Hi all,
Last year, returning from the Parade, check engine light came on. I replaced a used exhaust gasket with a new one and reset the codes. All was well. At a DE last Saturday, just finished a 20 minute session with car idling in the garage, check engine light came on. Same codes. Drove 1 hour home. Next day, reset the codes. Driving home from another day at the track, check engine light comes on again. Car funs fine.
P1128 & P1130 are O2 codes for both banks indicating lean mixture.
Factory manual lists posible causes: Exhaust leak, intake leak, low fuel pressure, low fuel volume.
Before I start replacing parts, has anyone had this problem?
2000 Boxster S, sport exhaust, 40K miles, lots of track time in the red group, but with several long road trips. Original MAF sensor, O2 sensors, fuel pump and filter, air/oil separator. Uses no oil. Not driven in the winter.
