The cats are junk so we already bought new ones. The O2 Sensors I am sure will not be the best after this so they are on the list as well. I priced a bunch of stuff out and so far I am hitting $800 for most of everything including a new radiator since that has some pin holes.
The engine runs horrible. Practically stalls out when you drive it and it wont rev over 4000 rpm. Shifts all screwed up. I will be doing everything once I am in the engine.
What do you mean VQ?
He said the matrix of the cats were clogged up. I will be checking compression before I do anything. It idles fine, so I would probably let it warm up a bit before doing a compression test.
It ran perfect before this. This happened within a a week or two.
I used to work on engines all the time but I got out of it for a while, especially after selling my Mazda Rx7. Easiest engine to work on. So we usually bring it to our mechanic to have him check stuff out and do the work if its not to expensive.
Check to make sure the butterflies didn't fall into a valve.
Not knowing to much about this engine, only butterflies I know of is the throttle body. Any where else use butterflies I should be aware of?
