hi everyone. i am new to this forum and joined because i have little experience with repairs other than basics such as oil changes, rotating tires, etc. i am in a position where i will have to attempt to fix my car myself and have little more than a basic tool kit. (sorry if this a double post- computer is OLD)
so here goes:
* i own a 92 accord with auto transmission
* just about everything in this car is original
my cel came on. got a code 5. 'd4' blinks as well when cel is on while driving (doesnt happen all the time), if that helps in any way. so when i checked my manual, it says it's the map sensor on my car or #21 hose. i checked the prices for a new map sensor, and i'm sure you know it's quite pricey.
here's my issues:
i've kept this car for the most part off the road to be on the safe side, but when i have taken it on a test drive (no more than 1 mile from my place), the cel isnt always coming on. if it does come on, it does so when i am driving. it does not always run rough, sometimes it is fine. and when the cel comes on, then it starts to run a little rougher. when i have seen the cel on, i pull over to get the code reading and sure enough, the cel goes off and i cant get a reading- will keep trying if i put this thing back on the road (i got the reading the first time it came on). is this the map sensor? maybe a hose? a loose wire? (no idea what to look for so i am posting photos) is there any way i can figure this out myself what is causing this? the manual says to check the vacuum but i don't have access to the proper tools. is there anything i can do in my driveway with what i have? is there an inexpensive way i can check vacuum pressure?
i'm posting some photos of the inside of my control box and hoses, such as #21. hope that helps. please bear with me, never done this before.
here's the hoses:
here's the valves:
here's my map sensor:
i should also add that when i had my emissions done a few months back i passed, but was high on no, if that would help diagnose the problem better.
