I have heard people having issues after replacing the intake manifold gasket. Mostly by not no plugging something back in or cracking an old vacuum hose. I have a M54 engine so wen I did mine I just replace the old hoses. I have a real rough idle but I just left something unplugged at the end of the sequence. Once I plugged it back in everything ran well. If you were not having the issue before the change I would definitely go over my work to verify everything is bolted down correctly and all plugs are clipped in all the way. If it fixes itself then I am thinking about a vacuum leak somewhere

As to the rest, it seems as though my starter is bad, coils are bad and battery is good. So I'm going to change coils & starter.

In your opinion is this due to a leak on the cover itself? Or perhaps it's that I need to relearn the valvetronic motor using Ista-D?
Also, if i let the car run for a while, the cat gets red hot and glaring.
