motor boggs down going up hills. can cleaning the throtle body help?

Spark plugs also should be checked.

I can clean the throttle body and MAF. How do I check the catalytic converter?

I am putting new spark plugs in, boots and springs as well.

On the cat, you can take the vehicle for a ride, get it warmed up to operating temperature, then find a darker area to park while the engine is running and look at the cat to see if it has a orange glow to it. If it does then it is getting plugged up.

Is there a check engine light on? If so have the vehicle scanned for trouble codes.

Thanks. I will try these to see if it helps. I think I am going to end up changing the cats.But I will start with the things I can do myself.

Should I try some catalytic converter cleaner?

Catalytic converts can not be cleaned. They just go bad and need to be replaced.

Thanks

Your welcome, the cats are just something to check. Take care of the other things, you can check on the cats if their glowing or not at anytime.
