Hello!
I`m new to here, let me introduce my self.
First, I have to say sorry about my stupid English. My english is not good cause I came here to study.
My car is..
Protege5 2003, 148k miles, manual transmission.
I have owned the car 6months, and I gonna sell it 2 months later cause I gotta go back to my country(Korea) which is far away country.
I wish I could go back to my country with my car, but a shipping fee is crazy.
By the way...
I was suffered by p0300(Random misfire??) for a week(And I`ve driven about 500miles with p0300 since I was in middle of nowhere)
So, I got O2 sensor and EGR valve changed.
also I changed spark plugs, wires, coils. And I cleaned MAF sensor.
There is no p0300 anymore.
But P0421 showed up!
It looks like P0300(random misfire) made pre-cat damaged.
So I think my option is...
1. change original one (no way. too expensive!)
2. non-fouler trick (I found O2 sensor extender https://www.amazon.com/dp/ (commissions earned) https://www.ebay.com (commissions earned))
after I get o2 sensor I`m gonna ask any car repair shop to put it in. Cause I have no tool for that job.
3. Change after market pre cat.
I think this one is also reasonable. But problem is there are tons of pre-cat on the web.
Someone`ve mentioned rockauto.com, and there are so many kinds of catalytic converter so I can`t figure out which one I have to buy.
Also if I choose this option, I will go to any car repair shop to get it replaced.
4. getting used CAT.
(I think this one is also good. But I don`t know where I can get it..)
can anybody give me any recommendation? #2 option or #3 option?? Or even #4??
And can you guys tell me about which after market CAT is reliable? (If possible I need exact link or name.. It`s so confused...T.T)
Anyway thank you so much!! have a nice day!
