Smoke test just looking for possible vacuum leaks.

Picked up some data this morning on my way to work. Here are a few shots of my 4 o2 sensors doing there thing. This is at several high way speeds and stops and go.

I finally picked up a infrared thermometer. I will replace the engine oil dip stick tube today and also check the temps on the cats before and after.

These look pretty normal to me.

Thought The LTFT are not suppose to bounce around so much and both LTFT bank 1 and 2 be equivalent to one another?

Adding something esle to this list. I have no check engine light or anything. When I go to read codes, I have a p0703:00 Brake Switch Circuit 2. I have replaced the brakesswitch with a OEM unit around a month ago. My brake lights are working as they should. Where should I start looking for this issue. One thing after another with this baby.

I don't see LTFT data there. I only see O2 sensor data.

might be misaligned, check that it works every time you press the pedal, then clear the code and see if it comes back. this is one of the things I do not like about the brake switch design, the switch can be moved instead of being locked into a single position

• Faulty Brake Switch
• Misadjusted Brake Switch
• Brake Switch harness is open or shorted
• Brake Switch circuit poor electrical connection
• Check if the stop light works with the brake pedal
• If the brake lights are inoperative, replaced or adjust the brake switch

Opps im sorry. Im all confused with this. I am learning as i go with this scanner and trying to do my own diagnostics. So both sensor 2 on bank 1 and 2 are reading good?
