I recently bought a 05 murano . I get a #5 injector code and a crank sensor 1 code. Has 149K miles. the car started to shake the steering wheel pretty bad when accelerating from 40MPH .Let of the pedal and goes away. slowly step on pedal and no shake.. I ordered that parts and was told it may be transmission problem also but no trans codes. I only put 175 miles on and want to fix the car up right as i love being able to see all around me. The CVT trans is all new to me also. Never had one . Im an old fart and pretty good at repairing my rides . Can anyone in the know tell me if its possible trans is going south. Fluids are up new fuel pump installed
I'll tell you a lesson I learned, that the codes can be miss leading at time's. I have a 10 Murano and it started running crappy and the check engine like illuminated so I had it scanned and it said a couple different things ( can't recall at this moment, it was like 2 years ago) that were pretty costly but it ended up being a large split in the exhaust intake line at the rear top of the engine and cost me just at $300 to repair, the part was 200.
So I suggest you check your hoses especially the one that look like an accordion.
Also not sure about the Murano but I had a Cadillac that the catalyst went bad and caused all kinds of other codes to pop up and it ran like crap, I was lucky to get it up to 55 mph and make it home and to a repair shop.
Dint know if you know this or even if the 05 has the CVT transmission but mine does and because of the codes it read when it was just the air intake line split the dealership thought the transmission was going, they are known to go out at 130k miles and cannot be repaired, they must be replaced. That's the bad thing about CVT 's.
