Question about 1997 Honda Accord
Posted by Anonymous on
I've been doing a lot of reading on this code, and I've done the parts replacing as suggested. The thing that is kinda strange is no one has ever mentioned the condition of the spark plugs. I changed the plugs out tell weeks ago and they looked like they were coated in this crusty white powdery substance. Today I rechecked the spark plugs and the plugs were starting to get covered in that substance again. I believe this is the root cause of these p1399, p0301, p0300, p0303, and p0302 codes. My question is, what would cause this fouling of the plugs?. Are the plugs too cold or too hot even. I went with an iridium tipped plug. Was that a bad choice? I seafoamed the engine in hopes of cleaning the fuel system a little. Im kinda baffled with this. I've got this weird feeling its got something to do with the fuel system and its not an electrical problem. Cause, correct me if i'm wrong, but spark plugs wont fire well if they're fouled?

All these code are related to misfiring, the most common problem if you replaced the dist cap and rotor then i would say you have a bad distributor,this is a very common problem the distributors on these hondas cause alot of problems, i would start there.

The P1399 random misfire along with one or more of these codes: P0301, P0302, P0303, P0304 -- indicates a problem with the valves. The B20 engines in the 1997-2001 CR-Vs are known to have problems with valves tightening and then 'burning'.
So the first question is when was the last time you adjusted the valves? If you don't know or never have, then have them adjusted. Soon...
