Hey guys this is my first post but from what I have read so far you guys seem very knowledgable so here it goes. I have a 93 camaro v6 automatic. The problem is at idle it sputters and will sometimes die. It wil idle ok for a while then out of nowhere it will sputter. Then driving it around it will break up and sputter 3k and sometimes at the top of the rpm range. I dont know what to do anymore. The car is NOT throwing my any codes. I changed all the coil packs, the ignition moduale, fuel filter, map sensor and the plugs. I read the plugs tonight and it looked like the car was running lean but could that be from it dying? I dont know what to do anymore. My friend think that it maybe the Cat. I have a feeling like it might be fuel. Please someone please help me!!!!

 

Sounds like the fuel pump going out and/or the pump strainer clogged.

Get it fuel-pressure tested.

 

Also check your fuel filter it might be clogged

 

The bucking started after I changed the fuel filter do you think I may have a bad filter?

 

I don't know maybe if you bought a low quality one.

 

What brand did you use?

You could always try replacing it with an AC Delco one...

 

Some generic autozone brand. I am going to swap the filter tonight and do afuel pressure test

 

I changed the fuel filter and it still does it. I think it might be a sensor. What sensor do you guys think it can be? It still throws me no codes

 

Apart from the previous suggestions:

Spray some cleaner in the throttle body -- get rid of any varnish (good to do regardless).

Maybe O2 sensors...

 

I thought if the o2 sensors were going bad the car would run rich not lean
