Ok so i recently have been having some problems to know end. Only 1 problem and its been the same thing but i cant figure it out. So i have been posting to know end with no help yet until someone told me about this perephery patch and with it i can disable my egr and o2 censor and many other things.

I have been experiencing this weird problem with the car running right. It has been running extremely rich. I have been working with sum1 recently tuning it but we just started but im still not sure if that is going to be it.

Because I have logged the car and for some reason at a idle im not getting any fuel trim readings on my mitsulogger logs and no o2 censor feedback trim. So Im thinking i have a faulty o2 censor.

I have done a boost leak test and had no problems with 30 psi. Just to make sure i ordered a vacuum block that will be in this week so i know i wont have any chance of leaks.

So i let the car warm up and just in nuetral I give the car a lil gas but as soon as i each 3500 rpms the car just bogs out. And then if i try and drive it as soon as the car is put under the very first sign of a load it just bogs out like i just blew off a intercooler pipe.

I have recently done the following in detail: Ebay Manifold, BBK 75mm TB, AeroMotive FPR, HKS Fuel Rail, 650cc PTE Injectors, HKS 272 Intake and Exhaust Cams, HKS EVC, HKS Intake, Innovative Wide Band, Fuel Pressure Gauge, AFR Gauge(obviously) ( Cams,EVC, Intake,Injectors and a Dyno Flash tune but i junked it were done by the previous owner bought the car at a dealer new used in the winter of 05 with 18k hasnt been driven in two years to this day going on three now)

With the mods i also had to remove the egr valve and as for right now the ISC is not on but will be as soon as i get my TB out to FFTEC. They will be doing the bushings, the throttle wheel and ISC adapter plate. Not sure if im forgetting anything and its long sorry but im just not having any luck. I would like to have it in decent running order before i take it to be fine dyno tuned.

Thanks Jeremy

 

first things first, get the 02 sensor working. what OBDII codes do you have?

 

The injectors are already rescaled and everything? Those periphery codes prevent CELs as close as I have been able to determine, not so much that they can fix malfunctions like that. If you think you have a bad O2 you could force the car to run in Open loop and see if it runs better.

It sounds like you have a bad one though based on your description though.

 

Well I did successfully manage to turn off my EGR and Rear o2 censor with no problems.

Im not sure how i would go about forcing the car to run in open loop. I havent tested how it runs after disabling the o1 i just checked it on scan tech.

Ill check on it today depending when i get out of work.
