#7117, "RE: Strange fuel trim values.." In response to In response to 11
Originally posted by XtremeRS Yeah the o2 cycles lean and rich, just like it should(its a new o2 sensor as well). I DID run the base 37 psi fuel pressure without the vac line connected at first, which brought the idle fuel pressure down to 27-28 psi like it should, so the FPR is working correctly. But when the pressure was that low, all my trims were maxed out at 139%.. wierd!
Well, im out of ideas. Is it reaching operating temp? Maybe its stuck in closed loop and those are the warm up enrichments...dunno
