I have a 95 ford f150 5.0 automatic transmission i think the cats might be clogged shop whats $150 to tell me if they are . I was just wondering if anyone has tired Cataclean if so dose it work and if it dose should I use one or two bottles

 

Yes I tried some in a 2000 Honda CRV. The check engine light came on and the code was something with the catalytic converter. I followed the directions and no longer got the cat converter code.

NOTE 2000 is an OBD2 more sophisticated than your 1995 OBD1, which probably wouldn't have a code for a bad cat converter. Also I wasn't losing power or anything, so my converter likely wasn't plugged.

I don't know if this stuff would work on a badly plugged converter, but if you try it I would do one bottle at a time and follow the directions.

 

Find another shop. $150 is ridiculous to do a backpressure check. Did you go to a muffler shop?

 

Or you can do this yourself. Go to Harbor Freight and buy one of their Laser Temperature Probes for 36 bucks. The max range on them is about 950F. The normal temp on a cat for your rig is between 500 and 800F, Anything hotter and they are plugged. Just take the truck for a 30 minute drive and crawl under it. FWIW, it take temps in the 2000F range to melt the catalyst. An engine that is burning oil will coat the cat and render it useless and will eventually cause it to plug. Hopefully you've not been cramming Seafoam oil down the the intake.

 

did you pull the codes?

If you don't have a reader get the HF reader that allows you to do live data(its 70 bucks), and you can see if your 02 sensors are functioning correctly...

 

Thanks for all the info i haven't done anything yet I just got the truck a week ago its just take a llong time to get up to speed and if i go up a hill it slows down a few people told me to look into the cats all the truck has is the cats then straight pipes

 

Are you capable of doing some wrenching? Get under it, drop the pipes off the cats and beat the guts out of them.

 

Before or after the cat... dose this sound like it might be the cat

 

My main thing is I don't want to keep putting money into it. And not get anywhere

 

As I said before, with cats only and no mufflers, it should be VERY LOUD. If it isn't, your cats are clogged.

It's not that hard to figure out a way to gut them, shouldn't cost you much. If that fixes it, throw a cheap muffler on it to preserve your hearing and keep your sanity, and call it good for now. If you have emissions inspection, you will have to replace them with cheap universal cats.

I'd see about dropping the pipes off the outlets and ream them out with something - then start it, rev it up, and blow all the loosened crap out of them. Reconnect the pipes.
