I have had no previous problems with my car for the past 4 years. On 11-24-08 I took my car to a shop & was informed with P0300 (Random Misfire). They replaced my ignition coil because my car was not picking up while driving uphill. The car ran fine for 3 weeks 2 days until it started cutting off completely. On 12-11-08 I was warming up the engine and it cut off & again while driving it 5mph. That time it took 3 turns to power back on. It drove fine 3 miles in the am & later in the afternoon 3 miles back. In the evening while on my way to Autozone(1 1/2 miles) it turned off & while restarting, the engine check light came on. I had to chug along to the entrance because it started shaking. Autozone performed the engine check & read 3x P0351 (Ignition coil). Autozone told me that it could have been a defective ignition coil & for me to replace it with another. I called the shop & they stated that it was not the ignition coil & that it must be "several" other things. I have not checked or changed out my air filter in the past 8 months What could possibly be the problem? Do I have the right to tell the shop to replace it with another coil since it has 1 year warranty even though they are telling me it is not?

Hi, it sounds like the coil may not have been first problem. Now the engine stalls, it sounds like the fuel pump was going out, then went out completely, causing the random misfire code. check for fuel pressure when the engine stalls,,
