Question about 1986 Ford Mustang

Mustang stalls when trying to drive and will shut down

I have a 1986 Mustang 5.0 5 speed, the problem is that the car acts like its not getting enough fuel. At first start it will run then shut off after maybe 10 seconds, then after a few starts it stays on. When trying to drive and giving it gas it acts like it wants to stall and starving for fuel. I changed the fuel filter and the fuel pump kicks in before starting...im thinking the fuel pressure regulator may be bad...i did check the fuel line valve and the pressure is low...

Measure fuel pressure on injector rail - should be 38 to 40 psi. If low or fluctuating, then replace regulator. Another possibility is the in-tank filter being clogged - rare I know, but trash in the gas tank and it's clogged.

How do i stop my 1994 ford explorer from sputtering and shutting down when driving at low speed


Not getting enough fuel. There are two coolant temperature sensors one for the gauge. one for the computer. the one to the computer monitors fuel. When it fails the engine is slow to start the first try and there is a strong odor of gasoline. The engine will run rough at some speeds and sometimes stall.

My car will start and idle fine sometime and sometime it dies and dies when put in gear


Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

1994 volvo 940 stalling out when slowing down and turning slow


Check the codes: http://volvospeed.com/CheckEngine.php

These had problems with RPM Sensors, Fuel Pump Relay, Fuel Pump and the MAF Sensors. Also need to make sure the throttle body is clean and adjusted correctly!

Check the EGR for leaks.Here is th emost common cause of idle surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
