This is allegedly a common fault, I can't make the car do it which is never helpfull when trying to get a car sorted, It is a tempromental fault,
I am in desperate need of some help as I have been ****ed in the ass by Vauxhalls so many times I dont want to just take it there with a blank cheque again!
I'll write out the problem, to scan read just pick out the bold bits!
For well over a year, on occasions If I drove for a period, then stopped the car, then re started not long after, e.g at petrol station, of posting a letter, when restarting the engine it would take a few seconds of turning over to actually start, once it started was fine. I dont know if thats related to my current problem or not. It only did this less often than one in 15.
so day 1, i was coming upto a roundabout, there was a car infront of me, so i was stop start getting to the round about, guy infront went, then why my gap came round, i went to drive off, and it felt like i had no power i looked down it handnt stalled, i put the clutch down a revved it a bit, then it was ok and i pulled away, bit like if you tried to pull away in fifth but without the resistance, just no power. i thought nothing of this.
few days later, sitting in stop start traffic one morning, and after a hundred yards of stop start the car revs just dropped away silent as a mouse! and it stalled, it restarted ok, then got a bit of a drive 100 yards, got to a roundabout, braked, put clutch down, car revs dropped and it stalled.
and it does this at junctions of traffic at unpredictable times
car seems to run a bit lumpy and jerky, and when when you floor it on a run in one gear e.g 3rd it seems to have a few bursts of power rather than a constant stream, not sure if this is related either,
I had a K&N panel on there but i'll put the paper one in, just to take out a variable!
so step one, the common solution, take off the air intake pipe and clean out the throttle body with carb cleaner/ brake cleaner / petrol as per how to on here. it was pretty dirty so i felt confident
so i took off what haynes call the 'idle control speed stepper motor' (also known as the 'air intake control valve' or 'idle control valve'), gave that a damn good going over too
redeXed the petrol and cleaned the spark plugs a bit
so so many posts on here link stalling to the EGR, i hear I can blank of the EGR with a blanking gasket, at least this would tell me if its that or not
failing that, if the idle control valve is knackered a new one and gaskets looking like under £70 from , so thats next,
but what i dont get is if you assume it stalls cos the idle control valve is faulty, surely its faulty as in it remains shut, so the engine has no air? if it was that surely it would cough and judder rather than silently stall ?
when i rang my local vauxhall garage and asked about a recal on EGR valves, they said there wasnt one, they said they do some work for around £100, actual price still not confirmed, where they clean the throttle body (i've done that) clean out the EGR (eh) and change the oil seperator (what the hell?)
So please can some people who know what they are talking about, or people who have had this please help,
also please can someone arrow my EGR valve on a picture so i can get it off
Many thanks in advance
