Engine Mechanical problem
2003 Ford Crown Victoria V8 Two Wheel Drive Automatic 125000 miles
Beside the LCM and multifunction switch troubles I have got another little problem:
When I bought the car about 2 years ago (100.000 miles) I realized that the engine sometimes started to sputter at about 30 - 50 mph when you press gently on the accelerator within this speed range but his didn ´t happen very often.
I also realized that the car engine doesn ´t run all round on sloping roads at 30 mph. This happens e.g. when you drive down a hill in the city without using the accelerator. But this was sometimes hard to sense.
I tried to solve the problem by changing the spark plugs, the ignition coils, the air filter and fuel filter. It didn ´t help. No problems when you push the pedal to the metal or under/above this speed range.
I also tried a fuel system cleaner and this seemed to
improve the driving ability for some time but I can ´t
say it for sure.
Maybe the California Highway Patrol used bad fuel? They put on 100.000 miles in 3 years on that Ford.
I kept on driving and ignored the problem. But after about 25.000 miles and during the last few weeks the problems have become bigger:
The Ford sputters now much rougher within the described speed range and this happens very often.
It seems that the idling is also slightly affected.
Are these symptoms for bad fuel injectors?
Your answers are really appreciated!!!
