Bought my car beginning of this year, It's a 1997 1.0 VW lupo. It's done approximately 32,000 miles and pretty much brand new internally and externally for its age
So, 2 months ago i stalled it at lights, upon getting the engine back on the revs were creeping up really high on their own without pushing the gas pedal. It stayed this way through gear changes, to the point where i had to pull over and turn the engine off for a short while. Put it back on and the same thing occured while stationary, until it settled down and went normal - but the engine light came on!
I got a local mechanic to look at it, he did the super duper machine analyser thing (sorry i'm absolutely useless at this stuff) and he said there's nothing wrong with it mechanically - him, and my parents basically were looking at me like im stupid. He reset the light on the dash.
It was driving normally for a while - then the engine light came on the dash again. Now, recently its started the process again - only more frequently now. Sometimes even at the first ignition of the day.
Its like the car has an attitude and starts revving up 2000-3000 before settling normally. Or, if its being extra, it will not start at all, and i have to push the gas pedal and maintain revs over 1000 until it settles normally.
One thing i've noticed too, the coolant level is falling rapidly - the light came on, i filled it with the matching colour (pink) up to the max level - one month later it is below the minimum level.
Oh and i can smell something when i put on my A/C
So to summarise:
Occasional ignition failure - have to use gas to get it going
rapid coolant leak - maximum to below minimum in a month
high revs without pushing pedal - sometimes random, but mostly at ignition.
Smelly A/C - cant describe the smell - can only liken it to a weakened petrol smell?
any ideas will be great, because im not taking it to a mechanic again to be told there's nothing wrong with it again!!
