Lincoln Town Car engine acts like it's misfiring when cold on acceleration.
My 95 TC (Big Granny) has 270K. Lately the engine acts like it's misfiring when I first put it in drive in the morning. At idle, it runs smooth with no problems, only on acceleration when it's first started. Once the car warms up, it runs fine. I have replaced the spark plugs (I used Motorcraft) and today installed new air filter and cleaned the MAF sensor. The car still has the issue. Where/what do I try next? Thank you in advance for your assistance.
