Dodgy idling after remap

[Matt Glanza]

I ajusted it originally but then re set once I found the vacum leak.I will check that sensor later on to see if it does read on off. the butterfly valve closes properly but sounds like the car is being held at 2k by the pedal did try the idle screw again but made no difference

hmmm. sounds like it could be worth checking the tps and setting it up correctly. could be to do with the new throttle pulley, is that holding it open due to it not being adjusted on the cable properly?

 

[Matt Glanza]

The pulley doesn't appear to be holding it open was idling fine when I first started driving the car.fix on then another problem appears

 

[Chris@CCM]

i have a tuning developments throttle pulley, no problems from me???

when you say it was loose? how do you mean? the cable had some slack before it would move the pulley or the pulley itself was loose?

It's ment to shut all the way lol

 

[Matt Glanza]

Just had a look at the function checks.When the engine is off but ignition is on then the black dot is on the idle one then press the acellerator and it goes off but when you turn the car on it goes over to the FPC one and stays there?is there a sign of a problem?

 

[dac69er]

you mean that when the car is running the indicator doesnt change? if so then sounds like either your throttle cable is too tight and its holding the throttle open when the engine is running, or the tps needs adjusting

 

[Matt Glanza]

yea it stays on the FPC one doesnrt go back to the idle

 

[Matt Glanza]

Can anybody else shed so light on my idle problem

You need to check the tps setting, search in the awfully helpful technical section.

right i seem to be going around in circles.i have a new throttle body and tps sensor that i have calibrated and the pfc now shows its on idle with the engine on and the idle goes off when i blip the throttle.the bloody problem is its now hunting again its doing my twat in cos i solved this problem and now sumthing else is causing it?any ideas.thanks

disable the tps on your power fc that will sort it

 

[Matt Glanza]

how do you do that?you can turn the idle control valve off?didnt think the tps could be shut off

yes it can not sure but ive seen it been done

 

[Matt Glanza]

ok hopefully chris mite be able to answer the question later i hope

 

[Matt Glanza]

bump any ideas?also if i unplug the tps sensor it goes to a high idle and doesnt hunt.could my sensor still not be set up right even though i went to the guide on here?thanks

 

[Matt Glanza]

bump can any body help its driving me mad im so close to breaking her

If you remove the plug from the tps and link the bottom 2 connections of the plug with a bit of wire, that is the condition the ecu needs to see for idle control. The tps is closed when the throttle is closed so when you blip the throttle the tps opens, thats why the fc loses the light, but it should come back again if the tps is working correctly.

Is the O2 feedback switched on? If it is, try switching it off.

good input

 

[Matt Glanza]

solved the problem it wasnt calibrated properly.had a dodgy multi meter.and the o2 sensor is still on as the mapper for some reason tuned the car with it on but will be going back up on thursday for a remap.thanks for all your help guys
