Normal Car
Hi guys, just wondering if any of you know whats going on with my normal car. When left idling the engine blips up to 2500 revs then almost dies then
blips and dies, blips and dies, etc. Its also left the car fairly undrivable. The last time this happened it was blamed on a kink in the vacuum tube
for the brake servo, when it was straightened out the car went fine. This time there is no kink in the vacuum tube......... any ideas.

If it is a pinto injection, its sounds like the cold start injector - very common fault.

I have just sweat tears and cried blood arsing around with the vacuum pump(£104) on the back of my Carltons alternator after the aforementioned pump
self destructed.What did I find when dismantling it all? A kinked pipe(£4). I want an Escort Mk2 as my sensible car now.
Sorry not to be of any help at all Fin.
Regards
Ian

Knowing Fin, we're either talking about a Toyota MR2 mk1 or a Fiat Punto, I suspect the Punto!

Hiya,
Have you checked the intake tubing? I had a similar snag with my mazda, the bugger wouldn't idle right and kept hunting between rev's. I
traced the fault to a split in the intake hose, a bit of that stretchy electrical tape later and everything was running sweet.

It Runs!!!!! Bring on the SVA!

What ever you do fin, DO NOT start back probing any of the electronics on it, That action tends to blow the ECU!!!!!!!!!
Sounds like a leaking vaccuum pipe. Fiat ones are notorious for just falling apart with time. check ALL the small vaccuum pipes that connect to the
manifold.
Hope this helps.
Enjoy.

My mk1 MR2 had a similar problem. It has an idle-up valve which lets a tad more air in (and therefore fuel) at idle. After having a bit of a
"fiddle" with it (technical term for taking it off, waggling it about and putting it back), it's been fine. Don't know if
Punto has a similar device??

Fin,
Just thought of a another cause of this on a MR2 (yeah, I know keep talking about the wrong car, but it might apply!)...
Air locks in the coolant system. As the air bubble passes the temp sensor the temp suddenly changes causing the ECU to think that its cold and so
kicks it into idle mode, then when the coolant passes the sensor it realises its already warm so reverts to normal running.
