any know what that is i looked at the form and their is no listing for it but it is in the vtec section? https://honda-tech.com/zerothread?id=978933 their what i looked at

 

just did some rescearch and what i found was a multi cyclinder misfire is that right

 

What Car? Year?

 

2000 integra gsr

 

any one does it have to do with a multiple cylinder misfire help 2000 teg gsr

 

could not find it! sure its the correct code?

 

Thats the right code, it comes along with p0300 p0301 p0302, p0303, etc...
You may have a vacuum leak, a bad tune, bad injectors, bad plugs, or 1000 other things.
Any other codes?
I got this code recently after installing the turbo, but after resetting the ecu and calibrating the wideband, the code went away for good. It was a problem with the fuel trim and I was leaning out badly during idle-warmup.

 

just had injectors replaced plugs replaced wires replaced cap and rotor replaced both o2 r bad could that be the problem replacing o2 this weekend

 

Only your primary O2 controls the fuel trim, the secondary only throws CELs for bad cat.

 

Where did you get that p1399 comes with random misfire?? I have ALLDATA and Mitchell On Demand and none of them have it? just wondering.

 

I just knew it from memory but here is some data:

P0301- Cylinder 1 misfiring
P0302- cylinder 2 misfiring
P0303- cylinder 3 misfiring
P0300- random / multiple misfire detected.
P1399- Manufactures control Ignition system OR Misfire

I think p1 codes are mfgr specific and don't always show up in OBD2 code lists.

 

Where did you get your info. from? wondering?Thank's

 

well, from memory... (I had to figure it out myself) but I found that info on this site also. Here's one link:
https://honda-tech.com/zerothread?id=796378

 

One more bit of info, p1399 does not throw a CEL (at least at first it doesn't), the P03XX codes throw the CEL.

 

Ohhhhhhhh... ok, but the info you got is from a different motor. He even wrote that he is not sure what ECU he has! All ECU's are different. Iam sure he is wrong.

 

Well thanks for the info. but iam sure that code does no exist atleast on a 2000 acura integra! Thanks again.

 

Actually, this was on my 2000 GSR. The mysterious p1399 code is a REAL code... random misfire. Simple as that, it's a mfgr specific OBD2 code.
I can guarantee this as 100% fact, as I pulled it myself from my 2000 GSR with my code reader.

 

The shop manual says look for the other codes. If there are any, troubleshoot them first as they are probably the cause of the misfire. If not,

Honestly, if it's a pending p1399 code and you don't have a p030X or CEL, then it was probably some bad gas.

 

yeah getting some mis fire weird though i just replaced the wires with bosch cap rotor and spark plug i was told bosh was junk and i wasted my money im just going to buy a new disturbuter and some ngk wires and if that dont fix it i dont know because i just replaced the injectors and fuel filter thanks

 

Any update, im getting the same 0301, 0303, 1300 and 1399 codes
