Hi! i drive a 2000 echo 5 door my Engine ping's abit but not all the time could this be just a case of crap fuel or something else? if anyone has any suggestion on what fuel i should run in it or add some injector cleaner or anything else i should do to stop it pingin, will be most grateful
Thanks

If it just started to ping, could be the gas. Try another brand or grade of gas. Stay away from hills (or downshift) or putting a load on the engine as pinging is not good for the engine. Does this car have a knock sensor, the sensor should detect the ping and attempt to retard the timing to stop it. Check engine light on?

the car has only just started to ping so i will try some different fuel and see what it does then. as for the knock sensor i'm not to sure if it has one or not. engine light doesn't come on at all when driving around, if thats what u mean by check engine light on?
thanks for the help toyomoho
