Should I just say hi here and ask questions elsewhere?
Well, title pretty much says what is going on. I am getting a multiple cylinder random misfire on all cylinders. I also get a rough idle bounces between 400 and 600 out of gear and is very rough. Will cut off when coasting to a stop. Other times it will idle between 1000 and 2000 revving up and down. I am at a loss.
Here is the history
Car was running rough took it to a shop.
1: shop replaced O2 sensors
and informed me of a leak in the upper intake and that I had a bad ECM
2. I replaced the ECM
3. put in a new intake gasket
4. put in a new throttle body gasket
5. cleaned out the intake and the head(lots of residue)
6. fouled the plugs when I tried to restart the car (so I replaced the plugs)
7. new air filter
8. new fuel filter
FYI - last year the coil packs and the ICV were both replaced. When disconnecting the TPS, the car still does not idle properly.
Any help is much appreciated. Could there be some hose or something that is not connected properly from when I replaced the intake gasket? I can not find anything...

Reason: Want to know if this is in the correct forum.
Fairly confident there are no air leaks in the intake, I have replaced the elbow and all of the gaskets and I have done the carb cleaner test and do not get any changes to think it is sucking in any of the carb cleaner.
