Hello All,

So a few weeks ago the check engine light and service light started flashing and the car died then and there while I was driving. After some attempts to get it running I made it home.

I rented a scanner from auto zone and it said I had a miss in cylinder 5, and a fault in the air injection system.

I did a tune up and replaced my air injection purge valve I think that's what its called on the rad shroud... and everything ran great as usual but the check engine light was still on.

Yesterday I went back to auto zone and they did the scan and it gave off different codes all together?

P0410: secondary air injection system fault
circuit relay defective or fuse open
check connector and wiring
air pump defective or hose blocked

P0141
Heated oxygen sensor- Bank 1 sensor 2(H02S12)
Open or short circuit
poor electrical connection
faulty H02S12 bank 1 sensor 2

where to start and not waste a ton of money?

Any ideas?

Thanks,
