WHAT CAUSES A CAR JERKS WITH ACCELERATION?

2004 Nissan Altima • 120,000 miles

2004 nissan altima 2.5L jerks with acceleration, then runs fine for a few seconds then jerks with acceleration. Idles fine until you give it gas car will then rev up for a few seconds then idle fine then ev again, no check engine light. It all started when I stopped on the highway in traffic. Went to give it gas and started jerking. Any idea's?

Spark plugs plug wires coils etc is what I would start with checking.

But wouldn't you get a code froma misfire?

Not always I have had plenty of times where there was never a codes set.

There are no plug wires there are only individual coil packs. The car idles perfect until you press the gas

There is still a short boot/spark plug wire that connects the plug to the coil they do go bad sometimes as well. Do a fuel pressure test a back pressure test on the exhaust wouldn't hurt ethier.
