Just got off the phone with the mechanic after replacing Crank Position Sensor. On top of the 0171, 0174 and misfire codes, I had a 0335 code and a Trans slip code, I think it was 1878. Anyone know if the 335 and 1878 could be related to the CPK? I researched a bunch of info on this site trying to diagnose it without taking it to someone who would check it from head to toe and charge a fortune. I took it to a trusted local shop, and they told they would start with the CPK. They offered the part at $114, and I found it at the dealer for $49. They charged me $130 for the labor. I haven't driven it yet, but they said they retested it, and there are no codes and the CE light is off. I will let you know more tomorrow.

Thanks to everyone who posts here for all the invaluable information. I wanted to post this to help out anyone else in the same boat I am in. Hopefully, this is a done deal.
<fingers crossed>

I have a P0300 code would that be caused by the Crank Position Sensor. I had first started with the 171 and 174 which the dealership stated it was the catalytic converters. Had them replaced now it has the 300 error codes.

As for the 171/174 codes, everything I have read should indicate the O2 sensors or Mass Air Flow Sensor. The 300 code would have something to do with the CKP, but as far as I know, it is not a gaurantee. Some people have said that the misfires came from the coil pack ignition. My check engine light has come back on, but I haven't had it read yet. My car is not hesitating, stalling or lacking any power, so I think I fixed the misfire, but I might still have a bad MAF sensor, so I am going to the shop now for another scan. I'll let you know what I find out.
