Detail: My 2003 crown victoria p71 pings on accelleration. 2 weeks ago, the entire egr system was cleaned professionally - twice, still pings. Last week a professional Crown Victoria mechanic (works for a police dept) replaced MAF sensor, still pings. New plugs and boots last month. EGR and MAF readings on his computer (mobile device which reads at various speeds - he rode along with me and took readings) read within proper specs at all speeds. I am using regular grade 87 octane fuel, which is what the cops all use. 114K on car. Any suggestions?
Solution: Check the timing. It may be off slightly. I would up the octane on an engine that big too. , Hi, a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.
