ok, on the way to go to a dealership near by my place, just to see how it goes, i revved up to 8000 rpm in 2nd than shifted to 3rd gear.... all of a sudden, the engine light comes on!!! .. so i pulled over, turned off ignition and turn it back on... the engine light came on and went off... which is normal...

what could caused the engine light to come on?? misfiring? anybody with similar incident?
thanks in advance guys!!

What kind of computer are you running. You could have knocked at that RPM.

 

shrug the mysterious CEL. If it doesnt come back after a restart dont worry to much about it. Sometimes the gas cap causes silly stuff like that to happen. At least from my experience and some others i know.

 

DAMN IT!!! CEL keeps coming back on!!! 10 minutes ago, i was ckecking to see if CEL light comes back on... it keeps coming back but when i turn the ignition OFF AND ON it's gone but comes back on again... it just keeps doing that...
only time when CEL light doesn't come on is when the car's idling... what could be the problem? i can't even check to see what code it's throwing since the CEL light goes off when i turn ignition OFF and ON... is there any way i can check the code while engine is running??

to PLAN B: what do u mean by i could have knocked at that RPM??

also i'm using the computer that came along with the motor... 2nd Gen. B16A...OBD I... i've done the swap a year ago... it was just fine 'til now...

thank u guys!!

any experts?

 

ttt.... nobody?

 

Pull the stored code from the computer by using the jumper - it'll be stored no matter if it goes off and on.

My bet, throttle position sensor.
Seen this before.

you could probably rule out a whole lot of stuff if you would just check to see what code its throwing you,does that sound like a good ideal,lol.check the code,then get back to us,then we can get to the bottom of whats causing it.the ecu will store the code and it wont go away till you reset the ecu.

didn't know u could check the codes even tho the CEL is off...
anyways, um....... i'm getting TWO codes...

-TWO long flashes AND
-another TWO long flashes and THREE short flashes... => 20 AND 23
i didn't know u could get 2 codes...

OR maybe 43? but it went=======> TWO long flashes and it stopped for a sec. THAN another TWO long flashes and THREE short ones right after...

thanks guys!!

ok... i came up with these:

23=knock sensor
20=electrical load detector(ELD)<====== what's this??
OR
43=fuel supply system

is knock sensor something that anybody can replace? what causes this problem?
can advanced ignition timing cause the knock sensor to go bad?
sorry if this is a noobie question... thanks...

 

sounds like 20 and 23 ..
the ELD could be becouse of the swap .. and you dont have ELD in the car !!
got the same prob... but runs great thoug im running a US P28 in my EU P28 car witch does not have ELD and the US seems 2 !!!! the knokin thing could be becouse you ign. timing is 2 advanced !!!....

 

have you tried to just reset the ecu yet?reset it first,then see if it comes back on!

 

should i reaplace my knock sensor? guess im gonna put the ignition timing back to normal... i'll try that and get back to ya'll... thanks for the help...

yes... i already tried resetting my ecu... didn't work...
