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?

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.
