Question for you guys, I removed the brass restrictor jet from the bypass valve on my 3.4l supercharger about 4 days ago and today I got a P0136 bank 1 sensor 2 code (downstream O2 sensor). Could this be from having taken out the restrictor jet? I read that it could cause rich issues and am thinking I should put it back in. I took it out because it had gotten sucked into the vacuum line.

 

anybody want some very lightly used 668 injectors with harnesses? about 1750 miles on them. $320, and I will get all new toyota o-rings for the top and bottom of the injector.

 

Nah man, that's a bad wiring or bad O2 sensor code. And it's downstream so unless your cats are toast it has a pretty light duty job. Just worn out I'd think

 

What about for f/i? Bought the truck with all mods. Runs a little leen according to my a/f guage. Went to clean the TB and found out its a 76mm. I picked up a stock 65mm tb and while it helped my numbers come down on the guage im experiencing other issues like a bank 2 sensor 1 02 code (2241). Also received some hesitation in and out during spirited acceleration. And I'm not sure on this but I think I'm hearing a slight spark knock (real quiet) right at 2k rpms. Anyway I'm changing out the plugs, gonna try ngk and I'm debating on putting the 76mm back in. It's got mk3 stg1 pulley and program but stg2 exhaust. Should I try and turn this screw? One turn, 1/2 a turn?

 

Crap my cats better not be toast, I had a P0420 last year from a bad cat and replaced both about 6 months ago. I'll start with the sensor thanks!

 

Yeah don't read into it too much. The code literally means the O2 is reporting outside normal parameters. You'd get a 420 if you had a bad cat, this code is for a sensor malfunction.

 

I might be interested. What are u running now? Why u change?

 

just the trd 455's. since I removed the ucon, I don't have the ability to run these. Additionally I wont be waiting for ovtune to make it work either

 

Just took the truck out for it’s first run. 2.6 pulley. With fpr mod. Hit 11 psi. Afr was 11.6 and dropped to 11.0 at redline. Fuel pressure was 38 psi at idle. And 55 psi at redline. What does everyone think?
I gotta grab the tech stream and see what the duty cycle on the injectors are.

 

If they are the 455s then they are probably maxed out.

 

I am tempted to pick those off your hands, then I just need a smaller pulley and maybe ovtune has a dyno day open soon. Hmmm

 

Get er done

 

@GT7 i got. 2.7 quick change pulley. I no u were looking for a 2.8.

 

Yeah that would work, for a slight discount on the injectors

 

Pm me a price and let’s talk lol

 

Was there a gasket or silicone on the 76mm TB, when you removed it from the adapter? If not, that is why it was lean.

Silicone it up, then do the turns like they have shown.

 

Did you disconnect the battery to reset the ecu when changing throttle bodies?

 

They also have the supercharger listed.

I bet they are old, not stocked. If you get it I will order lol.
