I have a 01 Honda Accord that I just bought and it has been giving me problems,it will run a week or two and then just quit on me! I changed the distributor cap and it was fine for about two more weeks and quit running again! It will crank and run but will die within a few miles of driving it! I also borrowed a scanner from a friend and Im getting a P0420 code! Can this be my problem? Thanks!

P0420- catalyst below system threshold. which means
The cat has lost its efficiency and can’t clean the
emissions. The cat o2 has a problem or the cat is clogged
or busted inside and needs replacement.I don’t recall the catalytic converter not functioning properly, afflicting a no start condition.
Please enlighten me if it does.
Thank you and Im not really sure myself,I did’nt think that it would either,and I will let you know what I find out!
Redneck,
While car is running do visual of the cat and see if its glowing red-it shouldn’t be.
Next while car is on hit the cat with a mallet a couple times and step on the gas because if partial clog it’ll spit out of ur exhaust.
Also if u have an IR thermometer take the temp before and after the cat-a big difference will indicate a clog.
Lastly my buddy did have a 95 sl1 that hada cat clogged so bad that he finally tried cutting it before the cat and voila it started[quote=”Emphasis” post=60157]I don’t recall the catalytic converter not functioning properly, afflicting a no start condition.

Your right it was a long day and I was tired. Lets try again.
Thanks College Man, I have watched all of these and I know Its going to be one of these things thats wrong with it,I have yet to narrow it down to which one that it is. Like I had said in my first post, I changed the distributor cap, and thought I had the problem fixed. But once again it messed up! I have noticed that it only breaks down on me on really hot days,and it takes anywhere from five minutes to a couple days before I can get it to crank again! That leads me to believe that it might be the coil or the main relay. It just threw me off when I hooked it up yesterday and got the P0420 code.
Ok guys I unhooked the battery and cleared the P0420 code and I ran it some and it has not showed up again,so that leads me to think that it was just an old code left in the computer. But now heres what I got,I ran up the Rpm’s to heat up everything,I got to 2000/2500 Rpm’s and let it come back down and then it shut off on me,We checked the fireing at the plug wire and wasnt able to see spark,and checked at the coil,and saw spark. So we changed the rotor button and put the cap back on,and it still did the same thing. But my dad was standing in front of the car and when I reved the Rpm’s and he relized that it was flooding,I got it un flooded and I cant get it to shut off! Does anybody know what might be going on? Cause this is just confusing the crap out of me?
If the car won’t shut off with the ignition switch off.
The the electrical portion of the switch is bad. Replace
the electrical portion of the ignition switch.Hey sorry about that I worded that wrong it will cut off with the switch its just that I couldnt get it to cut off as far as breaking down again!
