My buddy hellraiser here on the board is fighting with the PCM. He can't get his idle AFR to go stoich.

What steps does he need to do to get his idle afr to 14.6-14.7 or in that area.

His cruise afr is good and his WOT afr is also where he needs it to be.

If anyone could help and list what steps he needs to take to get his idle afr lined up that would be awesome.

Set up, stock block, heads, turbo kit...bout it.

Thanks Jer!! I'll get it figured out some day. You guys think a bad o2 sensor would cause this?

what is your a/f going to at idle? Maybe the motrons are too large? Id talk to ken at hpt I think hes helped a few people get their idle in line...also are you running maf or SD 2 bar?

big injectors can cause a shitty idle if the proportional tables arent set up right. they can inject too much fuel to force o2 oscillation and cause the car to be rich. if those are inline, your o2s can be slow and thinking its too lean. but normally if the proportional closed loop fuel is not in line it will cause the o2s to oscillate slower and dump too much fuel. u can try to turn off prop idle. also what timing are you running at idle? and what is a full list of mods?
