my crx back fires every time i let off the gas if i dont put it in nuetral.

Ive replaced the dist. cap, rotor, wires and plugs. Still no luck.

Any ideas?

 

Maybe Ur Car Is Running Too Rich.. Are U Running Stock Fuel Pressure

 

i run 110 octane leaded race gass everywhere i go and mine does the same thing because it is runs rich.... is it a little backfire or a big boom...... are you running an open exhaust?.... if you are and you are just a little rich then you will backfire..... just my $.02

 

how big is your exhaust? what engine?

 

its a d16. magnaflow exhaust with 4-1 headers. i always use premium

 

its a big boom and stock fuel pressure.

 

I've seen this on 2.25" and bigger crush bent exhausts, is yours a magnaflow exhaust or just a muffler? Also sounds like maybe you should check your o2 sensor if you're running too rich. Do you ever get code 1?
