Code 435 AGAIN!!! 850 Turbo 1995

Hello my friends,

My beloved 850 shows up the 435 code again. There's a easy way to detect air leakage or I really need to open the hood and tigen every single nut and bolt in the intake/exausth manifold and vacuum system? Something like a smoke, we pump it in the intake system and wait to see the result.

I'm thinking in replace the front OS sensor and see what happen.

Thanks.

If you've already checked vacuum lines, etc, I'd go after the O2 sensor itself for that code.
