When I start my car (doesn't happen all the time) my check engine light and epc light pop on with car struggling to idle. If I hit the gas slightly they go off and everything is fine. I have taken it to dealership, my husband has hooked it up to code reader and it throws no codes! Not sure what it is or how to fix it, obviously it's not right. Any advise?

Engine light wen on code says is the knock sensor

The camshaft solenoid was replaced to fix check engine light with fault code P0024. Check engine light reappeared after a month with same fault code. I was advised that I now need to replace the timing chain, tensioners, and guides. According to the technician, the timing chain may have stretched a bit because of wear and tear. Which is causing the check engine light to reappear.

when turning volume up it may go up or down.

The mechanic says the valve cover is causing the leak, NOT the valve cover gasket. The cost will be $800, and I think this includes both the valve cover and the valve cover gasket. Does this seem right? Diagnosis says: "Valve cover is leaking oil. Breather system needs replacing with the updated valve cover, vent valve, hose, gaskets, and clips. $800." How urgent would this repair be?

and windows going up and down on its own
