Title: 94 2.5 beginning to backfire...
Post by: geocachenut on April 22, 2012, 06:39:23 PM

 :'(  Over the winter (I don't drive her in the winter), I had the throttle body bored to 63 MM, changed out the plugs, cap and rotor.  For some reason, when I am getting on the highway (foot to the floor) and changing gears, it has begun to backfire.  I also replaced the exhaust.  Anyone have any ideas what might be going on?

what's the plug gap set at? any O2 sensor issues or any codes?

if none of the above my guess it's a leaky injector

Been thinking on this one if it just started after sitting  there are a couple of things to check.  Moisture in the Ignition system.  Or More like it the fuel has collected Moisture  and this  10% stuff gets is straight out of the Air..
