Started it up this morning, was quite hesistant, but I wouldnt say it took ages to turn over. On idle its around 700ish, but then drops to 500, then back up to 700. Cant quite hear a rattle as such, but when you look at the engine, it seems to be rocking when the idle gets lumpy. Its down on power and lumpy when you excellerate, almost jerky.
I cleaned out the throttle body last night, bit of carbon, however, when I looked at the cloth it was near black!! Did't seem to help the above though.
Its currently at the garage having both chain and balance chain replaced, and new oil, oil filter. Pick it up tomorrow, so will see if it had improved.
Changed the air filter and spark plugs the other week. I must say the rev problem was 100% worst before the plugs were changed.
I have a coolant temp sensor to fit this weekend as well, just incase, as that can cause timing issues.
Will report back..
