code 13
while driving in traffic everything is fine.When i get on the highway and cruising in 6th gear, within 2 minutes i get the check engine light.Is it possible that the car goes back to open loop because of the lower water temp and exhaust temp from driving 1700 rpm for a while?Water temp is around 165-175.I have changed the o2 sensor two times but the same code appears.Maybe my o2 sensor is falling out of it's operating temp because i have no backpreassure in the exhaust system(no cats no precats).I have this problem for a while now and can't figure it out.Thanks in advance for any info
