anti lag idle

[bluemaumau]

oh ok it seems the gze has decided to go fully anti lag on me now, before it was just hunting, then it fixed itself.

now after doing everything i can think of

it idles at 2000rpm and when it reaches operating temp, it starts with this anti lag thing. it actually runs then sounds like it cuts then goes again. (closet thing to anti-lag that isnt )

sometimes itll do it for 30 seconds then return to idle (2000rpm), then go again soon.

(anti lag = 2200rpm to 1400rpm.)

needing help.......

tried different coil packs?

[bluemaumau]

nope. can that cause bad idle?

is there a way of testing them?

Do you have air in the cooling system?

[bluemaumau]

ive tried as much as possible to get it out, maybe i gotta get a new thermostat.

on the cold start, does it matter if the lines are mixed up? (water lines to it)

i just checked my leads with the multimeter on 20k

lead 1 - 6.8
lead 2 - 6.8
lead 3 - 4.9
lead 4 - 1

ill grab some more leads tomorrow

they look about right. Normal supression core is 10k ohms per metre.

The hunting is caused by the fact that the ECU is designed to save fuel on overrun so whenever the TPS switch is closed and the engine speed is above 200, it turns off the injectors.

That causes the bad surging/anti lag sounds.

If it idles that high then there is air getting past the throttle somewhere.
It has an air leak or the throttle plate is held open.

There is nothing else that will fix it unless you stop the air leak.

ok ill pull the inlet off again. and torque up.

are you sure about teh leads. no 4 has no continuity

That would cause a miss, not a high idle..



Find a fitting into the inlet manifold and put compressed in into the manifold and see if you can find where it hisses out.

good idea. cheers matt

i've got some good leads, if you wanna make me an offer as i need to change them cause i got evo coil packs now

you said no 4 had 1, so that'd make it 1k ohm.
The others were 6ish or something.
