Have this car in at mo, has very poor idle runs very rough, hold the revs up it runs ok but still high CO%.
Readings are as follows
CO% 6/7 on idle MAP 80kpa on idle 5 inHg on idle (Vacuum) very low? Its had a brand new throttle body and new exhaust manifold due to large crack between 2 & 3. Only code that comes back is for idle correction, probably due to rough running.
its the big 2.2 lump, not nice! I am begining to think cam timing, but the engine is very quiet. Any Ideas? Regards, Jon
