Q&A

I have a 3.0 v6 flex fuel

Sounds like the 12 valve OHV engine.

Sounds like plugs and wires perhaps. Coil - maybe. Doubtful though. Have a good diagnosis done ASAP.

will it help if i get all that change the coil, spark plug, and wire. I been driving it for like over a month.

I would have it tested first. Very important. No need to throw a coil at it if it doesn't need one.

My concern is - after a month, damage to your catalytic converters may already be done. You won't know until you repair the misfire.

how much is for a converters to be replace

I would recommend shopping a local dealership - that is the best source for a quality catalytic converter (and in some states - the ONLY legal source...) I'm going to guess - $1,000 - $1,500.

I hope that aint the case

Me too! Start with the basics...

will do that...one more question every time I cut on my AC it always blow out hot air what could be the problem with that..

Could be anything from a system that is low in refrigerant charge due to a leak, to an electrical issue with a cycle switch or high pressure cut off switch, to a compressor failure or compressor coil issue, to a restriction in the lines causing high pressure issues... Too many possibilities - needs a good checking out.
