Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, welcome to Just Answer. My name is***** you give me a little background on the car? Are these the current fault codes? How is the car running? Has any work been done in an effort to repair the fault codes?
Okay, looking at the fault codes I would suggest the mechanic address the P0303 code next. I suspect that the P0170 code may have been solved by repairing the vacuum leak. If that code is still there you may have more vacuum leaks or there may be a fault with the mass air flow sensor of with the fuel pressure. The P0303 is probably caused by a bad spark plug or plug wire or ignition coil. The P1700 is a transmission upshift delay fault code. The mechanic should check the vacuum box on the kickdown cable to see if it is leaking vacuum.
