Hey guys, 2003 Corolla 200,000 miles, so for the past couple of months my cars been having a hard time starting. The odd thing is that the first time you start it it will take a while but if you go out and start the car again and hour later it'll start fine. But after an 8 hour school day, it has a hard time again. Thought it was the spark plugs so those were changed to NGK Iridiums but still no change. Battery test is clean. OBD has P0133 error (Bank 1, Sensor 1 Slow Response). Halfway through the start up it sounds like it starts but goes right back to cranking. Could the O2 sensor be the culprit? Does anyone have any ideas as to what it could be?
Thanks.
Thanks.
