And some pics of the car itself? Sounds like one hell of a ride!!

Haha Gloverman that's gold!!! but i agree.....

everybody stay calm.... it was just a lead that had sh!t itself :D

so just wondering if a incorectly set tps can cause it to drop a cylinder? when its cold it runs fine its when it gets up to temp thats when the issue starts... at idle there is a miss and then when driving gently its on 7.... have all the plugs out and none of them look any different... im...

Just incase anyone else has this issue... worked well setting it with the multi meter out of the vehicle...

okay... so i got a new tps :) the issue i have is that i cant adjust it in the vehicle when its running.... so i used the steps in here http://www.lexls.com/tutorials/EFI/tps.html with the multi meter... but i cant get it perfect as per instructions... if i just get it with no resistance then...

sounds like tps... let us know when you try a different one...

thanks samsdad :D i was messing around with radiator hoses and my thermo switch housing over the weekend could i have knocked/upset something on the front of the motor that would also throw a 41 code?

oh its a converted vehicle with the wiring done by gloverman about 18 months ago and has run fine till today i think the motor is around a 94 and had log headers when i got it... cheers

hey guys, so today my 1uz started doing this strange lurching thing, it kind of cuts the entire ignition for a split second then carries on as if it didnt happen... over the course of the day this got worse... i was actually loosing drive from my gear box, like i would manual shift up the gears...

sounds like the same issue i had on my hiace conversion... mine was that i had piped part of the intake wrong... have you got the pipe from the IACV (about a inch wide pipe coming out in front of the inlet manifold) conected between the air flow meter and the throttle body??? i just wonder cos i...

will it stay running if you keep the throttle open?

nice!!! it sucks when its so simple yet takes so long to find.... had a similar issue with my conversion last weekend... went over and over all the hard stuff and turned out to be the simplest thing.....

yeah... turned out to be the throttle body... main return spring had lost tension so shortend up the spring and she's all sorted....

and it was...... lol awesome news though :D

just another thing to look at... if the idle air control valve is plumbed incorrectly it will give you a afm fault code and the motor will fire for a few moments then die.. also running it in a super rich state (fouling plugs) etc it has to be plumbed after the afm and before the butterfly...

two of the coolest things ever coming together :D very cool project my man...

^^^^ yip what samsdad said :)

have you got the pipe from the idle stepper motor (in front of the intake manifold) piped in after the air flow meter? i thought i could just use a little air filter on it but it has to draw air past the afm at idle...

your motor looks insane man!!!! looks like you just popped down to toyota and picked up a brand new one!!! love ya work so far....
