Default Edit: P0106 to P0108

So I used the scanner to clear the codes, of course it came back. This time instead of P0106 I now have P0108. This is driving me crazy. P0108 says there is map sensor high voltage input. Could this be caused by a bad O2 sensor? The scanner does flash icons for egr, o2, and catalyst.

I'm pretty sure the 0108 was the code I had. I just replaced the MAP sensor. I tried 2 different PCV valves to no avail. They are about 5o bucks for a Niehoff through www.partsamerica.com (Checker/Advance Auto'* online entity) or through AutoZone. I never could find one at GMPartsDirect

Sounds like Moss is pointing you toward a new sensor...could be right.

I've got a new map sensor waiting but, wasn't sure if the seemingly extra amount of oil from the pcv would foul it out. I also purchased a new o2 and egr gasket. Might try to get out tomorrow and change it all.

O2 and EGR won't change the oil on the sensor.... I think the pcv is the culprit here.

I listened to what you said and just changed the pcv, and the light went off for the first time in months. I drove it around town running errands... still no light. I didn't even put the new map sensor in, no o2 sensor, didn't clean the egr. I'm going to let it run for a few days before I try to get my money back on parts. You don't have to say it, I've read it several times on here not to throw money and parts at every problem, but hell I'm new to this and have become very attached to my Bonnita. I'll get those pics up soon of "Rainbow Brite". Also do pcv valves need to be replaced regularly, that one was only about a year old?

PCV and regular changing.....
I have changed them more frequently than annually before and less as well. Periodically (oil changes) I take it out and give it a gentle shake. Rattling sound means the bearing is still free and working. (usually good)
Some people spray it with a little throttle body cleaner to clear any oil or residue on it.
The basic premise behind the valve is to vent the crankcase, oil, gases etc are all part of it'* job.

A 98 owners manual I have says emissions control service should be performed every 3,000, but does not state what an "emmission control service" contains. I would assume the pcv falls into this category.
