A Timing issue?

[royster]

It wasn't until I joined this forum that I learned a clogged catalytic converter can cause poor performance, and it isn't clear to me why they clog, but some have reported this condition. So actually, the Prep H might be close to the truth. I don't know how you test for a clogged catalytic converter. Best to make sure the timing belt is good, and then that's it's right.

I don't know how you test for a clogged catalytic converter.

You might drive it to a Catalytic Church and see if a Confessional helps.

You can test with a vacuum gage. It will start out the moment start the engine with a high vacuum around 22 or somthing like that. Then it will go lower. down to 19.. If the needle waves back and forth it's got a valve problem. There is a hole bunch if things it can tell you. There is a hole section on testing with one in the UTI manual in the manual section.

With the cover off there is a mark on the timing pulley that aligns up with a pin on the block or somthing like that. I would need to look in the tech section. There is a post in there that shows the marks.
