Tharindu Senadeera Posted August 12, 2023 Share Posted August 12, 2023 (edited) Hi Folks, My car is Toyota Corolla AE100. When A / C turns on engine is idling up normally but it cannot hold the RPM, just after idle up RPM again drops. When in traffic it is a big issue because RPM getting low and low. I have changed an ECU but it shows the same issue. Checked all the sensors related to throttle body area. Checked the A/C compressor also. Then mechanic said that the last thing that can be done is ECU remapping. Are there any other thing to check? Need your idea Thanks Edited August 12, 2023 by Tharindu Senadeera Quote Link to comment Share on other sites More sharing options...
