2004 LX with 212K. Half the time on start up the RPM will dip down to 3-400. Occasionally it will go lower and stall out. When this happens I will get a gas smell in the cabin immediately.
My codes are included from Torque. I've replaced the gas cap with a Toyota cap with no improvement. Last week I replaced the original Denso 25860-50100 evap vacuum switching valve under the hood with Dorman 911-488. I thought it helped. Codes actually went away. Then rpm dip and same exact codes came back a few days later. Does this sound like my Dorman valve went bad in a few days? I've had good luck with Dorman in the past should I pay double for the Denso? Does it sound/look like something else from the codes?
Thank you I've been scratching my head on this one for a while and I hate throwing parts at a car.
