I have this problem still, have taken to the dealer ten times over the last Five years, after one week check engine lights comes back on they again replace the egr and the light comes back on, I have given up on them fixing it can you recommend a solution to this problem, Honda cannot.
This stupid check engine light kept coming back after the mechanics replacing the EGR Ports/catalytic converters and nothing seem to fix it. It is so annoying, now the car is 212000 miles and I am giving up on this issue.
Car would stal when you slow down or touch tne brake. Had egr replaced twice in one year and now doing it again ?
Replaced EGR valve and had to get clogged EGR ports cleaned. Also had to replace catalytic converter.
brought my 1990 accord for smog but failed due to "wrong timing" so brought it to a mechanic after testing the car with their smog machine...they said i have a bad cat, as i drove off the shop... the check engine light came on and won't go away! every time i start my car, it won't show but after driving a couple of miles.. check engine light will come on again. now i don't know how am i gonna pass smog~
check engine light was on.Not running right very rough.Put new egr port in.
Engine light came on...cause catalytic converter. It has over 250, 000 miles on it now...light still on...never got it fixed. Dealership wanted $80 just to hook it up to computer to see what was wrong with it! I already KNEW!!
The check engine light with code P0402 came on around 112900 miles. This problem is because of the engine computers threshold calculated by the 2 oxygen sensors. Accords from 1998-2001 have a much closer tolerance than other year models so as the catalytic efficiency becomes less, these year model accords trip the check engine light. I tried a CATCOE $310.00 brand catalytic converter and got about 20K miles before the same problem came back. I have sense changed it again using a converter from Autozone $190.00 and after 30k miles no problem noted. Always use Honda O2 sensors or Denso brand. Never Bosh
Check engine light was on and could here the cat s had it changed. after 23 miles light came back on. code said insufficient flow. mechanic ran diagnostice and said the wires were loose on egr. tightened wires. light back on after 23 miles. reset the light came back on after 60 miles. mechanic wants $300 to replace egr
They replaced the EGR filter.
The cat rattled when I purchased the car, allowing me to get it for pretty cheap. I drove it for a while, until the car was so down on power that I couldn't keep up with traffic. I had it repaired for about $300 at a local shop.
Feels like its missing has new plugs o2sensor,new egr valve
Jerking ,stalling not fixed
Turns out catalytic converter cylinder was EMPTY! Guess all the filter stuff was used up! Had no idea that ever could happen. Another hit for the credit card.
fixed motor mounts car running good in march butengine lite staying on plus s lite keeps blinking reminds me of left turn lite drives me crazy
engine idle speed very low and p401 code set
I Had this problem and had the intake manifold ports cleaned out and the problem was solved - but of course the catalytic converter was changed and o2 sensors and erg valve. Car was totaled this weekend by someone who got their drivers license at K-Mart.
need a new cat; haven't decided to sell or repair
Replaced catalytic converter and light is still on.
Having problems with tat now.
