    po132

    Sorry if i posted in the wrong section..so after installing my fast 92/92 my car ran like crap found out my iac sensor is bad so I changed that . Tuner said my driver side o2 was bad so I replaced that ..now a week after I keep getting code po132 which is o2 high voltage blah blah .. anyway I replaced the o2s twice with densos and boshes still get the same code.. no wires are frayed and no fuses are blown . Anyone have any ideas ? I have the polluter cam fast and headers

    Do you have access to a scanner that will allow you to watch live engine data? Did you reset the SES after installing the new sensors?

    Like PAjeff02 said you are going to need to watch the o2 graphs, do you have the more advanced autozone actron one? The one that allows you to graph the o2's, there is 2 things that could be going on, somehow the o2 wires got damaged during the install or something didn't go right during your install of the intake.

    Did you install new gaskets when you put the intake on? Did you torque the intake down right? 44 inch lbs then 88 inch lbs I believe it is without looking it up.

    You might have an air leak on one or multiple cylinders causing a lean condition in which the computer will command the engine to run pig rich so it doesn't burn itself up.

    Throwing parts at it isn't going to help. Especially since this started right after you did the install of the intake. You didn't happen to damage the fuel rail when you transferred it, did you? Technically the o-rings are supposed to be replaced, but you don't really have to. You just have to be extra careful not to damage the injector tips and the ceramic disks on each injector.

    Did you swap out the bolts on the valley plate? If not, you may not have a good seal against the heads and could be sucking unmetered air into the engine.

    The valley cover bolts should have never been touched with just in intake swap. So that would be kida of odd.

    Not 100%, but I thought that the use of button head bolts was required to gain additional clearance. Anyone?

    Did you pick up this intake used? Were the required low profile bolts sent with the intake. They are a MUST other wise the inake will not seal to the heads causing all kinds of air leaks, and very poor running conditions.

    Lots of questions so ill get started lol 1. The valley cover bolts are from fast . There button heads . 2. Brand new gaskets for the fast ,internal and external 3. Fuel rail never came off and fast 36 lbs went on(came with orings) 4. New fast was torqued down as ls1how to.recommended in a 2 pass fashion 5. This started happening after the fast and new tune I never had this prob with the ls6 intake so im guessing it.might be the tune . My o2 wires look fine there no where near my longtubes

    This might sound a little silly but when you had it tuned did you let your tuner know you upgraded the injectors to 36lb so he could adjust the pluse with of the injctors?
