Idling problem

[pole drift]

my car had exacly the same symptoms,turned out my ecu was sending funny signals to my fuel pump,cutting it off for a second and not signaling it properly so the car would rev smooth,i had this problem for a while,wired the fuel pump direct and its be fine ever since...i dunno is your pump wired direct or what...

yup the pump is wired direct to the battery via switch.

Danmoorhead reckons i could have a vaccum pipe disconnected.

Another thing is that the car hasnt ran in a while, would that contribute to it??

No haveing it sat for a while shouldnt cause that,was it running fine the last time you started it?what work have you done to it since...it does sound like a vacum pipe,air in the system or maybe a airflow meter issue....?if it was running fine before and you havent been working on it,then obviosuly there cant be vacum pipe disconnected,could be a split pipe,is the cooling system bleed?

Bleed the cooling system, its prob the handiest to do at the moment without another AFM.
Is there water running through the top right hose going from the rad to the block. Giv it a squeeze... if theres nothing running through and you have coolant u'll need to get the thermostat to open and let everything thru. Jump in the car and flick on the fans with a bit of heat, also pop off the radiator cap (careful shes not silly hot, burn urself) and have a look at the level in the rad.

Have you checked the idle control valve? I had the exact same problem on my rx idling between 1k AND 1.5k so i brought into eddie doyle and he told me to adjust the idle control valve, located on the throttle body elbow on my rx7. twist the screw in all the way and then screw out 1 & 1/2 turns and then check, if problem persists, screw out another 1/4 to a 1/2 turn....

This worked for me!!!!

From what i can hear,the car seems lumpy through the rev's...the idles control valve will only effect ideal and shouldnt affect performance through the rev range!

Is the car not idling on its own with no throttle at all from 1.5K to 2K and back to 1.5K etc, etc...Thats what it sounds like anyway! Adjusting this idle control valve will set the idle back steady and it will stop hunting on its own, well should do anyway, correct me if im wrong but this was my experience and it worked for me. That was 2 days ago and it hasnt happened since....maybe i got lucky
