Hi Guys,
I have a problem with my Ford Fiesta 1999 1.25L.
When I push the clutch in to slow down (at a traffic light, or junction) or go to change gear (but don't) the revs will drop blow 1000 to about 500 for a short period of time (maybe 1 - 1.5 seconds) before returning to their idle speed at approx 1000. When this happens the battery light comes on as if the car is about to stall (it never does though just to point out!), it always returns to its proper idle.
This problem occur at totally random intervals, but is more likely to happen when it has just been started, it is cold, when there is a large load on the battery (When full beams are on, fan heater and window heaters etc). Once the engine has been running for 2-4 miles it doesn't happen as often but still can happen every now and again in the same journey.
I took it to my local garage today for its annual service and I mentioned that it could be the idle speed control valve (I read up on this and it seems that the ISCV was the culprit in many cases), they changed the oil, oil filter and pollen filter (they said the spark plugs and air filter didn't need replacing as they were in good condition) and they also gave the idle speed control valve a good clean out, it was very dirty inside apparently. They took it for a test drive about 4-5 miles and there were no problems with it (Typical!), the moment I drive out of the garage pull up to a junction the car does it's usual 'going to stall but not quite' routine.
Does any one have any suggestions as to what this could be?! I don't have the money to go back and forth to the garage trying new things out as I can see it'll get quite expensive very fast if the problem isn't fixed (A lot like how other people's similar problems have ended up!)
Also, if this problem cannot be fixed, is the car okay to drive? I mean am I doing any damage to the engine if I don't fix this problem?! Any help would be much appreciated, and sorry for the long post, I wanted to make sure I gave a really concise description of my problem!
Thanks :)
