Check Engine Light NEVER Stops Flashing.

[JDMChris]

Been driving a 96 MX-3 (1.8 V6 DOHC) and its running great.
Ever Since i can remember, the check engine light has been blinking.

Its not like there is a code showing.. it just keeps on blinking... over and over and over and over... lol
When Idling, When Driving...

Could it be the Aftermarket Gas Cap?

Any Ideas?

Thanks

no to gas cap. have you checked codes before? http://www.mx-3.com/phpBB3/viewtopic.php?f=23&t=34787" onclick="window.open(this.href);return false;

Ive checked thru the codes.. but none fit my situation... it keeps on blinking.. no code... just blinks steadily and never stops.

Also, I have a gas cap... its not the original but fits just fine.. clicks n all..

hmmm, i havent seen an engine light flash constantly, are the flashes the same length each time, all the time?

[JDMChris]

yah i know, its weird.. just keeps flashing constantly. same length in between each time.

Its confusing.. going to try some things and post results

I had a flashing CEL after i did my swap and it was because i had like 6 or more codes, it seems if you have too many codes, it flashes so you pay attention. After i cleared the codes, the flashing stopped even with 5 codes or less.

Well, i changed my alternator, as my sound system killed it.. and the light has yet to come back.

it's a 96.. get an obdII code reader/software.

Constant flashing light means you have a serious emissions problem.

Are you using a KL02 VAF? If not smack yourself on the side of the head then go get one.

noob question but.. whats a VAF?

[JDMChris]

VAF = Vane Airflow Sensor

I didnt know it was on the K8... I thought it was on the probe n ze engines.

Where is that located?

If your CEL is on or flashing, the ecu is trying to tell you that something is wrong. Go ahead and ignore it but you can do some major damage doing so...

If it's flashing, chances are, there are several codes that the ecu has stored. Jump TEN and GRND and pull the codes. If it's egr related, itll throw egr codes.

Ignoring it wouldn't have been the first on my list to suggest in terms of fixing the problem.
