Pinging noise coming from engine, have taken vehicle in twice with no resolve. Bought truck new in Jan 03, have 29,000mi on it. First they replaced the maf still heard noise, then second try they reprogramed the computer. Service manager stated it might be coming from fuel injectors. Sound heard on acceleration at all speeds greater under load.
I have many problems with my 2003 Ford f150 from engine noises to transmission leaking and slipping. My vehicle has been in twice now and nobody at Fords or their engineers seem to know what is wrong. Fords does not know what to do. I would greatly appreciate if someone could look into this matter because no one should have this many problems with a brand new $30,000 vehicle.
On a cold start up vehicle knocks every morning. Has been to Ford dealer 5 times. They have told me numerous things, like use heavier weight oil, no problem, we hear it but not sure what it is, we hear it common engine noise. Problem still exists. First time I took it in was 4/2003, and vehicle is at dealer now again.
