2002 Ford Taurus with 188k miles. At 175k had transmission rebuilt because torque converter sheared. At 1856k ran out of gas, car started stuttering again like before transmission was rebuilt. A few days ago during heavy rain, started my car and it was misfiring. Replaced plugs, wires. Pulled code P0353, replaced coil pack, still pulled code P0353. Tried a second new coil pack, and still pulled code P0353.

Have you checked to make sure the injector is getting power? Have you checked fuel pump pressure? Have you checked compression in that cylender?

Hey guys, thanks for getting back to me surprisingly quickly. I have not checked compression in that cylinder, fuel pump pressure, or injector power yet. Going to test voltage on the connector to the coil pack today and I'll let you know the result. Have tried some fuel injector cleaner, but that didn't seem to do anything. If it was compression, pressure, or injector power, wouldn't that throw off a different code though? Also When I filled up my tank last, I noticed about 2mpg less, down to 22 from 24 roughly for my last tank. Also unsure which cylinders are misfiring, and not sure how to tell which ones are.

It the cylender isn't firing, it will through the code. It doesn't matter if the compression is bad or the injector isn't firing.

Let me know what you find.

The only code I've gotten since I tried the first coil pack was P0353. I've put about 500-1k miles on it since that time. I'll have the codes pulled again tomorrow just to check. I did try an older voltmeter on the wiring to connector for the coil pack, all 4 were the same voltage as the battery, so it's either the connector itself which is unlikely, or something else. The reading I got on the wire, Mind you using a very old voltmeter from my fathers relic car stuff, read 13 at a scale of 50.

Anyway, I'll have the codes pulled again tomorrow and see what they come up with. Thanks for all your help so far.

If it is the same code, try switching the injector with a known good one to see if it changes things.
