With the choke almost closed your using the vacumn of the intake maniflod to **** more fuel. This means that your engine is running too lean with the choke open. Why? Possibilities are, Fuel pump output to low, Check by disconnecting the fuel line at the carb (this takes two people) hold the end in a tin can, crank the engine. if fuel flow is good then pump isn't the problem if it's just a trickle replace the pump and the filter and you should be good to go. Other possibilities are clogged fuel lines. On an '86 I'd replace them unless they are stainless in which case I'd just blow them out with compressed air. Pinched fuel line, look for crushed areas or kinks, clogged fuel filter, should be an in-line filter near the carb on an '86. Other than that your carb might be set up wrong or in need of a good cleaning ang rebuild. I'd start by inspecting the furl lines and flow and go from there. Sounds like a fun ride! Good luck with it!

Check for air leaks, check the vacuum lines, the base gasket. If everything seems fine then you may have debris inside the carb which is screwing up the air/fuel mixture.

Why stalling out without choke ?


Possible vacuum leak allowing more air into the motor than needed thus the need for the choke to offset the unmetered air. Check for any disconnected/collapsed/broken hoses under the hood

I would check the choke to see if it is close if not try ajusting it by losening the three screws on the right side of carb (passenger side car not running) hold acelerator left side open slitely turn black part of choke to the left till choke just closes release acelerato tighten the three scews if all that is ok check to see if by pressing acelerator with choke open if you see gas squirting (car not running)

My 1996 Toyota Camry is having starting problem. It turns over but won't start unless I floor the gas pedal. Once she's running, she runs like a charm. She starts right up when I'm driving running errands....


all cars have automatic choke system when the engine is cold the choke is automaticall at onn

you must have noticed that when the car was ok and was cold started it use to stay at high rpm and after its warm the rpm reduces

so get your choke settings checked or needs some part to change in the choke system

2001 mazda tribute v6 runs rough cold ildes at about 200 rpm till it warms up then its ok what could it be


I replaced the upper & lower manifold runners seals, now it runs perfect, The reason it runs ok when warm is because the manifolds expand and seal the gaps on the surfaces that the worn old seals are not closing. Also change the spark plugs.

When I acelerate my car wants to choke


I HAVE PERSONALLY CHANGED A FEW THROTTLE POSITON SENSORS IN THESE VEHICLES. BUT BEFORE YOU DO THAT, TRY SPRAYING SOME CARB AND CHOKE SPRAY IN THE THROTTLE BODY WHILE THE CAR IS RUNNING. YOU MAY HAVE TO HOLD IT AT A HIGH IDLE SO IT DOESN'T DIE ON YOU. THIS SHOULD HELP TO REMOVE THE CARBON IN THE THROTTLE BODY. IF IT STILL WANTS TO CHOKE, THEN CHANGE THE T.P.S. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. GOOD LUCK

PCv Valve


Most Positive Crankcase Ventalation valves are located for the valve cover into the intake air somwhere closde to the intalke manifold. They pop out  on both the hoze end and on the valve cover end,with out need of tools. . If you shake a pcv valve and the ball inside you can hear move. It is OK and need not be replaced. I have 188k on mine. It has never been replaced.

1976 Gran Torino motorcraft 2150 2bbl carb. Starts and runs ok at high revs but as choke eases off and revs decrease, engine stalls. Fuel pump OK. Float levels and choke pull off OK. No obvious vacuum...


Are you sure your idle ports ( size of pinhole) in carb aren't plugged with something? What happens if it starts to die, and you give it a quick squirt of WD-40 , down throat of carb?
