Starting problems until warm!
« on: 26 January 2005, 16:09 »
Hi all, I'll try and explain exactly what is going on with my car then hopefully someone can have an idea :) I think all these points are related somehow!

Problem 1 - From cold - Turn key and engine fires, but is very jeky and then cuts out. If i start it in the same way but hit the accelerator to help things along it fires up fine

Problem 2 - Once fired up she revs at around 950 rpm, the revs used to increse for a short while before, but now they don't, but if i slightly press the accelerator to increase the revs to around 1000 rpm and hold it there the rev counter moves up to 1100 and back down to 1000 all the time (like a heart beat) is this right?

Problem 3 - When driving from cold and i stop or dip the clutch the revs drop to around 750 and then climb back up to 950, this happens untill the engine is fully warmed then this disapears?

Hope someone can help!

Try removing your ISV and giving it a good clean.

Also if ya have trouble firing up, then try unplugging the cold start valve.
It is on the end of the inlet manifold, its like a 5th injector.

Ok, cleaned it all out and the pipes coming from it, put it all back and it's now idleing at around 450rpm, so i am taking this as a good thing and i am going to reset the idel and hopefully it will be ok :)
