I recently checked the diagnostics on my caddy. I was led to believe it was reading "MAP Sensor to to high. So I purchased a new one. However after about 5 minutes of running the engine light still comes on, I have not run the diagnostic check again, it could be another problem I guess. Or do I just need to reset it? Thanks.

Reset it first. If it still comes on, check the codes again and post the exact codes you see. Someone will probably be able to help you with that. Consider posting further responses in the Northstar Technical forum.
