I purchased an 01 CRV EX 5spd last month. It has approximately 138k on it at the moment. I've adjusted the valves, checked my spark plugs & wires. Recently my ck engine light came on while my idle kept surging between 1000 & 1200 RPM. My mechanic said he cleaned the IACV and adjusted my idle before I had the valves adjusted. After the valves were adjusted I had this idling problem. I have followed the steps to troubleshooting the issues. I disconnected the IACV while the engine was running, and my idle dropped down to 750 RPM. Once I plugged the connector back in on the IACV, the idle started jumping around. I took the IACV off, and the screen was clean as a whistle. I put the IACV back on, and sprayed the TB cleaner and did not notice any changes in the RPM's. I went through and performed the idle relearn process, and also checked my coolant levels which appear to be ok. Does anyone have any suggestions. Any help would be greatly appreciated. I don't want to spend $200 on an IACV if that truly isn't the issue.
