I get in the car this am to start the car and I start it up and the car was shaking violently, and sounded like a WRX. MY inital thought was Oh its cold and I'll give it a few to warm up...

No go. The car continued to sound like this and rev like this..
So I pull out and it was stuttering and running and still sounded like a WRX. Im like WTF ! a SOLID 10 min of running and it finally stopped running like ass and sounding like a WRX.

Never done this before.. any ideas ?

 

i think it could be mass air flow sensor, what did u do the night before it happened

 

Drove the car home, No beating on it, no racing nothing..

 

I had a loose MAFS connector once, that made the car do that. It sounded way worse than my WRX ever did. Make sure the connection is tight and also free of water/condensation.

 

Okay.. Ill check that out tonight. it was cold out, and it rained last night too in my area... could have very well been that.
Thanks guys

 

it was also very cold this morning. could be a coolant temp sensor failure or issue!!

 

nissans and they're ghey coolent temp sensors, someone needs to find a way to get rid or eliminate the effects they have on the ecu.

 

tru da-T

 

it could be a faulty injecotr, faulty coil pack


or blown cylinder.

if nothign electrical fixes it, break out the compression tester.

 

Ralph had similar issues due to a bad MAF, hopefully that's all it is
