i have basically no knowledge about cars, my friend who is a mechanic got it idling a bit better, i bought the car as it is now, the engine isnt completely stock, turbo cam, race series valve springs, ported head, bigger exaust valves etc... i havent had a tune up on it yet as i have only had it for a little while and have only had my licence for around a month, plus im still at school so the money doesnt flow into my pocket very well... basically i would like a simple explaination of why it could be doing this and a way to fix it put in simple terms..
cheers
