Hey Thanks for the advice Ken
So I looked for my cat converter and it was bolted on under my exhaust manifold and when I checked I found that it was changed when I had installed a new engine( it came with the engine) There isn't much of a rattling noise.
There is another box in the middle of the car I think its the resonator, could this also get plugged, there isn't a rattling noise from it.
I also removed the O2 sensor in the exhaust manifold, when I rev the engine a lot (usually at 3000 - 3500rpm) there is a backfire noise that comes through the O2 sensor hole.
Is this normal?
Also if I change my fuel filter, which I plan 2 do first, and there is still the problem, Any advice what could be the problem.
Could a bad sensor cause this, if so which one most likely. Remember the problem is only up hill and the car works great on flat.
