Hi folks my little 1.0 gls w reg is really struggling to start when cold, the engine starts first time but bounces around and seems to drop revs until it stalls.
If i start the car with my foot on accelerator it starts fine and and will idle just above 1000rpm once accelerator has been held for a few minutes.
Also if idling if i turn on a few things like lights etc the idle speed dips to almost stalling the car also occasionally hesitates while going slow in a higher gear.
Any ideas of the first thing to check???

Is eml on, i'd try get a reader on it and see what it comes up with, ive had similar prob with idle air control valve (hesitation and poor starting) but could be a number of things. good luck.

Sorry should have said no eml on problem really only bad when engine cold.

i've just had a simlar problem, you had new spark plugs recently?
if nt get sum try that, if not them try the leads, sound like its struggling for a spark, and its missing 1
hope this helps

Gonna try new plugs tommorrow took the idle control valve off for a clean which i thought you couldent do on the 1.0 12v but you can? This didnt help just dont want to have to blindly replace sensors like other forums have said!

did you try the plugs?

Yeah mate new plugs didnt help had a muck around with the idle controller and now im gettin engine light comin on so gonna put it in to garage next week to get it changed and ecu reset.

I had this with my 1.2 16v, Get the air mass sensor changed. You can pick them up for around £30 on ebay (maybe cheaper) and it should sort the problem out fine.

i had all of the problems you listed until one day it used to ignite the engine then stall straight away!!!! Real pain to drive to a garage as had to keep the accelerator pedal pressed down to keep revs up and prevent instant stall!!!!

Changes this part and it should sort it??

Hope this helps.
