HELP! Replaced intake manifold gasket - have problems now.
I just replaced my intake manifold gasket and MAP sensor on my 2000 Blazer. I put it all back together as per the directions. I started my truck and the engine has a miss. The check engine light is also on.

Check for vacuum leaks.
When you removed everything, did you open up the intake plenum or pull it off complete?
Pull the electrical connection to the injection spider and have a look at all of the pins. It is not too difficult to bend a pin.

What I meant by open up the plenum was the removal of the plastic upper intake. If you left that as an assembly with the lower intake, then we can rule out an issue with the injection spider aside from the aforementioned bent pin on the main electrical connection to the spider.
You can check for vacuum leaks with an unlit propane torch.
Also check to make sure you have all of the spark plug wires fully seated onto the distributor and the plugs. I have seen trapped air in the boot cause a plug wire to become disconnected.
