Well the beast decided it was time to throw a code 45 at me a few weeks back. From what i understand this means to rich or to lean. So what exactly is the problem ? bad cat? Thats what i think it is but just wanted to be sure before i went and spent the 300 whatever bucks to replace it.

Thanks in advance for any info.

 

too rich or too lean, my car was doing this because i was running rich, to cure this problem get a o2 sim.

try and get a casper's electronics one, its plug and play

 

drill out that damn bolt son. then replace it. you have an exhaust leak inbetween the sensors.

Yah, that's not going to help at all.

First thing you should do is have an OBDII scan tool determine exactly what DTC is stored in the ECU. P0171 = too lean, P0172 = too rich.

Too lean causes:
1. fuel pump
2. clogged fuel line
3. fpr stuck open
4. fuel filter clogged
5. fuel injector clogged
6. bad fuel
7. bad PRIMARY O2 sensor.
8. EGR (too much flow)
9. valve clearance
10. exhaust leak

Too rich causes:
1. fpr clogged, stuck closed
2. fuel return clogged
3. leaking injector
4. bad fuel
5. bad PRIMARY O2 sensor
6. EGR (insufficient flow)
7. EVAP purge solenoid leaking
8. valve clearance

its really not that hard. he is using my cat. i had the same thing and it is because there are only two bolts in there. the other one is sheered off. just drill it out and put a new bolt in there.

 

Im not using your cat anymore yo. I went to the shop and found my cat. All my studs and bolts were intact. Thats not the problem you weiner. I reset the ECU yesterday and it hasnt come back on soo.... we shall find out.

Thanks for the input shark, thats what im talkin about

Doug you want your cat back ? The exhaust leak turned the flange blue, lol.

 

bah, well screw you too lol.

ill get my cat from you next time im up there, or you can come here for once.
