Question about 1999 Suzuki Vitara

Rev counter jumps when idling and then engine cuts out

I have a 1999 Golf 1.6 and it works perfectly except for every now and then the rev counter will start jumping (between 0 and 2) and it then seems to cause the engine to cut out. It usually happens within the first 5 minutes of me driving the car; sometimes I will just be waiting at a junction and then when I go to pull off the car has cut out and the battery light has come on without me even realising.
When driving at speed the rev counter works fine, it is only whilst doing very low speeds or idling that it seems to happen. I suspect it is because the rev counter goes too low that the engine therefore cuts out although I have no idea what would be causing this. As I say, the problem is intermittent and sometimes it will start up and drive fine. Any help would be much appreciated! Thanks

    Thanks for your responses guys.



    I don't think it's to do with the sensor because if it was just sensing it wrong it wouldn't actually cause the engine to cut out would it? (I'm only guessing here - I haven't a clue!?)



    Is there any way of checking whether or not it is the spark plug wire emissionwiz? And if that is the problem, would it be expensive to have fixed?

    at night spray a mist of water on the plug wires and see if you see a spark or the engine misses, I am pretty sure about this diagnosis, have seen it many times in the shop.

IF YOU SEE CHECK ENGINE LIGHT FLASHING LOOK FOR TURBOCHARGER WASTEGATE REGULATOR VALVE FAULT OR MAP SENSOR FAULT.THAT COULD BE YOUR PROBLEM.IF NO CHECK ENGINE LIGHT FLASHING YOU COULD HAVE A RESTRICTED EXHAUST SYSTEM BAD TURBOCHARGER, RESTRICTED FUEL FILTER.ALL THOSE THINGS WILL CAUSE POWER LOST.

Hi, do u know what can be the cause of rev counter going up and down whilst idle? on a golf gti cheers


VWs are not well known to have idle issues however, a bad or stuck Idle Air Control valve, or a bad Mass Air Flow meter can cause this issue.

My toledo v5 has a jumpy idle ive changed maf sensor cleaned throttle body changed engine temp sender still no luck jumps between 600-1200 rpm on idle never stalls thanks for any help


Do you perhaps have a small exhaust leak? Check ahead of the O2 sensor. If the exhaust can **** fresh air in it can't give the computer an accurate reading and the engine will rev up and down at idle. Hope this helps.

The rev counter could be faulty.
I hope the engine is responding ok on accelaration inspite of the rev counter being stuck on 3000rpm , if so thn its definately the rev counter being faulty.

When in neutral or low rev occassionaly cuts out


it's your idle air valve located on the backside of your intake round with two large lines going to it make sure you check junkyards first for one because you'll faint when you hear the price at the parts counter.

Rev counter jumps whilst idling and then engine cuts out


Your problem sounds as if the thermo sensor....which controls the air fuel ratio when engine is cold....is faulty. It is a common fault on this model.
This is not an expensive part, and takes only a short time to fit.
Good luck
