at low rpm up to 2500 rpm engin back fires , mostly when you gun it. any tips were to look

 

what engine?

 

Spud,

What's the last thing you did before it started doing the backfire/miss ?

Or, did it just slowly go way out of tune ?

Check to see if the timing is right and then start looking for vacuum leaks - if those are okay, pull the plugs and find out which one is missing (it will be darker than the others).

If that doesn't work, write back.

Good Luck.

with no more info than you gave best thing you can do is check for codes and make sure you have a good tune up and then go from there.
