I have a 95 LS and my CEL keeps coming on and off and my car bogs out but only when its cold once it warms up it runs fine and my CEL only goes if im on long trips and not when being driven in the city, it goes off as soon as you shut the car off and wont go back on for a couple of days, please help.

 

Bump....

 

check the egr valve...

 

egr valve....haha, what is the cel on for

 

well that would be the only explanation for the delayed cel... I had the same issue in a prelude si I replaced the egr and no more check engine light

edit: My bad also called the purge valve in the later model cars

 

other than tha go to a shop and have them plug in there obd1 code reader then search google for a list of codes...
the only way to truely know why it is on is to check the codes...

 

Sorry for not responding quickly, had problems with my dns connection and i took my car to a shop but they were goin to charge me 100 bucks for the obd test so im just gonna do the paper clip test that i herad about, something about your cel flashing long and short need to read up on it, any info would would be greatful, thanks

 

Does it flash or turn on and stay on then shut off?

 

try jumping it when its on. it could be loose wire

 

no it doesnt flash, just turns on and then goes off as soon as you turn of the car.

 

tryed it nothing happened

 

drive it until it comes on (i always carry a small piece of wire in center console), when the light comes on, pull over and check it before shutting the car off.

 

self obd1 test:

under the glove box above kick pannel are two connectors in a little rubber thing that holds them there, pull the one with 2 wires out, take a small paperclip, or wire and connect the wire to the two pin slots (this will jump it) turn the ignition to 2 spot so all accessories are on, youre cel will begin blinking. a long blink is 10 a short blink is 1.
example: two long blinks, one short = 10+10+1= 21.

EDIT: you can do this while engine is running, without cutting the car off

thanks, great help gonna go try this but will it work cuz it takes a while for the cel to come on. And will the test work with out it on, thanks

 

or just take it to autozone or kragen whatever its called in CA, i believe they do it for free if you dont know how to do it

 

it will work with key on engine off if thats what your asking.. It should store the code even when the light is off.

 

autozone and kragen has stoped with the obd tester and renting out as well aslo my ? was will the test work with the engine on.

 

OP take the time to read slowly...

 

use a paperclip to jump your ecu. and yes it will work with the car on.

 

tryied the paper clip thing but nothing happened and now my cars CEL hasnt come back on and it no longer bogs out or anything. Is this good or bad, is it possible for the problem to correct itself or should i be expecting something worse than just my engine boggin out?
