Okay here is the deal, I have a 03 boxster with 44k miles.  I had a complete tune up last week but the check engine light is still on with 3 misfires.  We agreed to look into this next week as I had a short trip this weekend and needed the car.  After the trip my check engine light is still on and when I come to a complete stop it starts blinking, then I go and the light goes off until I come to a complete stop again.  I went to Autozone to check the CEL's and here's the reading.  
 
 
306
304
305
misfires
112   Intake tem. IAT sensor 1 circuit low
102   Mass or volume air flow sensor circuit low input
1341 Camshaft position sen. a no signal over 600
327   Knock sensor 1 cir. low input bank 
1325 Igniter cir. malf. no. 6
Is this car even worth keeping?
