Hi guys, my car idles fine until warmed up, but when fully warmed up it idles fast slow fast slow, and often stalls... Also, the stock boost gauge doesnt work, just twitches when I floor it, so i took the pipe off the sensor thingy, and blew some air down the pipe and the gauge shoots up, so it's working ok... The gauge works off pressure, but suction coming from the balance bar where it connects... ? Maybe there is no boost?

 

I also stuck an airline on the balance bar in short bursts, to see if i could hear any leaks, and sounds like one turbo is spinning up, but not the other, strange? It runs fine when not on idle, so cant be a turbo issue, can it? They are newly recond, could it be something else? A sloenoid perhaps?

 

I've also relocated the dett sensor with a new one, and still keep getting a random 34, but i'm confident it isn't detting, don't know what to do!!!

 

Sorry for all the questions in one thread peeps :-)

 

Any helps much appreciated guys.........

these idle problems are a pain in the arse as they can be one in a million things or even more.

The idle problem when warm says to me its related to either the 'Air regulator' or 'Idle air control valve' both connected to each other at the back of the engine near the battery.

The air regulator acts as a automatic choke so may be your best place to start.

Cheers mate, I'll have a look and clean em up, are they a pain in the buttocks to remove? :-)

Ask John300zx for help with this bit, i couldn't get mine off because the pipe was rock hard and then ran into other troubles

Maybe your car needs a little tune up, if i was you id take it to a zed specialist it will save you alot of time.

I would if i could mate, but can't get it MOT'd till I sort out these little but very niggling problems, arrrrgh :-)
