SOURCE: engine stalling in park and drive.

Just a shot in the dark here. Mikuni carbs were problamatic on that engine. I remember them well. They had internal vacuum leaks and diapragm leaks just like you describe. I dont kn ow if you can get it any more but the fix used to be a new reman carb. they were not rebuildable. But I always wondered why you coul not have a base plate adapter made by a machine shop to adapt any other simpler carb to it? as long as your cfm rating was the same--ya know? Like take a holley 2 barrel off a k-car and adapt it on. Anyway I hope I helped. But that is what it sounds like. Carb replacement. Thanks

Start by cleaning your throttle body.  May need an Idle Air Control valve.

Check and clean the idle control solenoid and passages, check the throttle position sensor and perhaps the crank sensor. Don't buy anything without testing or you will be spending money on stuff you don't need.
If stumped, get a chiltons or haynes manual and go through the test procedures they outline. Any good shop does this and you should too!
If it tends to stall that tells me that the iac is possibly opening late (sticking) but that can also happen if it gets bad information from the control system. (where testing is important)

My 1997 subaru impreza is revving like crazy on start up, accelerating and then losing power when drive without me touching accelerator?


First, make sure your airfilter is not plugged. If it is, the engine is compensating for the lack of air intake. If not, consider replacing the Idle Control Valve. Inquire with an auto parts dealer (store) for this part.
Please let me know if you need further assistance.

Air conditioning causes car to idle or die.


Depending on whether your car is Injected or Carby induction, The aircon system has an IDLE UP circuit which is supposed to raise the Idle while the Aircon Compressor is engaged. The Compressor cycles on & off to charge the system pressure as required. The Idle up system typically uses an IDLE UP SOLENOID which is usually mounted directly on the throttle linkage at the Carby or Throttle body itself, or a Vacuum Solenoid which switches vacuum to a Diaphram which is connected to a linkage on the Carby or Throttle body itself, or a Vacuum Switch which ports air into the throttle body to raise idle (This type on injected vehicles only). It sounds as if the IDLE UP system has failed or is not adjusted properly. Revving the engine spins the compressor faster thus charging the system sufficiently to dis-engage the compressor, which in turn removes the load from the engine, allowing it to idle again. A simple way to test is to disconnect the Aircon clutch wire (make sure it cannot fall into belt) & switch on the Air with the engine running. The RPM should raise typically around 300 RPM. If it doesn't the IDLE UP is not working. Hope this helps.

Idle


i strongly suspect a vacuum leak.. check for disconnected hoses or intake area leaking by spraying carb cleaner around those areas while idling.. if engine personality changes you are close

Subaru impreza uk model wrx stalls and low idle, hesition


try adjusting the throttle cable, its a case of loosening a nut, pulling the cable through a bit more and then tightening it back up, you find it on the right hand side of the engine block close to the exhaust manifold.

High revs and surges when driving.


The revving to 2000 then dropping the 1500 likely means that it is in "limp home" mode. When there is a serious problem, the car will put itself in this limited mode to avoid further damage, and to get itself back home without stalling (hence the name). Since it stalls, its likely that there is a serious problem with the fuel system, and the limp home mode will not help you any more since you keep driving it like that. 
As far as the problem goes, it could be just about anything. Almost positive it has to do with the fuel system, but could be so many different things.
Hope this helps!

1988 F-250 460 engine stalls when dribing down the road


On older, carbureted engines, cold stalling (and hard starting) is most often due to an automatic choke that is sticking, misadjusted or broken. Cleaning the choke mechanism with aerosol carburetor cleaner may free up the choke allowing it to work properly again. If the choke housing as an electrical heating element, the element may not be receiving voltage when the key is on, or the element may have burned out (check resistance with an ohmmeter).

Other causes of stalling with a carburetor include an idle speed adjustment screw that is set too low (turn screw to increase idle speed rpm). The engine may stall if the idle fuel mixture screw(s) are not adjusted correctly or the idle mixture port(s) are dirty or clogged with fuel varnish deposits (clean the carburetor and readjust the idle mixture screws for smoothest idle). Stalling can also occur is there are vacuum leaks in the carburetor, under the carburetor (bad base gasket), or any vacuum hose connections to the carburetor or intake manifold
