S13 backfiring, runs like sh!t

[Wildebeest]

my ls-vtec backfired almost everytime i shifted and almost all the time wen gearing down coming to a stop. ran fine though and definately no loss of power.

I can live if it was just backfiring, I love it lol. but the problem is that my cat is glowing red and shooting flames from my pipe. lol . I was told that i might have an injector runnin wide ass open, causing it to dump too much fuel into the motor, it burns it and the excess fuel is causing the cat to get hot? sound familiar to anyone?

no im not that Rob.
Its hard to diagnose a MAF, but first things first, check the inside and make sure that the little fillament is still intact. If it is, you are more than likely going to just have to replace it and see if it is. If its not intact, then you know thats your problem. So you may have to guess and check

MAFs are not hard to di-ag if you know how to di-ag them. why are you in this section?

if your cat is glowing red that means its getting way way to much fuel. why did you just change out 1 injector and why. sounds to me like you have a injector wide open all the time. which is either a stuck(highly doubt it) or a short causing it to stay wide open.

does your exhaust smell like raw fuel and your cat still glowing? they you are running stupid rich.

you might want to have someone that knows what they are looking for help you out and look at the car.
