2003 V8 Explorer problem
My story so far....
I have a 2003 model V8 explorer and from day 1 the engine has a pinging noise on occasion when under load. Problem is that every time I take it in to ford I can not reproduce the problem
About three weeks ago at 87K (service due at 90K) the "Check engine light" came on and the car was running rough. Took it to Ford and they serviced the car and said the light came on due to a very dirty air filter, This was replaced as part of the service.
That day on the way home the car started running rough again and the next day the light came back on. Took the car back in and got it back three days later. This time they replaced the oxygen sensor.
One week later the light is back on, They can not look at the car till Wednesday.
I am in Sydney Australia, Has anyone had an similar experiences? Can anyone tell me what to expect next?
Thanks in advance.
