Default catalytic converters are in

It was a relatively easy job, I had the end of one bolt header side snap off. It came loose but got progressively tighter as it came undone. Eventually the end of the bolt snapped off and I will buy another nut and screw it on the bolt that's left.

I checked the cats and inside one it looks like someone tried to massage it to get it to breath?




The other cat looks OK. I still have all the lights on traction, engine and VSC. Also when I went to accelerate past 3000 rpm it chocked.

So I need to check two things. MAF and reset all the codes P0100. also reset the VSC. It could be the Y pipe cat is plugged? If it is I would just cut it out and have a straight pipe welded in.

It was a reasonable job for a home mechanic but I have cuts on my hands and a nut to secure and I haven't solved my problem yet.

I will play with it tomorrow going to bed.
