Cars, don't ya just hate them?
I have a wonderful land cruiser it's a 1996 Mercury Grand Marquis.
Big, comfortable, powerful, fairly nimble for its size, 27 mpg on the highway and about 20 in the city. Not too shabby.
Only real problem I have had with it other than a poor design on Fords part of the PLASTIC INTAKE MANIFOLD which has a water passage built into it and it tends to crack in said water passageway..... oh and the heater core had to be replaced which entails the complete removal of the entire dashboard.... there is the little problem of it not wanting to maintain an idle.
Not all of the time. Not only when it is cold. Not only when it is cold outside. Not only when it is raining. Not only when it is hot. Notonly when it is hot outside. There is no rhyme or reason as to when it decides not to idle.
Sometimes it will run for several months at a time with no problem then the next time you go to start up it will not idle.
Today while searching the internet for clues as to what the problem may be, I stumbled across a possibility. There is a thing called the air bypass control. It controls the air bypass for idle speed.
It is supposed to be cleaned every 25000 miles(its only 110000 overdue).
I pulled it off the engine and checked it out..... full of carbon deposits! Stuck wide open too! I gave it a good cleaning with some carb and choke cleaner and WOW IT WORKS!
Wish I would have found this out about 3 years ago when it started acting up......
