Hi All,

New to the board (but have lurked and found answers on here before, thanks) but I have a question which may send me out of the shallow waters of car repairs.

My 93 Del Sol (1.5) has several issues which may be related:
- Runs fine but every now and then, it will feel super bogged down, and you need to floor it to keep your current speed. 30 seconds later it is fine, but the CEL comes on. This won't happen again during the same trip.
- Did check the code and it is a 43.

Is there a clear answer to this? i.e. Is my oxygen sensor bad?

Thanks in advance,
Greg.
