OK. this is my 2 cents.
after 20 years of installing every available aftermarket electronic equipment in cars (4 years of them as the official installation shop of Porsche Israel), i can tell you one thing.
if you worked on something (in your case the cluster) that where the problem is.
problems
usually don't happen by themselves. the chance that a MAF/coil will blow at the same time you were working on something ells, is close to zero.
car was working fine before taking the cluster out. right?
remove the cluster, check the connectors and wires. these connectors are very sensitive and tend to break or loos a pin (ask me how i know).
also take Homeboy advice, and check the ground points behind the cluster. make sure they are tight and none of the wires is broken. some of them are very thin, and can break easily when working in that area.
whit that said, it can also be that you are very very unlucky, to have somethig ells go bad when working on unrelated part of the car.
i truly daubed it.
