ok i typed a nice storie in great detail to help explain alot about my car,but never mind the scroll button on my mouse decided to go back pages and erased it to never mind a nice storie.
so any how ill make it fast, my drove nice but after 45mins of drive the pgm-fi would come on and peope from this site told me its me 02 senors which they were right ( thank you) so now im asking for more help.
after i changed the 02 senor the pgm-fi light whent away for about 3 weeks, now the light would come on at high rpms and then after like 5 mins, but now it stays on all the time and i drove my car for 3 days i drive 45mins to skool and another to get back home, but on the 4th day of driveing there it was fine still light on and then i was driving home and i got about 15mins toward home and it started to dogg and choked out, and i can start but it will run for only about or a little longer than 2 min.
now i finally got my car after paying for the towing fee.
so now i can look at my car bu i looked and found the ecu even tho the car repair book was saying at the foot well behide the dash then i finally decided to go with the 86-87 year place which is under the pss. seat and its there but now the 4 lights dont light up at all, is there a way to c watz worng with it without the ecu's lights or a specal way to get it to turn on?
but beside that any ideals at all of why my car will run but then not?

make sure you pull the carpet back from right in front of the led lights and then look at them with the key on and the motor not running. if there are codes stored in there from when your pgmfi light does come on then the lights will light up.. If you want to start fresh and reset the ecu then disconnect the battery for a while and then hook it back up. good luck.

with my old si motor, i know my pgmfi light would occasionally come on but not very often but eventually it would go away. it did not bother me enough to fully look into it.

i forgot to say that when the car got put into the car yard i took my system out of it, so i have it sit for like 2 weeks with out the battery conected,and i finally put one on to take it home and the pgm-fi light was still there but i drove it home.
also tho i forgot to also say that my car has had low idle, like it would drop almost stall but then kick back up and it keeps doing it, how do i fix that and to get my car running w/o the pgm-fi light beging on all the time, or stalling out, or dogging?

Are you saying the Check Engine light is on, but there are no codes on the ECU?

[oeldisplay]

yea the leds dont work on the computer.
the car sat for 2 weeks with the battery disconnected and as soon as i started the car the pgm-fi turned on with the car, im sure that, that should of rest the ecu?
