Please help me fix my C32
I was driving my girlfriends car home from work today and I had driven about 15 miles. I was cruising about 55 mph and all of the sudden it just cut off. I coasted up to a stop sign and put the car in park and tried to restart the car. It started and idled horribly and then cut off again. I tried this a few times with the same result. I left the car for about two hours and went back and got it. It cranked up and idled bad but it could be driven. It was only about one mile to the house. I have been searching the forums and I have come across suggestions from the crankshaft position sensor to plugs and wires. I checked the codes and it listed multiple codes. P105(map sensor) & P300-P304(misfire of cylinders) The car was running perfectly until it just cut off earlier. Any suggestions on what I should check now. I am really at a loss. Sorry for the long post but hopefully someone can help me out.

Thank you for your prompt reply. That is what I had originally been leaning to before I ran the codes. I had read about how they tend to fail once the car warmed up and once the car cooled down they would work correctly again. Would it be a good idea to let the car cool down completely and crank it again? Do you think the car would run correctly until it warmed up?

it should be. unfortunately the s/c engine only takes about 5 mins. to heat up and it may fail again. hopefully someone else will chime in as im only guessing. the codes certainly suggest some sort of timing irregularity

I went out this evening and cranked it up. The car had not been cranked in over 24 hours. Same rough idle and the check engine light came on immediately. It gave similar misfire codes and the map sensor code again. It also gave the malfunction about the battery/alternator needing to be serviced. Could this still be the crank position sensor? I will not be able to really check over the car until this weekend. Is it worth it to buy the cps and the map sensor?

CEL with MAP code thrown. Misfires were not saved. Probably pending... I got it resolved right away, so it didn't have much more than five minutes run time with the vacuum hose disconnected. By the way, it did throw battery/alternator malfunction too! I think you have a vacuum leak, and you should really check the vacuum line at the rear. It goes into the rear passenger side of the supercharger. Does the problem lessen as you gain speed?

I had a similar problem a couple of weeks ago. I replaced the MAP sensor, but it didn't fix it right away. Gramma_Benz gave me this suggestion:
Try this:
With the car off and the key out, Unplug the cable going to the throttle body, it's right on top. Wait one minute.
Plug it back in, put in your key, turn to position two and wait one minute.
Start your car.
The first time I did it the car started fine. On the second start, it was havin the same problem again. I tried it again, checked all the vacuum lines, disconnected and blew air through the 2 hard plastic vacuum lines that run from the front of the car under the supercharger, and everything has been fine since then.

Look down in this groove, and you will see the vacuum line. It's connected as a pressure fitting. The solid pipe is held in place by the rubber piece... Not to say this is your problem, as it could be another line, or something else completely. This line is what caused the same exact issues for me though.

A little update on the car. I have replaced the crank position sensor, the map position sensor and the camshaft position sensor. Cylinders 1, 2, 3 are not getting spark. I swapped the three coil packs from one side of the motor to the other. I also replaced the spark plugs. Cylinders 4, 5, 6 are firing as I would assume the should. What would cause the coil packs on cylinders 1, 2, 3 to not fire at all? Is there a fuse that could be blown or a connection that could have come loose? I am open to any suggestions. Thanks.
