Hi, Happy general holidays + New years to all.
The car in the signature after sitting for more then a year and having some exhaust work, has intermittently been throwing oxygen sensor codes, Now this was a while ago so I dont precisley remember the codes, but i do have a Bluetooth obd2 reader and the "torque app" and have been getting some conflicting codes/info. Also does anyone know where a exhaust system diagram of all the gaskets/flexpipes/where the o2
Yes i know i should not be rushing into o2
sensors, so a general tune up after 35k miles is going first
-check for the 5th+ time for vacuum leaks
Here's the codes
signal stuck rich bank1 sensor 1
signal stuck rich bank2 sensor 1
P0306- Misfire within first 1k of revs
And using the test monitor function of tourque
Bank 1/2/4 sensor 4 heater circuit malfunction
Bank 1 sensor 3 is totally dead- i assume this is sensor 3 of 4? pre cat?
Bank 2 sensor 3 , also totally dead.
It also idles poorly and doesnt start well.
I know this is all a shade vague as to why this car doesn't want to idle right, and is also down on fuel economy, but a idea of what o2
sensors are where and where there connectors are would help me actually test them with a multimeter and avoid parts throwing. I am too poor for that
Yes, its a Vulcan
Yes, trans fluid and coolant are overdue
Yes, I checked MULTIPLE times for vacuum leaks.
End of the most typing i have done in weeks. -Mike
