Ill look for a leak. I have the timing I think dialed in. Smog guy is super cool and is letting me use the bay. But i think i do need a mew cat. Nox isnt really any better. Does idle better.

 

How does it idle, is it smooth? TPS might need an adjustment, if it doesn't know it's coming off idle the fueling might be wrong

 

Is smoth. But i just looked though the van form and i think i solved itx i had ir adle smooth at 750ish when in park. Vam form says it should idle 1200 in park at temp. Adjusted it and made a run and now the nox is way down

 

I think it needs a cat. Timing is on. Idles fine. Passes nox at 15mph just barley and doesn’t pass at 25mph

 

If it has dirty injectors this can happen too. How's the upstream O2? It isn't heated so it needs to be hot to measure right. If it cools down it will throw everything off. It might be old and fouled too.

 

So, should I ask him what his million dollar idea is?

 

Ask him

 

You should respond "Negative"

 

Its missing the bvsv. Someone by passed that with just a hose because the top of the bvsv is gone

 

Also yeah i wanna try the 02 before doing a cat

 

Yeah these old systems didn't have a heating circuit for the sensors. You had the engine and exhaust nice and hot when testing with those latest numbers right?

 

I was at the smog shop for about 2 hours and the van was on most the time and made like 10 runs. So I think it was hot.

 

Interstate running high rpm for 30 minutes, but 2 hours and 10 runs.... Well how long is a run? Couple minutes? You really do want the exhaust hooooot, but I imagine the dude would've known that and you as well. I've had it make big differences in my tests in the past

 

Rip

 

Your cat isn’t that old, it was replaced a few years ago.

 

Oh its not even there? Yeah okay, that can affect things

 

Thats why i don’t really wanna replace it right away. Maybe a new 02 and bvsv will fix it.

 

That valve will have to be there for sure, unless they have the vacuum hoses routed in a way to do a delete? Can you even do a delete of that thing?

 

I just read ip on it. Its design to not allow gas into the throttle body till the engine is at temp. If you by pass it it will allow gas all the time

 

Alright I put in an order info request for custom Alcan springs. 3rd times a charm and I'm gonna do it right. Sick of dealing with shitty leaf springs
