Hey, I can't tell what is wrong my ls1 runs like crap. The o2 went bad. I bought some cheap ones and they both stay at .5v and never move and eventually throws codes.

What is fucked up is that even when I change tune to force closed loop it still idles like crap. It runs fine driving and acceleration is fine even part throttle but it won't idle right
When I unplug the maf it runs smooth but idles really high. I cleaned maf and I also have a backup maf and it does same thing with both of them.

Closed loop is WITH O2's working. To leave them out you need OPEN loop.

yah I always get it backwards thank you

When I removed the emissions crap I put some vacuum caps on the TB one of them came off

That's why it wouldn't run even in open loop
When I was scanning I noticed the iac wasn't doing anything so I bought another one and reset the tps and iac
How long before it learns the damn idle??? If I set the iac with hpt it idles smooth as glass

random-strike

It idles fine and smooth in gear. But in N or P is bounces around

Sometimes it'll sit at close to desired rpm then start bouncing again


Very annoying

random-strike

Maybe it figured something out the idle is only bouncing about 50 rpms now
iac only moving a couple in each direction.

Ok as I'm typing this is started bouncing again wtf

random-strike

idle never would be smooth with the new iac.

i put the old one back in and it works fine, took other one back to parts store
