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.

    With that many miles, it could be so many things. I believe your car is OBD-II complaint, so hook up a scanner or code reader. Also check for vacuum leaks in your PCV hose, especially as it runs back to the firewall just before it makes its connection to the intake plenum.
