Rough idle question.
#1
Rough idle question.
I did a search, and came across some suggestions, such as bad motor mounts, dirty throttle body, needs tune up, etc. My 91 crx has kind of a rough idle. I just ran a tank of 93 octane(or 91, whatever it is) of Chevron with techron gas through it, with a bottle of the 4 buck STP fuel injector cleaner. It seems to be idling a little smoother. Is there anything else i could try to make it a little smooter, other than running the same gas again with another bottle of fuel injector cleaner, which i just did? I remeber all of the Hondas we've owned had a rough idle when they got older.

I don't think that's it, because i did that not to long ago. I'm thinking the dirty fuel injectors may be the cause. I remember, when i first got it, at 105k miles, the check engine light came on. It was the fuel injector code flash. I ran a couple bottles of fuel injector cleaner through it, and it solved the problem. It now has 180k. The check engine light has not come on since. Edit: I just saw where you have the same number of posts' as me. And, you joined almost a year later.
