I think this may be a common problem, but I wanted to come to a forum to find out what some pros thought. When I drive, my car would stall, when I would stop at a red light or stop sign , anything of that matter. My Idle would just drop off. I took it to get tuned, the mechanic adjusted the Idle to about 1k, this worked great for about a week, then the same problem showed up, had it tuned again, same problem happened in a week. Finally I tuned it my self but set the Idle to about 2k -2100 so now the car wont turn off on me, I just have a really high idle and am wasting alot of gas.

Do I need a new carb? Is this a vacum problem? Is the adjuster just keep coming loose?

any insight or help would be much appreciated, thank you


Edit : perhaps I should mention that its a 88 engine in a 89 body accord Lx

 

It's kinda hard to diagnose carb problems online.
Check the hot air door diaphram in the breather tube.
Check the vacum advance diaphrams.
Make sure the choke pull off diaphram is working.
how exactly are you changing the idle speed? The REAL idle screw is on the passenger side rear of the carb.

 

ive been using the black screw thats more in the middle than passanger side, in the back of the carb.
