Thanks Ricardo, I'll see what Air Care Tech says first since that's free.

Good plan. If you are running too lean or have too advanced timing you are asking for trouble if you don't get this fixed right. As in cracked pistons kind of trouble.

The Toyota rail fuel delivery hole is M12x1.25, but it uses the pulse damper in place of a banjo bolt. The cold start injector banjo is M8x1.

Kind of like this bolt for Honda banjo bolts at the fuel filter:



Who knows, maybe this fits? Is the 3FE banjo bolt a 12mmx1.25? You would need a fuel pressure gauge w/ 1/8" NPT thread.

Hi Chris I like to see cat temps around 250 to 350 and the cat should raise in temp from the front to rear between 50 and 100 degrees if it is working properly. Good luck

Thanks Art, IIRC there was something like 180 degree change front to rear but I don't trust my memory enough to say that's what Scott told me. I do recall his 130% comment though.

There is the damper at the inlet end and then the FPR on the outlet end, correct.

Too bad the cold start injector bolt is M8... I really want to get a fuel pressure gauge on my rail. I wonder if there is room on my rail to tap a hole.

Thanks for letting me play in your thread Chris!

Quick update - Air Care Tech found:

1. A bad EGR solenoid. I guess when I found the bad EGR valve I stopped trouble-shooting. Didn't really matter, hardly changed the NOx reading when I replaced it.

2. It appear to be running lean - not sure how to resolve that yet.

3. Recommended going back to dual cats,

Scotty is warrantying my year old cat tomorrow. I really think that may be the problem but I claim total ignorance and frustration at this point.

If that doesn't fix it I have an appt at Colorado Car Clinic next week. I stopped in there and Dave (IIRC) was good. Not very surprised to see another "Land Crusher" outside his shop.
