Help help

 

No experts?

 

3 minute bump followed by 4 minute bump at near 2 AM, cool!
Cleaned idle air control valve, checked for gasket leaks? Code 40 is weird.

 

wait till morning for the experts to wake up..Bump for you. im stumped!

 

help help

 

experts experts!!!!

 

oo and i even swapped my iacv and no gasket leaks

 

what ecu u running and what throttle body do u have on the car or do u have jumper on it

 

i have a stock p28 ecu with a obd2a to obd1 jumper harness
i think its a stock gsr throttle body

 

experts experts please bump if view

 

ugh...

 

dude, no need to bump the thread every 3 minutes. you're gonna get banned if you keep that up...

 

yea really. starting a thread isn't like carrying on an aim conversation.

ok first off there is no code 40... there is a code 4 however. and a crankshaft position sensor being muffed up (which is inside your dizzy btw) could certainly cause something like what you're describing.

 

i put my dizzy on a different car
no check engine light no nothing
dizzy not the problem
so im guessing nobody has had this problem
and sry bout the annoying bump
but this code 40 is annoying cause it dont exist
but my cluster is telling me it does

 

I have read somewhere about this mystery code..... I just don't remember where and what about. daaam.

 

You gotta take it to the Honda Dealership I believe that is what i read.

 

i know im interupting but i have a problem too in my 99 accord i cant go past 5,000 rpm i think my intake mest up my car=[

 

you car is in limp mode. check your check engine light and fix what ever code it is throwing.

 

Automatic ECU maybe?

 

this is what i was gonna ask also.

 

Whoever is "reading" the codes may not be reading it correctly. If the CEL light flashes four times in a quick manner, it's CODE 4....not CODE 40.

 

what is the car doing first off? It might be easier to diagnose by actual problems than a mystery code that could be a ecu problem or something

 

he already said he swapped dizzys on another car and didn't pop up code 4 so his dizzy is good. and code 4 would be for the sensor in the dizzy.

 

its called a ghost code it when the a resistor on the ecu board is burnt or if the ecu is chipped and the tune is not sync it will through a ghost code try changing your ecu and see what that does
