Fire Shoots Out of Down Pipe/ Cat Solid Red!?! Please Help

pull that light son

[James Matteu]

The check engine light only came on after the cat was removed, it is likely the code will be for reduced catalytic function (HO2S showing too much fuel, no cat function), but pull the code to be sure.

You should test the Ignition Coil, unless yours is internal and came with the distributor that you just bought.

Will pull that code tomorrow after changing everything, it's external and I will be checking that as well sine I have 2 extra ones. I'm also gonna replace the injectors just in case. O2 sensors can't case this can it?

ummm, buddy...OBDI doesnt know whether you have a cat or not. There is no post o2 sensor. i ran no cat for 1.5+ years and never had a o2 CEL and was running a universal bosch o2.

you must be thinking of P0420 which is catalyst inefficient or post o2 signal low (rich)

Before you replace anything, pull the code because it will give you a direction.

Not an expert but here are some thoughts

1) misfire in one cylinder could lead to dumping lots of unburnt fuel vapor into the exhaust manifold, where it can easily ignite and fry your cat and I would imagine your O2 sensor too.

2) check your ignition timing. Make sure it is within +/- 2 deg of 15 deg before tdc. I don't really think this is your problem though I thing your problem is (1), (3), or both (1) and (3)

3) If your o2 sensor is fried or fouled, and I can't imagine that temps like that wouldn't fry it, or if you melted the wire off of it or something extreme like that that I don't even know is possible, then the ECU is gonna constantly be dumping a very rich default mixture (intended to prevent detonation) and that could be your rich mixture problem right there.

this is what I was thinking, it could be caused by no spark in one cylinder or one or more stuck injectors

^ Listen to this guy, he summarized my points as well.

Thanks for the help guys, but god fixed the problem for me :



She will be missed

[batever]

That's nothing, fix it! get the engine running right, then once you know it's running right have the bodywork done.

Ok, well, whatever you decide, good luck!
