Consult + Afm (Local Help!)

[agentx]

Hey guys - just wondering if someone in the south east has the consult cable / program to check error codes and an r32 / rb20 AFM so i can check if mine is effed

6 pack of your favourite beer for your troubles

p.s. I'm in Box Hill so somewhere close by would be awesome!

No one drinks beer here?

you can probably debug it without consult

if AFM is stuffed rev is capped at 2500rpm

the engine check light should also stay on

[agentx]

its revving over 2500 fine, and did an ecu diagnostic and got 55 - all good there too. Is it still worth replacing the AFM or is the AFM like an ON/OFF thing (works or doesnt)?

Thanks mate

[paulr33]

the afm usually works or doesnt

what is the problem you are trying to solve

not

what is the problem you think you have?

[agentx]

I "think" its starving for fuel ... but then how does it pull really hard on high RPM's

The problem is listed in the link above...

think we are having a similar problem........... mine will run fine, then after a while of driving at normal temp it will hunt while idling stall as i stop, hesitate when i press the throttle....... skylines eh!? like i said mate ill have my consult cable and ecutalk or similar installed by tom arvo, if you wanna head down sunday or something maybe we can help each other out! 2 heads are better than one i say!

[paulr33]

there are some things that make no sense in that thread

if the cat temp light is on or engine check light then why does ecu diag return no error? are you sure your doing it correctly?

fuel problems dont develop themselves and the main engine basically follows what the throttle and sensors do

ie the engine operates and the sensors tell the ECU how much fuel to use etc

not the other way around.

a f**ked TPS could explain some of the issues you have

as could a dirty afm so maybe consult is the best way

might be easier to just buy a consult cable - arent they like $50 ?

also what magically changed a week ago?

what else has been done to the car before this "week ago"

have you tried a simple ECU reset?

[agentx]

Hi Paul - I've cleaned the AFM thoroughly - reset the ECU as well. The EGT light NOW doesn't turn on since I took the ecu out for a diagnostic and found out the constant led on it wasn't on (made sure it was on when the ignition was on by turning the screw before i put it back in after the diagnostic and that has gotten rid of the EGT light.

So if the diagnostic doesn't return any codes, still worthwhile doing a consult check? Nothing was touched on the car in the build up to this, just started happening all of a sudden! The fuel pump change was done over a month before this.

Plattsy, Im going away for the weekend this week sorry let me know how you go with it all and we might catch up next week if you're free ... might swap TPS's and AFM's and see if it changes anything - although if both of ours are screwed up, it wont help

[paulr33]

who installed the fuel pump

did you refit everything exactly

is it fully slid back into the bottom of the tank using the slide on the top ceiling of the tank?

what pump has been fitted

[agentx]

Bosch 040 I think, dr drift (Sam) fit it so I'm pretty sure he would've done it right? Also if it wasn't fit properly, wouldnt i get the issues straight away instead of after a month plus?

thanks for your help so far

when my afm was stuffed it would go into what felt like rich and retard( like hitting a wall etc ) at high rpm, then it only went in limp mode after a hard thrash. so not really broken or not mine was in the between

hmmm interesting - i'll swap with a known good one soon and see - thanks mate

[agentx]

FYI guys - in case it helps anyone later on, it turned out to be a hose on the fuel pump - wasn't tightened up properly.
