My Accord runs perfect at startup, as soon as temp gauge reaches operating temp it hunts at idle and misses slightly at start of acceleration from a stop. The check engine light comes on intermittently. It has high miles so I replaced the oxygen sensor, no change. Unfortunately, I have to have the emissions tested in August and need to get this resolved. Any ideas will be greatly appreciated. Also, are there self diagnostics on this car??

 

Get someone to read the code that comes on with the check engine light. That'll solve your problem.

 

spark plug wires? this happened to our 88 camry that we have.

 

I don't know where you are located but around here (Dallas, TX) you can always find places that will make sure your car passes if you pay them an extra $20 bill. Of course I found this out AFTER I paid $300 to fix emissions problems to make it pass. The next year I found someone to make it pass for an extra $20 - it's certainly cheaper.
