2.0l 16v idle problem

[Andy-H 0]

Sure does, really smoother drive in it now :D Did the same thing to me old Golf and that had the same kind of effect.

 

Yeah, must check the fluid levels again actually, recently drained the system as it was full of really old fluid which looked as though it had been boiled and also found quite a bit of water in it as well :shock: not re-checked it since bleeding and running for a while although the light was flickering before I drained the system :( I did give the switch on the handbrake a bit of a service with some electrical cleaner and it did stop it for a while but just started up again.

 

Really, I think I need a new master cylinder as Horney suggested as well but I'll have to wait for some more pennies :lol:

Even if it doesn't sort the problem completely, I think it's a worth while task anyway that will give you a difference in the way the car performs :)

Cleaned mine today, was rather dirty one side but clean the other.

 

Had a bit of trouble undoing the 4 bolts they did start to round off but a few light taps with a hammer on the alan key sorted that out :D

 

Gave it a good old clean and put it all back on then went for a spin

 

It hasnt curred the problem but the car feels more urgent when i put my foot down, also when the revs do decide to drop down when i engage the cluth it happens alot quicker.

 

The how to guide was very helpfull, so much easyer when you have pics to help you out. Especialy when you know hardly anything about the engine bay :D

 

Have a few pics I will upload later when i get the time

 

:salute:

Here are the pics as promised

 

to start with

 

the inside of the manifold

 

and after a good clean

 

 

also my little helper hard at work

[Swompy 0]

Cleaning my thottle body seams to have half sorted the probolem.

 

In the mornings when I leave for work ( 5.30 am) it starts no probolem what so ever, may rev a little high but no probolem in starting.

 

Now when i leave work to come home or when the engine is cold but warm (like when the engine has been running but not for a couple of hours) it struggels to start properly. It will start but the revs will be very low and the engine will realy ruff. Almost as if you could hear each cylinder going off one at a time, it will pick its self up after a few seconds. Then it may run fine or it will rev high ( around 2K )

 

I've all ready cleaned the ISV

 

Any one got any ideas as to what could be causing it :shrug: :confused4:

ive been looking at mine today, im thinking it maybe to 1. your throttle cable or 2.the switch on the throttle?......thats me guessing

[nmahi 0]

p.s them throttle bodies as nasty,you should be ashamed at yourself... :salute:

[Swompy 0]

HAHA no worrys, I dont think it is the switch or cable as Dave and Graham both looked at that when I payed the a visit a few weeks ago and they said they are good.

 

Only thing I can think of is either the cold start valve has a intamitent problem, or its the cold start sensor thingy :confused4:

 

I know I couldnt belive how dirty it was and the car has only covered 85K miles.

 

I'm not to fused about the inlet manifold as I have a nice new and clean one to go on soon 8)

could be cold start valve......i know my brothers 16v mk1 (corrado 9A engine) had problem internally in the cold start valve and John at stealth racing used two old ones to built 1 good one...

so how much would a new valve cost from the steelers? and how easy are they to change
