My car hesitates to start.
I have a 2003 c240 and it required several mechanical fixes and I took care of everything the mechanic said I needed to take of. When he gave me the car back, it was still hesitating to start. It would sometimes start the first time (but it would hesitate for about 3-4 seconds) and sometimes it wouldnt start (it alwasy started the second time). He said i needed a new fuel pump. We replaced it and it still does the same thing. I informed my mechanic that I was getting codes p0171 and p0174 which indicate something with MAF sensor but he said it wouldn't make the car hesitate. Any ideas?
Thanks
