Decat problems
I recently fitted a Japspeed decat pipe with a CEL fix screw as i was under the impression that no CEL lights will appear... but...it did!
The codes found were: P1399 - missfire P0420 - Cat below Efficiency (as expected) P0301 - Cylinder 1 missfire P0302 - Cylinder 2 missfire P0300 - Random / multiple cylinder missfire I had my CAT fitted back on and the codes cleared, went to drive away from the garage and another CEL light appears - any ideas what this could be? |
possibly damaged the o2 sensor? :shrug: Or the cel fix doesn't work as designed. Got pics?

No the CEL fix didnt work lol.. Pictures of? |
Strange for you to have issues on a MY01... RedCelica was asking for pictures of the test pipe and CEL fix. Is it just the long mounting tube for the sensor that pulls it away from the test pipe?
Misfire codes such as those have been tied to bad O2 sensors before. However, I thought that it was the primary O2 that caused this, not the secondary O2. |
The test pipe is this one: http://www.japspeed.co.uk/Honda-S200...ipe/p-8-1-156/
The CEL fix screw is this: http://www.ebay.co.uk/itm/1109947030...84.m1497.l2649 Would the ECU adjust itself if i were to keep driving it? I know some cars have the ability to do that. |
S2000s do have the learning type ECUs although I don't think it'll adjust itself over a misfire or a CEL for that matter.
|
Any suggestions on what to do?

Just had the codes looked at, same as before - misfiring with no obvious cause.
Codes have been cleared and not come back yet.. |
Can you feel the car misfiring at all? Stuttering, shuddering, hesitating?
|
I am going to throw this out there... A local guy had a shop put a test pipe in for him (under the table of course) and they put the O2 fix in the wrong spot... Did you install it yourself? i would check to see if they put the spacer on the first o2 sensor for some retarded reason. Also check to make sure they didnt snap one of the wires out of the sensors...
