Nope, I gave up on everything else once I found the tb doing that.
Ill try again tomorrow on the ICV. I know the car ran Without a pipe on the ICV though.
Ok, engine started, open throttle, revs stuck at 2k.
Pulled off the brake vac pipe and revs rose. Put back on and it settled back to 2k.
Unplugged ICV and nothing happened?
Next I pulled out the sensor at far end of inlet plenum (not sure what this one is? - it was quite loose!) revs rose, then...
Will do. I'll try later if I get any time.
I'm all for cleaning the throttle body (again), but I find it hard to believe both have exactly the same problem - especially when the second one came from a car that was running perfectly.
Rob, a brand new Renault cable was fitted yesterday and I made the route as smooth as possible, there are no sharp kinks etc. The old one was almost new as well.
I've done all of that with the tb already, but i'll try again tonight. Used a whole can of carb cleaner on it!
Russ, i'll pm you.
I've tried refurbing my original tb and the spring feels really tight, the recoil on the butterfly could snap your finger off so i'm convinced it's not that!
See the original throttle body did that so that was the first thing I replaced. I've not checked if the new one does it because it came straight of a car that was running fine, but I can check.
OK, so start the car and it idles spot on.
Touch the throttle, drive away etc then come to a junction, or anything and the car idles at 2000 rpm (maybe more). Occasionally it settles at 1500rpm and then 'hunts' and will rev between 1500 and 2000. If you then stab the throttle the idle settles...
I do have a spare Lambda that I was going to try at some point. It won't be the gaskets, they were all replaced with genuine items when the engine was rebuilt over the winter.
Thanks mate. I've tried two maf sensors and that's not changed the way it behaves, so cable and idle valve next I think. Process of elimination I guess.
With the original throttle body on I could do that! Would that indicate the cable?
Just to confirm when you come off the throttle it can do three things:
Idle fine
The idle will 'hunt' between 1000 and 1400 rpm
The idle will hold at 2000rpm (this is what it does the majority of the time)
Cheers
I hope it's that mate. As if you don't look enough of a prick already driving a red bumpered Clio with a Martini stripe down the middle of it through the middle of a city centre, for it only to sit there and rev itself to death. This is why it's only done 8 miles in 3 months. LOL.
I've bought a...
It's my Jedi powers!
I settles to an idle fine about 10% of the time. The rest of the time it either hunts between 1000 and 1400rpm and the majority of the time it just idles at 2000 rpm. If you then blip the throttle it settles down fine. Does it all the time!
I've changed the throttle body...
Progress!
So the other day I rolled the car out of the garage in preparation to fit the Leda coilovers.
Shortly afterwards it all got a bit mental up here and started to rain a bit:
It was quite a bit worse in Newcastle, but it was virtually about to flood the garage. An empty plant...
