  tured of  read fault code pulled number 4 plug wich was soacking wet and you could see watter in cylinder turned over with plug out and was like a gezzer so  now its wether to pull apart and soo whats  going on or scrap yard as im llooking at £200 to dowith a service and belt will im about it shame really just put 4 new tyres on and a back box but hadd 11 year fathfull use
