I found the MAP sensor, right at the front of the engine and something easily accessible for a change. There is a vacuum hose that connects to the back of the sensor, and mine had small cracks in it where it connected to the sensor. I snipped the end off, being careful not to cut too much as its a short hose, and reconnected. Ran the engine and it actually seems smoother. So maybe had some leakage going on as well. No codes. Gonna run her today doing errands and whatnot so lets see how she does.
