why do all your posts read like spam emails?

English is his second language. Or perhaps third.
I wish I could help. I've got nothing. |
I'm assuming the TDR box failed and it's no longer adding fuel and it's going majorly lean.
or this botched injector install that involved the idle valve for some reason is a culprit: idle valve is recirculated via a check valve to prevent leaks... ...i found out that the seal of the idle valvle on the intake manifold wasn t good (my mistske it was during the change of the injectors) i also find out that the silicone hose of the integrated wastegate was damaged. still trying to figure out what an idle valve was removed from the TB to install injectors. Pictures of this idle valve, and the rest of the engine bay please. Does this car have aftermarket FPR? Dear Europeans: The universal law of cause and effect states that for every effect there is a definite cause, likewise for every cause, there is a definite effect. cause: change of the injectors. effect: the other big problem is that my afr at idle is at 14.7 (like before) for a few second and then it slowly decrease to 10-11 |

Dear Europeans: The universal law of cause and effect states that for every effect there is a definite cause, likewise for every cause, there is a definite effect. what injectors did you install? and why? I have smalls red rx7 injectors (was iddling perfectly for 5'000miles and many others use it with vodoo box or tdr without problems). I dont have a fpr (new fuel filter only) but again (tell me if i m wrong) if my problems where linked to the lack of a fpr i'll have suffer from it for long ago... hopefully i'm not european! But i ll tell them! |
So I changed my plug wires, wires, checked for vacuum leaks, checked maf, checked turbo on both side, checked cat (removed totally).
Please tell me if my last suspects are worst to change: - egr valve (could lead to rough idle but with lean condition in my understandment) - ignition coils - ect sensor (what about this??) -idle valve stick closed(a bad one could cause rich idle, but could it explain the blockage in rpm?l I'll love to have your other idea too...i m totally lost. |
maybe check your rear tires. or your headlights.

your ECU + TDR combo is not equipped to handle the 460xx injectors. you're basically flooding the motor to where it can not longer combust under load or stay stoich at idle.

thanks |
To add my new tests:
- when i disconnect the idlle valve (iscv) connector, the iddle still start at 14.7 and then go down rich (no changes) -if i create a vacuum leak post throttle body the idl get back to 14.7 and is then perfection (maybe it could help for diagnogstic) |
Is your idle valve stuck or does it move freely?
|
does your TDR device thing have a vacuum line going to it? is the vacuum line on the FPR still connected/good?
your AFR mixture is obviously off. Both tests above increase the amount of air in the mixture. However, both should also significantly raise the idle speed. |

disconnect the vacuum line on your FPR -- check if there's fuel in it.
