Sometimes years of doing something does not mean you had the correct experience. lol
Your response content has been mostly youtube and internet copy and past info and generally no pictures of anything about you? Strange ? And for a guy with a background ??
I do see a little mechanical experience with a few of your responses but most of yours is out of the 70 at best mid 80's.
Anyway Xylene(or other of the same category) is not for the causal user but defiantly not advise to give as you did for this thread and the OP with the possible CAT problem

 

Their all very toxic products including Toluene. Inhaling the fumes can easily land you in hospital and unless you know what your doing and how to hanle them DON'T play with them. Oil companies sell low aromatic petrol in country areas to stop kids getting high (and dying) by inhailing their products.

 

Now you are reaching for anything to try to save your bad information on this thread.. hahahahaha!!!
Dude you just don't stop do you. You might look up the toxic material that is created from the tire wearing on the tarmac.
Or how about just filling your gas tank.....LOL

I am very sure looking in your garage as well your truck we could find some very toxic chemicals that you use. lol

 

 

Your knowledge generally from what I have read is like your signature (Always use quality parts not landfill)
You just don't understand the world.
And at your age that's just sad.

 

After all that I rang the exhaust shop asking how much to diagnose it pin point the cat they said they would do it for free.i ruled out the egr circuit at least that's all working fine

 

That's great to hear. Good to see there are still some decent shops out there. Please post the outcome.

 

I'm thinking pcv valve might be an issue now of why the cats are blocked I been eyeing it off since I got the car because iv had to replace all the vacuum hoses because they were deteriorated ..but it's hard to get to so just left it also come to think of it I got oil around the starter motor so might be leaking from pcv hose

 

Nothing you posted suggested a PCV problem

 

My response was that simply OBDII started to be used in 1995.
I didn’t look up if there were any auto manufacturer didn’t use the newer ECU standard OBDII. But looking some Mazdas sold in Australia did in fact have the OBDII and that it was simply delayed as mandated to use it starting in 2006.

Yes Scotty was getting old … and started getting eccentric with some of his info tubes.
