I have a 1997 Kia Sportage which idles rough and will not rev up. Have had a scan test/check done which showed the cam position/phase sensor was faulty. Ordered a new sensor which finally arrived after 4 weeks, fitted sensor, cleared ECU codes and started engine only to find it runs exactly the same and logs the same fault code. Have fitted another ECU with still the same fault code logging. The TPS and AFM both seem to be working correctly and log codes if the plugg is removed from them while the engine is running. I NEED SOME HELP WITH WHAT TO DO NEXT. Has anyone any had this fault or a similar problem? Hope to hear from someone with an answer soon. Cheers, frustrated Sportage owner.
