How will I adjust the rev of carburetor when aircon is on?


you don't adjust the idle for any accessories
The idle is set for smooth running of the engine( normally 750-900 rpms with a drop of 200-300 rpms with an ac running so set the idle at the upper rpms and it will still be smooth when the ac is on without affecting gear engagement
your problem I take it is that when the ac cuts in the idle rpms drops and makes the engine run rough
This is normal as the ac compressor takes up to 5 hp to drive it
what you need is an electric controlled vacuum pot connected to the accelerator lever so that when you switch on the ac the power to the ac clutch energizes the pot and vacuum pulls the accelerator lever to maintain the set idle rpms
such an item is found on most early carby operated engines

7.5 l engine. Starts well but idles a bit roughly. Check engine light illuminates intermittently but does not stay lit constantly. Thanks!


If you have a check engine light the best thing is to read the codes and find out what the problem is. Many shops like Aamco read codes free.

Car will start and idle well, idles fine in the different gears. Then when you go to accelerate, about 1100 RPMs it starts surging up and down, but if you go up towards 13-1500 RPMs, it rides smooth. What...


Thanks for choosing FixYa and welcome to the site. I would say it is either the idle control sensor or the map sensor. Usually, with the map sensor, you experience the car stalling out. If this is not happening, I would say change the idle control sensor. If you have a check engine light on, take it to Autozone and have it scanned to make sure.

I have a 2003 ford focus with a 5sp manual transmission, i just got the wheel bearing fixed and now my car idles at regular 1800 rpms, but i lost all power essentially my shift light is always on even in...


If your car lacks power it needs the extra RPMs to push the weight of the vehicle. Most cars idle smoothly at about 700 RPMs. Check the engine compression on all cylinders. If they are all even (within 10lbs) and about 100 psi or more then you may just need a tune up or some work done on the fuel system. Hopefully the engine isn't running hot or has oil control problems which will require some major repairs.

The car runs then when you get to stop light it shuts down then you can start it just when the rpm is low it shuts off


The most common problem with stalling due to low rpms is the idle air control valve. this valve is what controls the idle and keeps the engine at the correct idle this is the first thing i would check and also make sure the throtlebody is clean, most of these type of problems are due to that valve good luck.

Ruff idle on my 2001 for taurus. At higher rpms it runs fine.


It is most likely you wheel alignment (costs about 20 bucks to have your wheels aligned) or try checking the tire Pressure to make sure they're all even maybe hope this helps

Engine stalls or quits running upon excelerating


There is an idle air control valve that controls the idle rpm, which causes the nice smooth idle. When they go bad, it won't idle, jumping from hi rpms to low enough to cause the car to die. The ones that I've replaced were easy to access and replace, usually on the intake manifold area. This will also give you a check engine light. Beyond this, has the engine had a good tune up lately? To check this correctly you should check fuel pressure coming from the pump, check spark coming from distributor. Good luck. Colin
