Afm 4agze Issues

[z|gen]

Hey guys..

finally got my car a warrant..

 

but, its still having issues..

 

engine is a 4agze from ae92 with AFM, and has CAS and coil packs..

 

problem is the car dies at low rpm when warm, when engine is cold, its fine, and it runs fine over 3000rpm, but anything under and it sucks..

 

i took it to my mechanic (midas porirua) and they spent 3 days going over it and couldnt find anything and said that its likely to need an aftermarket ecu and an auto sparky..

 

before i go down that route, has anybody got any ideas?

 

was thinking of changing to distributor and single coil set up?

Check it for air leaks, had an AW11 doing a similar thing which turned out to be a hole in the boost pipe.

hey dude,

 

i know my boost guage is buggered on the front - missing the glass, could that possibly be causing problems?

Nah the pressure operates an arm in the rear of it, It does not take boost away from the motor.

ahh k, il take a look at that, i think the pipe between the afm and the t/b is buggered too, is wrapped up in duct tape..

Air leaks and air flow meters don't go well together.

sweet as, il try fix those couple things and see if that helps

still got issues..

 

anyone got ideas on this?

 

hey guys.. me again..

still havent got it sorted, but i think i may have another issue which may be causing it..

 

while having a look at all the vacuum hoses.. for replacing the boost guage and to do the abv mod, mine seems different..

 

iv drawn a rough picture of how mine is setup at the moment, any ideas on correcting it?

 

 

the car is right hand drive if that makes any difference

 

thanks Dave
