It has 112,000 miles on the odometer. After the car has warmed up, the engine begins to miss when idling. I don't notice it when traveling down the hi way. I took it to a mechanic the other day but it was only a 2 mile drive to his garage and it didn't do it then. However, after traveling several miles yesterday, the engine missed each time I came to a stop. I changed the fuel filter last week. It had new plugs and plug wires 14,000 miles ago. I add injector cleaner at each oil change (at 3,000 miles). The check engine light does not come on. If it was a problem with the injectors, wouldn't it miss 100% of the time? It is puzzling that it only does it after being sufficiently warmed up.

Scanning the PCM should tell you. With that said; If it runs okay when cold, but starts running rough when warm, you may have a vacuum leak. When the engine is cold, it runs rich which in turn can 'mask' a vacuum leak. As the engine warms, the fuel delivery leans. But, if it is a vacuum leak, I'd think that the O2 sensors would be picking up on this. Same with a faulty pressure regulator or an injector problem. When you turn the ignition on, the check engine (or service engine soon) lamp should be on, then go off after a few seconds when the engine starts. I'd recommend having the PCM scanned (with live data).

I'm surprised because the set was new not that long ago.
