have recently replaced my car with a used engine, and a brand new catlytic converter.

as i was driving down the highway my check engine light came on. and it spits out
p0420 catalytic converter i just had replaced.....
p0455 , evap cannister is leaking or something liek that
and p0507 high rpm at idle

as for the p0420 the code shot up twice so maybe my mechanic didnt reset the code after he replaced my catlytic converter... i dont know.. eitehr way
any information would be nice. and what do you guys suggest me do

 

p0420 is for a bad o2 sensor. p0507 is for a back cam sensor. Reset the computer and see if they come back.

 

p0420 is the pre cat code bank 1. Which cat did u replace?

 

I had gotten the front cat replaced the bank 1 front catlytic converter.

thank you all i will keep u all updated

 

That's the wrong cat, p0420 bank1 is the pre cat close to the firewall man. Check that along with o2 sensors.

 

i'm going to take a picture of the part they replaced .... its in my trunk

hopefully its just an 02 sensor problem and a gas cap problem, cuz if they replaced the wrong cat i'm going to cry

 

so hopefully this link works

i think thats the cat that he replaced?

 

thats an ac compressor

 

WTF is going on here LOL

 

i got scammed i gotta figure this **** out

 

wow..this can't be real!

 

 

You replaced your CAR with a used engine and brand new cat?

And then what you thought was the catalyst is actually an AC compressor...

Oh my

For real tho I hope you figure it out, especially if you indeed got screwed in such a crazy way.

 

SO NOW I HAVE FINNALLY FIGURED IT OUT,

thanks for all your support fellas, so pretty much brought it bakc to the mechanic and he changed all the 3 cats for like 2000 bucks i believe, and my timing chain tensioners and whatever, its been a long ordeal and its just been hectic .

 

Planecrash?

 

Hows the car running?

 

Car is running great after replacing all the front catylitic converter y pipe, and the o2 sensors, and also as well as did a smoke test and fixed the lines" passed emissions easily. wish i had done it all before.... but now other than that once a week when i put my car from REVERSE TO DRIVE it pauses and jerks into gear, so im going to post another reply to another thread about transmission problems... FML i love my car i dont want to sell it + ive put way too much money in the past 2 years to just throw it out, and its still such a beautiful car. so selling is not an option unless im upgrading which i dont have cash for that.

 

What was the answer to the P0455 code? I'm getting that along with a P0845 code for my trans.

 

This is a good inexpensive tool for reading and clearing SES codes. They have them for android, iPhone and laptop use.
