i realize that, reason i said out of frustration i turned it up, until i figure out the problem.
and i wish it was a simple vac leak, i even checked all what? 2-3 vac lines? its not. i have between 5-7 in/hg of vac as stated. my turbo 2.2's had a ton ov vac lines from the factory, ive replaced, simplified and rerouted a hundreds of feet of vac line over the last 11 years on mine and car club buddies cars. ive done the obvious tune up and testing what would be likely, im getting stumped.
my dad has an old 6ft tall green and black screen diagnostic scoping machine, but hes an old carb/distributor guy, can this be hooked up to the ign coil system? if so, how and where does it hook up?
heres what the scan tool logged as the misfire was detected at wot from a stop
fuel sytem: OL
load %: 100.0
engine temp: 180f
shortFT1 %: -.08
longFT1 %: 5.5
map in/hg: 7.4
rpm: 4947
vss: 37mph
maf lb/min: 19.629
throttle position % 100
any helpful advice is appreciated. could it be a clogged cat, MAF on its way out? glitchy ignition module? it runs fine cold and acts up randomly when warm, usually predictable when it does, hard acceleration from a dead stop and uphill 45mph cruise as the load comes on.
