ive got 87 accord ,good car, but the pgm-fi lght comes on after about 2 miles . the car runs good , no performance issues , idle unaffected , all works . looked in idiot book and it tells me to take to honda service, sorry due to economic flow thats not in the cards. any ideas or suggestions is appreciated

 

That light is telling you that your ECU is sending out a message regarding the condition of the engine and its systems. I am not familiar with the Accord ECU, but on the similar year CRXs, the ECU is under the passenger's seat.

There will be a binary code in the form of four lights on the ECU. The order and comnbination of lit lights will give you the code, a good factory service manual will give teh decode sequence for the lights on your ECU.

With all that said, I am willing to bet that your O2 sensor is the problem. This is a wear item that is cheap and easy to rplace.

thanks for in put on ecu on accords its on left side of dashboards. heres one for ya now that it has started raining here the light is off. good thing i have lots of hair cause i am pulling it out. am looking in idiot book for codes

 

Um... Well the ECU is under your seat, but there is only one LED that will blink. Its usually hidden by a little plastic door. Fold your seat forward and put your head under the seat, flip the door down and look at the light blinking. If your PGMFI light is on, it will blink.

 

What kinda gas mileage are you getting, running conditions, recent work done, etc. Information is key to giving you a good answer.

 

mileage unaffected ,performance usual, only work done is windshield wipers, just short of oil change ,car runs like a top , all works as before

 

Hmm. Did you check the ECU for blinks?

Only thing i can think of that wouldn't effect gas mileage is the EGR valve being clogged or not working, or the sensor being bad.

 

Maybe your have a dirty, clogged fuel filter or your fuel pump is going bad.

 

Report back the number of blinks from the ecu under the seat.
