Ok I am at a loss here. I have a miss/pop between 5+ boost seems to be only when I get into it quickly.
I Have replaced the plugs, wires, coil pack(top and bottom) MAF,O2 sensor, fuel filter, fuel pump,(fuel press is 1lb boost-1lb fuelpress) reset cam sensor,reset tps & IAC, checked for vac leaks, pressure tested intercooler. All sensor values look good except o2's are all over at idle and at cruise as low as 080-980 mvs. sometimes the car will rev to 2000rpm when you come to a stop and sit there for a min till settling again. idle is rough motor shakes. though at times you punch it an it runs perfect. when it pops it does not leave a smoke plume leading me to believe it is a lean pop. Any guess on what I should do next? car ran great last fall with fresh rebuild just started this in spring. Thanks in advance to all who help!
