Hi,
Over the winter I've been doing a some work on my 8v Gti digi. Its been dry stored in the garage. When I started it after 5 months, after spluttering into life after a couple of attempts, (expected) I noticed it idled at 1250 rpm. It used to be 850/900.
What could have caused this? The stuff i've done to the engine was:
Clean out air intake hose.
Spray carb/injector cleaner into the inlet manifold.
Change the timing belt and tensioner (have I got it a tooth out?).
Replace the hot air hose that goes into the bottom of the airbox, the old one had holes in it.
Thanks
Nik
