first bump in the road, P0011 and P300

[ANMVQ]

So was drinking home tonight and I heard the engine pinging!
at 2500 rpms would ping and go away then tech CEL light started flashing them went off? About 10 mins later it stared again light flashing and car lost all power . I had my laptop in the car so hooked it up and found the above codes. I just installed the M370 and Z1 HFCs . I looked everything over bad foun a vacuum leak at the intake ( T hose were the MAP sensor is but not the map sensor that's has a hose clamp on it ) I tightend it down again and put a zip tie on it. reset the code and everything seems to be fine ?
Had anyone had this code before , I'm thinking the random misfire and the intake cam timing go hand and hand , an both are from the post MAF vacuum leak? thoughts ? Thank you
