GTV 3.0

Hmmm GTV V6 lumpy idle

Morning everyone!
Here's the rub: My V6 starts perfectly and goes on to 'choke' and the idle comes down after a couple of minutes as it should. I can, however, feel in the cabin that the tickover is not silky smooth - the engine is shaking under a slight misfire. Under power the performance is fine and all 6 are definitely firing but at idle it sounds to me like it's running on 5. I looked under the bonnet while running and the engine is indeed shaking around slightly and sounds like it's not firing cleanly. Any ideas much apreeshed. BTW idle seems to be at 750-800rpm according to rev counter.

Anything's possible. Even that.

Re: GTV V6 lumpy idle

After replacing the water pump and belt on my V6 the idle has become lumpy, as if it has a misfire. I have tried resetting the idle without success, my next job is the test all the coils etc.
Any other suggestions will be gratefully accepted.
