I apologize if this has already been discussed to death, but I think that I have a unique problem. I have a honda accord 87 lx manual.
here is the deal:
First thing, the idle is almost always too high (or shows too high, as I can't hear it well when it shows 4500rpm - it sonds much lower. ) Sometimes it gets back to normal after a long time driving - for like 30 mins
Then the car is jerky sometimes when I press/hold the accelerator evenly. Then, it smokes too much most of the time at cold start, but I think that's just 'cause its too old (220,000mi)
But the real problem is that sometimes it takes 15mins to start the beast :mad: And the idle can't hold itself - and the car dies.
But here is that unique part: ALMOST ALWAYS the starting/idling/ stalling problems are in warm temp weather! When it's cold - starts/works fine.
During the spring/summer time (now), can't start it. When I do start her up, she doesn't hold the idle! So there I am- sitting like an idiot revving her up for 10mins so she doesn't die. And that doesn't always work - you driving, pop in the clutch, and she stalls at the worst moment :(
And the next time I start it (after 15-30mins being off), I have to do the same thing to hold the idle. Sometimes works ok and she doesn't die on me, but always jerky during the summer.
I tried to look for bad vaccum hoses, but I don't know how to, and there are so many! I tried to adjust the O2 sensor for high altitude (the one on the left of air filter - little box thing with a screw-like adjuster) and it didn't seem to help either way. I used the carb/engine cleaner a few times, but I think that all it did is eat out the joints of my muffler
I tried to see if I could adjust the carb somehow, so I took off the air filter, fooled around with the valves - didnt help. Sorry, but I'm not too mechanically savvy.
I took it to a "mechanic" all they did was rider her for 30miles, run some "tests" and say that they don't know-that junk is not for them! Their "test" said something like (don't have it with me) 3rd cylinder isn't getting enough fuel or some sort, but I think it was just so I don't feel bad paying the $50.
I replaced the spark plugs a year ago, they seem fine. Just replaced the air filter/oil.
Now, I read through a few posts, and the solutions seem: replace bad vaccum hoses, the ERG, PVC valves, coolant??, fuel filter(s) (changed both), or do some carb tinkering.
I think that I need to change some stupind temp sensor or some rather - I hope so.
Please guys, help! I've struggled with this problem for 2 years now, and don't know what to do next (well, I don't want to spend the $200 by going to dealership). I've changed almost everything there is to change in her, and plan (need) to squeeze out 50,000mi more, but this carb problem is really annoying.
Thanks in advance
