My engine runs VERY rough.
It shakes the whole car, the intake makes alot of sucking noise
the exhaust manifold gets red hot, and it backfires.
This all happen after I changed the sparkplugs and wiring and took off the intake manifold and put everything back together what could it be?

Double check that all wires are in good shape and have a good connection. Sounds like the engine is misfiring really bad.

Jr. Samples and 88GTman you were dead on. I was talking to some people while working on the car last night and I was trying to get it done so I guessed I must have crossed two of the spark wire plugs and two of the cylinders were firing at the end of the, what was suppose to be the power stroke and the hot gases were flying right out to the exhaust manifold making it red hot. But yeah I just moved to wires around and started it up and it purred like a kitty :D Thanks every! A quick example of how a simple mistake can make a big problem! I will be sure to label everything and pay close attention.
