It doesnt have a tacho so i'm not sure but it seems to idle normally it just coughs and vibrates and wants to stall frequently. I took it to hyundai dealership about 4 weeks ago and they hooked it up to their computer and adjusted the idle and checked leads, plugs, fuel injectors etc but couldnt find anything wrong with it. Then a week after I took it to a different mechanics and got a major service and new fuel filter and new air filter and they checked the idle and everything and they said it was a dirty throttle body so they cleaned it out and it was okay for a day or so then it started happening again. I then took it to a third mechanic who went over everything and hooked it up to their computer but go no codes, they said it was the throttle body and that the previous mechanic hadnt cleaned arount to rim of the butterfly, they cleaned it and told me to drive 80km in distance to reset the computer. I done that but problem was happening still. It also has had the timing belt replaced about 2000km's ago and today I cleaned out the IAC valve. So it idles fine when I start the car up then a few minutes into the drive as soon as I pull up somewhere the problem starts happening.
