Here's the deal. I have an 05 Lincoln LS. I have had a check engine light for the past 12 weeks. The primary code is misfire on cylinder 5 followed by cylinder bank lean, random miss, etc. The car only misses at idle and still gets decent fuel mileage on the highway (around 25mpg), so it hasn't been a top priority to fix.
All the plugs and coils have been replaced by me in the past 2 years. In addition to that, I have replaced the plug and coil AGAIN on cylinder 5 as well as a new fuel injector. I also tried putting in a new MAF in the autozone parking lot (they were nice enough to let me return it after I noticed no improvement.).
After sending a text to my mechanic he thought there was a possibility of a slightly bent valve or tired head gasket. I have yet to do a compression test. What are your thoughts? Again, the car runs fine while driving and doesn't seem to be down on power.
