Car Fix DIY Videos

So I have a 2008 Nissan Altima and it sort or makes that same sound except it has more of a rattle to it. I was also told I need to buy a catalytic converter bank 1 manifold. Is there someone that lives in Wilmington Delaware or new castle county that could take a look and see if this is the same problem as this 2006 Nissan Altima here???

David Bunch says:

I keep reading horror stories about the 02 Altima 2.5S and catastrophic engine fails with regard to the 1st cat or pre-cat. If the car is running perfectly well @ 80k miles, would a header to pre-cat replacement fend off any problems?

I also have the same tuype of engine car. it smells exhaust gas inside the car but no fault code yet where do you think the gas is leaking. thanks

its easy to fix and stop the engine management light coming on, it's because the cat is starting to break up and block the exhaust system causing an over rich mixture thats detected by the downstream landa , one of the best ways to fix the engine light problem is to simplify look down the exhaust or up into the manifold and see if it's blocked and running black over rich, if so smash out the blocked cat with a length of steel bar shoved down or up the exhaust system, will mean taking it apart, but you have to be careful not to damage any landa sensors in the process take them out as well if need be, once done disconnect the vehicle's battery to reset the engine management light that's if you don't have a reset tool, once all put back together the management light shouldn't come on and the vehicle will run properly again as an over rich mixture can cause very poor running, to get it through emissions testing next test go become friends with your local garage and bribe them to use another vehicle to stuff the tester up, everybody dose it here in Britain and if you've got the problem you haven't got much to loose by doing this or it's off to the dealership and loose shed loads of money, and the really funny thing is they run better and use less fuel once the cat is gone.

That was a good video and way to go on saving the customer money. Not many mechanics like that anymore.

Tatiana Harris says:

would it be the reason it stalls? evap leak

Tatiana Harris says:

it stalls sometimes and cuts off … it also takes time to pick up and acceleration can you help me with some possible fixs

Leah Poplin says:

Our 2003 Nissan Altima had similar issues. It wasn't making the noise with acceleration, but it did stop accelerating normally. We thought it may be in fail safe mode. Took it to Advance auto and saw the P0420 and P0732 codes pop up. Im researching to find out more before spending too much money. I enjoyed your video.
