Stupid Misfiring, Venom Injectors, AFM codes?

[spainobain1234]

:: angry ::
I am driving and the car stops accelerating just before it hits 1PSI of boost.

Runs rich, wont exceed 3500rpm, backfires, cuts fuel without CEL blinking.
Boost no longer runs because the engine will not exceed 3500 RPMS
Is this fuel Cut, Is the ECU freaking out? recognizing something with the Injectors or something?!

34: Some other AFM shit

So basically, I want someone to look at my car, it idles! But it sure ain't running. I cannot figure this one out.

Lexus AFM should be working as i plugged in my electrical unit from the stock 7mgte AFM into the lexus afm housing.

Car was running fine for 20 minutes. I shut her down, turned her back on and she died. took her for a drive, she wont go above 3500rpm.

02 sensor plugged in. Could it be simple as spark plugs?

Ahh, the aroma of Tacoma...

Fix the 31. Not only is it serious but it's only one code.

 

[spainobain1234]

It is misfiring around 3500 RPMs only when driving, when idling and revving, the engine carries through but blows black smoke like one other... No boost leaks. This makes no sense.

I wired an safc, and cut the wire KS in the ecu. The car ran like crap before I began wiring. I really need a Toyota mechanic to check it out.

The codes are 24 31 34.

Does it matter the order of which wiring harness clips attach to the 550cc fuel injectors? The computer throws a new code every day I start it. I cant tell what is resulting from?

UGH I need help...

Sigh. Sucked in yet again...

Yes, it matters. Just like it matters which spark plug wires you attach

Wait, the car ran like crap BEFORE you started wiring extra stuff in?

How much for your gt35 when you blow the engine?

Okay, so the sensor in my Lexus afm is bad. But so is my stock 7mgte AFm sensor. So which AFM sensor do I want, a new Lexus Sensor? Or the Stock Sensor?

Does anybody wanna sell me a sensor for the Lexus AFM?

The electronics are the same, only the housing is different. How do you know its not the wiring?

When you have 34, fuel injection was halted, and the MIL did in fact illuminate while it was halted. Just so you know.

Okay so to me... the stupid owner, my car runs great. It was the venom injectors, the 02 sensor from the stock 25 year old ct26 blowing oil through the downpipe, and also wastegate stuck shut when at first it was stuck open. the atmosphere blow off valve plumbed back into the intake helps. gotta love at home mechanics.

Anyway, this forum sucks balls

But none of us are STUPID enough to use Venom Injectors....

I know what you mean, sometimes you don't need to be shit on when your already stressed from a nonrunning car. maybe some people around here can lighten up a bit when people ask for help. not everyone has been working on cars for 20 years/proper training etc.

regarding the venom injectors, it's not a widely known problem from what I gather, unless you happen to see the sticky on one of the forums.

Lighten up, Francis!
