Binding throtle linkage or idle control solonoid not working.

With mine it was the IAVC(idle air valve control) on my 94 2.3L Tempo. I got the part used for $10 at junkyard($54 new at Knetch's). On some, the springs stick so you can try spraying it with carb cleaner to loosen them up. Although on mine, the springs moved but you could blow on one end and air came out the other side. On the "new" IAVC part, air wouldn't pass through but fixed the high idle perfectly! Before you take it out, try tapping it with a hammer to see if it temporarily changes the idle any. If so, that is certain to be your culprit for sure! It was mine!
!t can be the air flow censer it might be messed up or the rong one usually the rong one will make it idle high.
whats the problem for my 94 ford van engine high and low idle
a vacuum leak can cause high idle
You can adjust the idle.
because everyone elses 1993 ford tempos stall when they idle. learn to drive with one foot on the gas and one on the brake like I do in my '93 tempo. keep the RPM at 1000 and it won't stall out.
check the EGR valve they are known to be faulty
Check for broken motor mounts.
go to autozone for a free diagnostic check & the computer will tell you what is wrong ie map sensor. idel air control . mass airflow sensor
Try cleaning or replacing the idle air control valve (IAC) located on intake manifold next to EGR valve.
Not really possible. There is an idle speed control on most 1988 v6 machines. If you are experiencing high idle, it may be a broken ISC. The idle speed is controlled by computer. http://www.marksatterfield.com
vacuum leak. check the hoses for cracks in vacuum hoses or intake.
Through the dipstick tube where the indicator inserts. Be sure to have the car warmed up, running at idle, in park when you check the automatic transmission fluid.
There is not a low idle screw. The computer sends a signal to the idle air control motor and it does the adjusting accordingly. If your idle is to high and your check engine light is on then you need to go to a repair shop and have them diagnosis the problem.
How high is your idle? idle should be 800rpm good oil pressure is obtained at this idle
Stuck throttle plate vacuum leak bad TPS I used to drive mine over 500 miles from DC to Columbia SC and it would idle high once I finally stopped. A guy did something to the throttle to loosen it but....the solution is the idle air control valve. Its right in front of the windshield wiper fluid. Its as easy as replacing the TPS which is two bolts holding it on but make sure you get the right TPS and a Motorcraft idle air control with gaskets. If you dont you might have the same issues again. Easy to replace if you have a socket wrench.
There is no idle screw. The idle air control valve controls the idle and can be set on different settings. You should consult a Ford dealer or mechanic for proper settings.
The 1995 Ford Aspire would have a rough idle cut off of power at high speeds due to mis firing. There is also a rev limiter to control how fast you can go.
Idle speed control or Idle air control.
where is the idle control motor for a 1998 ford escort
you have to turn the idle screw down ?? ? ? ? ? ? ? ? ? ? there are 2 of them. one on the right and one on the left. the left one is general idle and the one on the right is for air-conditioning idle and high power output idle ( rev higher ) A vacuum line may have come off if it has started revving.
When you crank it? What are you driving a Model T Ford?
possible cause of high idle could be that your idle contol switch / valve has carbon build up on it. remove and clean with carburetor cleaner. let it dry completely before re-installing it. idle should come down if not it has probably gone bad and need to be replaced.
there is an idle control on these cars, could also be a problem with your intake, and idle. that's what was wrong with my 2000 focus. i lowered the idle, and changed the air filter.
