ok so I have a problem and I can figure out what it is, I have a 2004 300m special with 92000 miles on it about 3 months ago the cel light came on and the car started idling funny and a couple days later it just wouldn't stay running it would start and shut off after about 15 secs, did the key dance to get the codes and it gave me p0129 which is low barometer pressure and p0122 which is for the tps sensor and one for the camshaft sensor I forgot what it was, anyways I changed all those sensor except for the map sensor and it worked perfectly from then on, well now the cel came on again and now it only gives me p0129 and p0122, this time it when the engine is cool it starts and it will stall and but if I give it a little gas it will stay on and run fine unless I leave it at idle for a few mins then it will shut off again, but it runs fine while moving except the throttle is kind of jerky when u step on it and when you come off the gas pedal, anyways this time I changed the MAP sensor and the cel went away for a like a day then came back and it is doing the same thing but sometimes it will go off again and run perfectly, so I don't know what it could be now, anyways I hope someone here could help me if they have seen this problem with this engine before...I have read somewhere that it could be a vacuum leak, or bad connection at the map sensor, but im not sure so please someone help me out I would really appreciate it thanx

 

also the cruise control wont work when the check engine light is on
