Sluggish and shuts down

Maybe you should take a trip to your Subaru dealer.

I thought about that. But they are so expensive. Thanks

This one's tricky. If you have a bad coil you'll get a misfire code (PO30x, x=number of cylinder not firing). You can buy one coil cheap online and swap it in easily as necessary. I'd probably replace the old platinum spark plugs with new iridium ones ($30/set online) as the OE plats are fragile to detonation of their anodes. So check the coilpacks and plugs, and if everything is fine and the shuddering continues...especially when slowing to a stop to idle, then the greatest likelihood is that there's a clogged solenoid in the CVT's valve body. These are soldered in, so you have to buy the $800 assy and spend $200 to swap it...plus new CVTF. Before doing that I'd spray-clean the motor's throttle-body thoroughly just in case its idle management is gummed up. Odds are it's the CVT if you've no misfire CELs. Good luck. Ern

@SubaruGuruboston Today he cleaned out the throttle-body and the car did not shut down. I will be driving it some more tomorrow but misfire code p0302-4 did come back up. You guys always hit on the nose. Thank You I will be going back next week and will share this information. I never knew Subaru's were complicated to fix?!
