My buddy has a 93 Trooper with a 3.2 V-6. He is having a problem in regards to the following.

He has told me that it idles great, and for the most part runs well. The issue is that under acceleration, the engine bogs down and black smoke pours out of the exhaust. The check engine light comes on as well. Can you guys give me a check list of things to check? I am fairly inclined, so don't be afraid to get a little technical. Thanks!
