I got my check engine light checked out this morning at Auto Zone. The guy plugged in the func check instrument and told me I had 17 malfunc's but most of them were duplicates. Anyway, I was wondering if ya'll could perhaps give me an estimate of what it would cost to fix these malfunctions. Here are my problems:- Auto Control System Malfunction- 02 Sensor Bank 1- Knock Sensor Circuit Malfunction- EVAP Emission Perge Valve Fault- Fuel Air Metering

Naw I haven't. It's been on seen I bought the car back at the end of March. I just found out yesterday that they'll func check it for free. I do know that there is some problem with the car tho, sometimes while driving, the car acts like it doesn't want to respond to throttle input.

it would be better to know the exact codes(number), and its kinda hard to tell if not directly at the car but heres a starting point.for the fuel/air metering, id check your O2sensor(takes care of that code too) and clean the MAF. Check the connection to the purge valve, check to make sure your vacuum lines are routed properly with no leaks.Check your wires/routing to the knock sensor/make sure its plugged up.id start with that
