I have a 2006 lincoln ls with 105,000. My problem started about a month ago when ETC failsafe mode appeared. I had the codes read and it was a bad throttle body which i replaced with OEM. About a week later the car started shaking and misfiring and the Check engine light came on. I had the codes read agian and this time it said it was coils A,B,D,E, were bad. My mechanic checked everything and said it wasnt the coils but the ECM. I sent hte ECM off to AES to have them fix or reman it, but they said it was fine after doing a bench test. I have since replaced all coils and plugs but the car is still shaking getting no fire from the injectors. I don't know what to do next.

Next, find a better mechanic.

Your throttle body was fine. It was confused by the RFI from one or more marginal coils.

Remove all plugs and verify that their gaps are set to exactly 1.0 mm. If you used off-brand coils, then replace those too.

You mention injectors. Injectors don't fire, they spray. Do you have reason to suspect a fuel injection problem? Did you measure fuel pressure?

The better mechanic is def in the works. I'm just guessing here as i'm not as mechanically inclined as most of you are I'm sure. I replaced with Visteon coils which were suggested on here as well as new NGK double platinum plugs. I'm not sure about the gaps or the injectors. I'm just trying to get my baby on the road.

I have had this exact same problem happen twice now, a bad coil on cylinder #4 caused ETC failsafe. after new coil, never had that problem again until coil went out again.

found real problem to be the coil cover's seal was messed up and letting water leak in and was flooding the back coil well.
