OK well lately my engine isn't running right. It idles really low. it seems when I rev the engine that it's sorta miss firing or backfiring. but while i'm driving it's pretty normal until I give it full gas than it either freezes up on me and the v-tec wont kick in or it sputters into the v-tec. When I get done driving I smell like a rotten egg smell to it. What te hell could be going on. Cuz a dude's supposed to buy it in the next two weeks.

 

the rotten egg smell is a distinctive sign that your Catalytic converter is bad. It's the carbon (air/fuel mixture) build-up in your exhaust plumbing that was not completely burnt in your cat.

Replace the cat and it should fix your problems.

 

i believe thats what the smell is from but not so sure about the sputter.. replace the cat like sleep said and tune it up, plugs wires fuel filter everything before you sell.. and lol at my engine is dying, nothing is dying

 

lol^^^^

 

wow i learn something every day.. goodsh1t..

 

I think the sputtering is because the car is in limp mode (no vtec). An exhaust leak or problem with the exhaust problem can cause this...

 

ok well I just put my highflow cat back in. But it was doing that before my cat was in, just not the smell. I put new plugs and wires in about a month ago or less. Is there anything else I could do besides fuel filter, cuz that's a bitch to get too on my car, I've tried before (2.2L)

 

Have you used a OBDII reader to see if you get any code? sometimes the lights doesn't come on even if the ECU registers a code...

I would say go to an Autozone and borrow a OBDII scanner. Know what your problem is before you work on it so that you don't cause more problems/ spend un-neccesary money...
