Good morning,

i was driving under normal condition. around 40km/h or so

anyway, the Check engine light came up but everything was running perfect

am having a problem with knocking though its not that big.

i tried down shifting, high rpm, flooring it or abnormal but didn't notice a thing
i even check the fuel cap if its tight and it is.

its a 1998 camaro Z28 i have 127000 KM done
LS1
any ideas ??
thnx

Use a code scanner to check it or hit up an autozone etc so they can pull your codes

Pulling the codes is your only option. a check engine light without any symptoms is impossible to diagnose.

if i have low oil will it trigger check engine ?
or it is set only to trigger when there is a problem with emission system.
because i removed the catalytic converters before but already took it to a programmer to do his thing with the o2 sensor

have the car scanned for the ses code, or you can get a ok scanner from harbor freight for $100 on sale.

now that i have let the car rest and cool down over night i checked the engine level and its low, the oil reaches till (ADD)

ok so i went for an oil change ... it wasnt low but it was dirty now the light is off thank god

This will not fix a check engine light. There is an oil change light, which will come on for a needed oil change.

You probably still have the codes stored in the car's computer. You should get that scanned to see what the problem was. (The condition may have temporarily gone away - but the odds are that it will come back.)

You should be able to buy an inexpensive scanner, which will pull the codes for you from the car's PCM. Form there, you can find out where the problem was by looking up the code.

Probably nothing mechanically wrong

@wssix99 i dont have that light in my camaro but i di have low oil pressure light and my camaro dont have the service reminder light and even doesnt have the oil/trip holding method to reset it ... i hope that it doesnt come back and i'll take it to my programmer to see what triggered it

JUSTINSWS6

To rest the oil. Turn key to on do not start press the pedal to the ground three times.
What is your oil pressure at

bahrain z28

it is low but it is in the operating range.

its been like that since the day i bought it, or even the pre-owner did

when the oil is warmed up it give me 20-25 PSI idling

consider that i live in Bahrain
Weather temperature is around 40-48C

JUSTINSWS6

Thats not right. Check the pressure from a external gauge.

bahrain z28

how to do that i can get an external pressure gauge but i have no idea how to use it

bahrain z28

anyone?
