Question

My 2000 i30 has this code starts and drives good, at point example merging to high way the car chocks or hasitate, then slowly builds speed. At morning first start I have to push the gas pedal 15-30 sec for the car to run, thereafter it idles very loud and high. 3000 rpm. I changed the AIC VALVE with used one from junkyard, still same problem. It's own was somewhat better. Any suggestions?

Answer 1

Most of the times when the AAC/AIC valve fails, it will also damage the Engine Control Module (ECM) or if the valve you replace was damage, it could have also damage the ECM. At this point I recommend getting a new valve (you can get a new aftermarket valve for less than $80) and have the ECM rebuilt (Check eBay, you can get the ECM rebuild for about $100).
