I have a 94 Lincoln Towncar and after a radiator replacement I have had a
problem with the engine back firing at COLD start up. After less than 5
minutes it will run smoothly all day but the power seems lower than I
remember. It takes several HOURS, usually over night, for the condition to
return. I do not mean winter weather, I mean cold engine.
Two mechanics have told me the mass air sensor was bad according to the
computer. However, neither would guarantee this would solve the problem.
I feel they are guessing and tossing MY money at it hoping something will
Its not the cost but I don't pay for guess work. The Lincoln dealer would
replace the sensor for 285.00, but if that didn't fix it, I was stuck with
the new sensor and they would TRY something else. One mechanic tried a used
mass air sensor with no change in performance.
Yesterday I looked and found one two wire connector on the drivers side,
under the power brake, that was unplugged. That seems to have helped. I
suspect at the radiator repair time something else was left unconnected.
I'm not a full time mechanic but I have turned a few wrenches in my day.
Any suggestions please. Ed in Pittsburgh.
