Hello. Car runs great, for an hour, sometimes 2hrs, then when stopping, starts idiling very low, then almost stalls. Unless I give it gas with emergency break on, it would stall. I am suspecting a carburetor adjustment????? maybe something was knocked loose when I went too quickly over a ditch/bump a few days ago.

I'm trying to get ideas before I break out the screwdriver. Thanks!

 

Basic stuff: air filter, fuel pump would be my first guesses after carb adjustment.

 

A fuel filter would help too, but probably has nothing to do with the problem.

Try the easy fix first, adjust the idle up. If that doesn't work, it could be a carb problem. Has it ever been rebuilt? A carb that old would probably need it by now.

 

Change the idle screw on the throttle bodsy, it should be a gold screw.

 

With the '84, this could easily be a vacuum hose problem. The SI (I don't know about the others) had over 84 vacuum hoses, and two plastic boxes filled with little vacuum components. I took mine to two dealers and they both told me the same thing. When an '84 CRX gets a vacuum problem, it's time to throw it out. I replaced almost all the vacuum hoses, and tried a bunch of other things, payed a dealer over $1500 to try to find it, but to no avail. I wish I'd saved my money for a new CRX, or at least a new engine (without the vacuum hoses this time).

 

That's why I reworked the vac system on my old '87 Si. I took it down to less then a dozen and it ran peachy.Or, give it to someone like me.

 

carbureted engine, buddy

 

The '87 is a lot easier to deal with than the '84. The 87 is fuel injected, and the vacuum hoses are kept to a minimum. Try that with the 84 + hoses in an '84.

 

Only the Si. All other models still used a single carburator. There was no '84 Si, just an S (the little "i" means it's fuel injected.)
