Check engine light had been on previously for about a week. After my girlfriend got gas the car started driving bad. The check engine light was flashing during this time. We parked the car for a week and yesterday I changed the spark plugs, oil, oil filter, and cleaned the throttle body. Started up the car and it's still driving bad, plus check engine light still on and blinking when driving. Went to autozone for a computer scan and got P0306 and P0014. This morning I went to the ABC salvage and got a coil and swapped out coil on cyl 6. Problem still exists. Some of the other things on the autozone printout is vacuum leak, injector fault, high or low fuel pressure. What is probably the next thing that should be checked and how should it be checked. I don't have a vast amount of experience when it comes to diagnostics. Any advice will be helpful. I purchased the coil from the salvage yard, because I don't have unlimited resources to throw at the problem. The coil appears to be in good shape and actually looks better than the one that I removed (I understand looks don't mean everything).
Any help is appreciated.
Thank you
