Apologies for the length of this post, and apologies if this is the wrong place to put it. Also, hello people ! I am new!
I am a 15 year old kid with a 1987 honda accord lxi. Beautiful car, and i love it. The car is in excellent shape as it has only had one previous owner and was essentially untouched by anyone else besides the occasional honda mechanic from the dealership. Only has 136,000 miles on it as well. This car is stock. All original everything. It literally is Grandmas car having only been driven around town by my middle aged neighbor's mother.
Everything is really going well with this car. On the first day we had it, even going for a test drive the PGM FI light came on after about 5 minutes. I summed it up to "Oh this car has been sitting for about a decade, it just needs to be driven". but as time has gone on the light still has not fixed itself.
I drew the line at when i was in a parking lot and the car wasn't wanting to start. I had to turn off the car all the way and wait a few minutes to try again, and even then it was pretty rough start.
It was time to take action at this point. The first thing i noticed was that the light would never come on immediately. I would have to drive the car around for 5-10 minutes before the light showed itself. I'm not entirely sure what that means, but i think it's worth mentioning.
The car would also idle a little faster than i'd like. It would shoot up to around 2000rpm, then i would kick the accelerator and it would drop to around 1100rpm. Better than 2000rpm, but still a little faster than what i'd like. I proceeded to go under the driver seat and count the blinks. There is 12 blinks, and my research says that means that there is most likely an issue with the EGR valve. Okay, fine. I decided to take it out earlier this morning, and check everything. The diaphragm moved smoothly enough and there was only a little bit of gunk inside. I shot it with some penetrating oil and decided that would have to do. I put things back together and called it good. Car started immediately with no stutter. The idle was solid around 900, and i thought things were all good I checked the blinks and sure enough, still 12 of them. I decided to check the EGR one last time. To my understanding, if i disconnect the vacuum hose leading to it, then the engine should stall. So I took out the hose and sure enough, it did not stall. I was a bit bewildered but I took it out for a drive anyways. It took about twice as much time for the PGM FI light to come on, and the RPM started to get a little bit jumpy when it did turn on. When I finally pulled back into the driveway the idle was back to around 1100rpm and wouldn't lower even after kicking the accelerator.
The electrical connection on the EGR was the only thing I didn't check. If you know how to, please provide instructions. How much vacuum should the hose hold connecting to the EGR itself?
That's where I'm at at this point. I'm not sure where to go from here and I'm not a super mechanical kid anyways. I did a lot of research, but if you can point me into the direction of what I should do now. It'd be greatly appreciated.
Thank you
