1999 rv with ford v10. Starts good, idles good, runs good FOR 5 MILES..then if it idles , it dies...still seems to run ok as long as the rpm is over 1000 (IDLE). Ford shop says needs new fuel pump.


Did Ford tell you the pressure of fuel was LOW? They should know what they're doing.
Does it have an idle air control valve (IACV) ? Have you cleaned the MAF sensor? don-ohio (:^)

84 mustang 5.0 auto-Idle problems. runs Ok when cold , runs rough and stalls when warm. 1st year throttle body injection. was told the IAC valve needs cleaned. can`t find on car


the iac sensor is along the side of throttle body , did you give the throttle plate area a good cleaning out this is where the air path is for the IAC sensor , a lot of idle problems have been fixed with a can of throttle body cleaner and few good squirts of the stuff down the hole

1985 celebrity starts and idles then starts to idle higher and higher what:'s wrong


Sounds like either a vacuum leak, a TPS throttle position sensor, an AIC air idle control valve, or worst case scenerio, an intake manifold gasket. Try spraying brake cleaner directly onto intake manifold at the gasket. If idle lowers, that is the problem. Also spray all visible vacuum hoses and listen for idle drop. Listen for air hissing as well. Good luck let me know if these are good tips

High idle after engine is warm. nothing is sticking with linkage.1992 chev k1500 5.7


Make sure the idle screw was not turnned causeing tps sensor to read over the spec limit, the next then is to make sure the idle air control valve is working , a bad valve will cause this problem and last is the stepper motor that controls the idle. some of these around this year used steeper idle control motors instead of idle air control valves and in turn the stepper motor is bad it will hold the throtle plate open to much causing the tps reading to be wrong triggering the engine light to come on. the steeper motor will be boltted to side of the throtlebody and theres a small arm to the throtle linkage. i will enclose a stepper motor picture and an idle air valve to show you, but this sounds like the tps is out of range due to this. the last thing is to make sure there are no vacuum leaks, spray crab cleaner around throtlebody base gasket and also the intake mounting gasket and see if the idle changes is so theres a vac leak in that area. good day. okay just did a little research and this truck does have a idle air control valve, the picture is encolsed and is screwed into throtlebody, check that and for vacuum leaks, make sure tps is good sometime it will test good when testing and go bad when it wants, you could have a bad tps and idle air control valve also.11_27_2011_9_27_54_pm.jpg

Idle goes steadily down when stopped for awhile

Idle is bad


did you check to see if your intake gasket is properly seated, and also what kind of idleing is it...if it seems its not getting enough gas check the idle control mod. or do a good clean on your injectors.
