Maybe, you should check that. Take it a muffler shop if you want them to check it.

Or if you have an OBDII Reader, unplug your cat and run your car for a couple of minutes. IT WILL BE LOUD ... but if the headers don't turn red, and all you get is the 2nd O2 sensor issue, then it's your cat.

And the code for the O2 sensor would be because you would be doing this test with out the cat in.

Tom said if it was the cat it still would start normal!??? This Sucks lol

last time my header glowed red hot was because of the IACV being stuck open.

Was it hard to start also? Mine will turn over for about 10 seconds before it actually fires up! How would i fix it if it is sticking?

take it off the intake manifold and clean it.

also your hard starting could be your battery how old is it?

Things that would make it hard to crank and make the header glow at idle

To little fuel or to much fuel ( this can be checked with a fuel psi gauge and a scan tool)
To little or to much ignition timing ( this can only be checked with a scan tool)
Cam timing off ( this can be checked by setting the cams and #1 Cly like your going to install a new timing belt )
Vac leak but this would also cause a very high idle , like above 2500rpm (this can be confirmed with a scan tool or checking every vac like for issues , this I do not feel is your issue)

I have never seen a CAT cause a hard cranking or a header to glow until you put a load on the engine
I think he is either running very lean , overly rich and burning the fuel in the header(rare) or has a valve open when it shouldn't be from cam timing issues , these are the most common then it gets complicated

I will have to check into these! Thanks! And my battery is new...it doesn't turn over slow it just takes awhile to fire up! Would a blown intake gasket cause any of this?

I heard that maybe a cracked block could also cause similar issues?

I cannot rule out a blown intake gasket because that would cause a Vac leak , very right rpm when it did start but wouldnt think glowing headers from an intake leak

I have a few questions and would be easier to phone can you give me a call this evening
