My 2004 nissan maxima se is shaking a lil bit CEL comes on blinks when I accelerate then goes bk off cones bk on I've replaced cylinder 1 coil pk and plug still skipping grey smoke comes outta tail pipe now replaced the vias control selonoid still no better plz help

 

I've been driving around my girlfriends maxima for a few days and haven't had any trouble out of it. Today I couldn't get the key to turn in the ignition and engaged the steering lock after wiggling the steering wheel. It will not disengage because the key will not turn in the ignition, I've tried wiggling the steering wheel and pressing the break with no luck at all Tutuapp 9apps

 

I've even disengaged the shift lock and dropped it into neutral to try the same thing, still nothing. Any clue what could be going on?

 

Happened to me once. Try rocking the car back and forth. It may not be in mechanical park.
