It passed smog this morning. It still has some issue affecting closed loop operation that maybe you can help me with. Here's what we did to make it pass. Run at 2500 rpm for a few minutes until the engine sound changed. Ie went into closed loop. Then as fast as we could, run the test because the closed loop at idle was correct readings for about 45 seconds. Then after, the idle HC's went high like 500 and CO like 2.10.
Here's what I hope you can help me with: learning how to identify closed loop operation and to ultimately solve open loop from happening at idle. Thanks for your help. Pete
