I am chasing a rough idle now for months.
Engine rebuilt about 15000 miles ago.
Scanmaster #’s are good
Af - 6
L8 - 38
bAt - 13.2
Int - 128
bL - 132
MPH- - 0
CLt - 167
AtS - 121
r - 825
tPS - .44
IAC - 17
Replaced ic module coil pack
Vacuum is 18-19lbs at idle
Cleaned injectors
62 turbo
55# injectors low z
TT chip 5.7
3.5 Maf ls1 with 6.25 translator
Idles rough after at operating temp
Slightly worse while in gear. Checked flex plate and balancer seem balanced
Exhaust leak at crossover has been there since before rebuild-stock-flange.
No leaks under boost test with rockers off.
Idles in open loop according to scanmaster
Runs good under boost. A little KR after 17lbs of boost.
Frustrating shake at idle. Plugs look a little brown
All seems ok but can’t control idle shake.
