P0341,would replacing crank sensor under cover next to oil filtr fix this?

What is your question?

P0341 code. On cold start only there is a rumble like the timing chain for a second. Sometimes Cruise control wont work after cold start. Sometimes it does but if it doesnt I shut the car off and restart and it works. but as i drive, the engine light and VSA lights up and cruise is off again of course. Putting a load on it on the highway at first will always light it up again. I had a mechanic try to fix it. He replaced the VTEC valve he said it wasnt actuating. But my problem never went away...??? Another thing is when the eng lite and vsa lights come on.... my diagnostic device also flashes the Evac sensor and Calalytic sensor icons only (with the p0341 code of course)... then I'll clear the codes and when it all lights up again it flashes the Evac sensor, Catalytic sensor AND the EGR and Oxygen sensor icons. And one last question... I need a sticker on this thing in a week. Will it fail emmissions under this circumstance? Thank you and sorry for the length of this...just wanna give u all info i can. -Ray
