Hi All,
Have a series 1 r33 GTST, recently had a second hand engine fitted all running well. Problem i have is witht the previous engine i started to experience an intermittent problem i.e on occasions when you started the car it ran like it wasnt firing on a cylinder, sometimes a simple restart would rectify and all would run smooth sometimes it just wouldnt run smooth for the whole day. Anyway that engine is gone and had new engine in for almost 8 months now never had a problem, in the last week or so it appears to be doing the same thing again start up she sounds like it has dropped a cylinder but this time i just restart and problem goes away, am worried problem will get progressively worse till its same as before.
Anyone have an idea as to what is causing this
