blinking cel
 

hey guys,



97 d16y8 14b turbo afc dsm 450's 9 psi retarded the timing at the dizzy

coming home from a car show today, the car ran fine until i got into fifth gear. it sounds kind of like a wrx, louder kinda lopey, power doesnt respond like it did, and the car kind of studders in all gears. the cel light comes on and blinks, continiously. going to change/check spark plugs, there is no oil burning smell or color in exhaust. hopefully the afc hasn't caught up with me and i need a rebuild. thanks

Nate

afc is glitchy
it always pull ---- like that
reset the ecu

Re: blinking cel
 

i reset the ecu, no luck.

i pulled the number one spark plug wire while the car was running and it doesnt affect it, all the other cylinders do. moved spark plugs around and no change. ill try to change fuel filter, dizzy cap and rotor, never been changed as far as i know so il start there.

the blinking cel means misfire on one or more cylinders right?

check the code

Re: blinking cel
 

blinking cel on OBD2s indicate missfiring

Re: blinking cel
 

check your O2 sensors, mine went bad and since the AFC was adding in a lot of fuel aready, when the O2 takes a ---- it adds in more fuel, so you then have a retarded ammount, and i causes misfires ;)

also check the IAT sensor cause that will have the same effect

Re: blinking cel
 

yup, misfire, 3 cylinder madness...make sure you dont have a dead 450 too.

Re: blinking cel
 

Compression test that bitch - you are running enough ignition timing to fubar something.

Re: blinking cel
 

yeah but he said he retarded it at the distro, granted the AFC is still advancing the ---- out of it, but i had mine blinking with the hack at 10#'s and no retardedness :1 damn o2 sensor

Retarding OBD2 car at the dizzy is completely useless when the ECU monitors and corrects based on CKF.

Pin the CKF to the CKP, and magically you can retard timing at the distributor. How much can you retard it, again? Right around 9 degrees as far as the dizzy will travel? Well, that's still not enough at 9 psi to avoid pingies and purging coolant into the overflow and a bunch of headgasket problems, and it'll sure make the car feel slow as goat balls out of boost, but yeah just retard it and pretend you're okay.
