OK I have searched around and found a few threads that are kinda close to mine but not quite.
I have a loud sucking/hissing noise coming from what sounds like the intake manifold. It is throwing 2 codes. Both are for each o2 sensor showing high voltage. At idle they read 1.0v but while driving they bounce like they are supposed to.
I have a live data scanner had it hooked up. While driving my fuel trim is fine. bouncing between -3% and +4%.
When I come to a stop it will start to run rich my fuel trim will drop to -30% +. It will start to idle very rough almost stalling out.
So I have not done the Hughes manifold kit yet. I am wondering if this is because my manifold gasket has completely blown out.
Thoughts?
