So my car has been running rich for the past 2 weeks, code p1152 I believe. Something about upstream o2 reads rich or lack of switching, cant really remember at the moment. But anyhow, both front o2s are relatively new, and last week I installed new copper plugs gapped at .54 and the car got new wires after xmas. Friday I put a new MAF on it and disconnected the battery for a while and reconnected it and drove the car for about 20 minutes, mostly highway, a few turnarounds. All seemed well but on my way back to work after letting the car cool back down, it started running pig rich again.
I put a Focus pump in it last summer but it ran fine with this pump in it up until I quit driving it in October. I checked the FPR and have no vacuum leaks to speak of. What should I look at next? I'm really hoping its not a cracked head or something leaking compression causing it to run poorly. The car runs like a champ when on the gas, especially past half throttle, but when coasting or idling you can just hear it drowning in fuel, and the stinch is awful. I even have converters on it and it reeks of gas. Should I try another o2 up front to see if its that simple or does it sound like something else?
Car is a mostly stock 98 btw, timing is bumped slightly via a Sniper tune, has a pypes catted x and magnaflow exhaust, with a K&N filter on the stock intake elbow. Help me out before I decide to park it and tear it down for a carbed C head swap.
