XF SC has 1,075 miles on it..

Today i stopped at the Quick-E-Mart on the way to pick up my son from school.. I ran in, bought a coke, got back into the car, and it would not start.. it would turn over, idle very rough and low (around 300-500rpm) then die. After trying to start it about 5 times I did the engine-reset thing by putting the ignition into conv. mode and pressing the gas+brake and the start button - after about 20 seconds, the engine started and seemed to run fine, but I had a "CATS System Fault" warning.. I was afraid to go to my sons school (fearing it would die again) so i drove home and got the Toyota ..

after the XF sat in my garage for 30 minutes or so, i started it up and everything seemed normal - the CATS warning was gone..

Any idea what might have caused this? Bear in mind that it was approx 105F outside when this occured (making it very uncomfortable while i was reading thru the owners manual to figure out how to do the engine-reset).. Just a 'glitch' ?

 

gotta see what codes are set.. may just be a software glitch.. had similar one. no start instrument pack went dead.. pulled fuse then started up.. the engineers still dont know why it did it.. lol

 

What fuse did you pull? you pulled it and left it out, or pulled it and reset it..
