Just bought this vehicle initially I was getting p2647 code and vehicle drove ok for a day. Since then if I drive the vehicle for 2miles vsa lights comes on and engine stops. I believe vehicle is going in limb mode. What I have done so far to fix.

Step 1 replaced the solenoid gasket. (Got new p2649 code and random misfires. Engine oil is burning was almost empty.)
step 2 replaced all the coils and plugs did oil and filter change (drove 4km same issue vehicle went in limb mode. Again. System was still recording misfires)
step 3 added muzzuler mod 100amps resistors. And replace oil pressure switch(Drove for 4km and same issue vsa light came on and engine goes in limb again and now I only see p2647 code.)
vehicle is burning engine oil as I do see blueish smoke and lots of moisture. Not sure why p2647 is still showing even after replacing the sensor and oil level are good. 5w20 mixed with Lucas engine repair.

I am thinking vtec is causing issues so is there a way to disconnect vtec. So I can at least drive the vehicle for more than 4km. And run the vehicle with all 6 cylinders as well.

Thanks
Ps I paid 6k for this vehicle have only 191 kilometers. Need to fix it so it last me through cold Canadian winter.
