Hi all, I'm having some issues with my 22RTE. I've been doing a lot of driving around at speeds under 60mph, and so much has been wonderful. I recently started a new job to which I commute 10 or so minutes on the highway. I am now experiencing issues at highway speeds between 65 and 80 (haven't gone above that). That is when my RPM range is in the 2300 and up range. It feels as if I am hitting a divet in the road every second or so. My wideband has a graph readout option, and at those times it looked like saw teeth. Usually traveling at a constant speed, the graph is fairly flat. I've been playing around in the driveway, and sure enough I am having issues with misfiring around the 2300 to 2700 RPM range. My first suspect was the TPS, so I unplugged it, and the problem persisted. I have a new fuel pump, new fuel filter, and everything ignition wise is new (plugs, wires, cap, rotor, coil). I'm trying to figure out what the issue is. Have any of y'all heard of this? have any of y'all experienced this? I would love to take some road trips to remote areas again this summer, but am afraid of an engine that can't go above 60mph. thanks for any input!
