got another car 95 fleetwood with lt1, all stock surges at idle...

on my scanner everything seems to work great o2 are active and fast, tps map maf all is good..the iac is causing the surging going from 45-125 it starts this after 180 degrees...it stays around 190


this car has 2 dtc...11 for the mil light circuit the other is for p0029 air pump


and witha regular dmm the opti between high and low referance signal reads 4.9 high and low of.006 volts



well i let it sit and idle a while this morning and got some codes...im afraid are intermittent and the reason the mil light doesnt work
11
22
29
33
34
48


checked fuel pressure its stabile at 36 at idle(little low?) and right before it revs is starts to go on the fritz from 33-39 with the vac line off its 45 solid...did a volume test and its fine

had some spare time and parts and swapped the maf/tps/iac,cleaned its passage/map/icm
problems still there...

lt fuel trims are 125

im going to pull all the plugs and wires and ohm them in a minute when it cools...idles smoothe for the most part

i also unhooked the aftermarket stereo(fuse) and voltage stays above 13 at idle

topped off the tranny fluid and oil

blew compressed air into the opti to cool it see if that helped

blocked off brake booster vac hose, evap, and pcv valve
