Question about 1991 Dodge Dakota

Intermittent high idle, any ideas?

After changing the plugs the truck idles high more often than not. All vacuum hoses are connected. I notice that the solenoid that controls the idle don't completely go to home position creating high idle. I dont know if the solenoid is the problem or something else.

Thanks for any help

Try cleaning the idle speed control motor with carb spray, it may just have sludge in it causing it to stick, have a dakota myself and had a similiar issue, cleaned the motor and all was well.

I have a 2003 Ford Crown Victoria & it's idled up high. A MECHANIC said that I need to replace the idle sensor. Wat should I do to save money


You can remove the iac sensor and clean the pintle and seat and reinstall, also clean the throttlebody plate. Check for vacuum leaks at the manifold. Try moving moving the idle air control sensor pintle out to (iac) contact the seat to close the idle gap. Reinstall and dont plug it in to the harness. See if it idles correctly, if your high idle is gone then, there is probably a dead spot in that sensor. If the idle stays high you will need a vacuum gauge to connect to the engine a get a reading to check engine idle vacuum, whic should be 15 to 21. Anything lower indicates a leak from intake areas such as injector o-rings bad vacuum tubes or hoses. Always prove things before replacing parts. Good luck

My 66 mustang lopes up and down, I have to crank


high idle can be associated from a vacuum leak in the system- brake booster hose loose---vent hose cracked /broken or not connected. Check for broken gasket from manifold to carby. Check that the vacuum hose for the distributor is connected and not cracked

Idle is rough


Spark Plugs have to be changed every 3 years
Front Oxygen Sensors changed every 100,000 miles
Can't have any Vacuum Leaks -- anywhere on the vehicle
Need to have it road tested with a Professional Scan Tool
& look at all data & get caught up on Preventative Maintenance
Very few people change motor oil 3 or 4 times a year, if at all,
and the Variable Cam Actuators fail, as a result,that & few other
things can cause rough running engine & resulting idle issues
It's well known that Ford COP Ignition Coils fail sometime in
every year of ownership

1994 mustang humming noise coming from intake


Check the vacuum hoses for leaks. Follow them around and make sure they're all connected and not worn out to where they had fallen off due to the hoses being old and worn out. Take some soapy water in a spray bottle and spray mist the intake and see if the idle changes. Check the big hose coming from the brake booster to the intake and make sure it's connected and in good shape. Basically check everything for vacuum leaks. It sounds like that's what you're issue is.

My 1992 toyota v6 pickup is idle high 1200 1500 rpms just had intake gaskit fixed


this is usually a sign of a vacuum leak, if they took the intake off they probably had to take off more than 1 vacuum hose, make sure all the hoses on the intake are in good shape and connected tightly, a good way to find a vacuum leak is to take a can of brake cleaner and just spray the hoses (1 by 1 preferably) as you spray the hoses see if you notice the engine either idle higher or lower, if this happens while your spraying a hose this will be the hose with the leak

DID YOU REMOVE ANY VACUUM LINES OR ANY THING NEAR THE THROTTLE LINKAGE AREA.OR DID YOU REMOVE ACCELERATOR LINKAGE MISROUTE IT CAUSE BINDING OR PULLING ON CABLE THIS WILL MAKE VECHICLE IDLE HIGH.

95 chevy g20 idles too high, how do I turn idle down?


i would first check for a vacuum leak because this is considered a newer vehicle and does not have an idle screw, so I would get some "brake kleen" and mist it at each vacuum hose, if the idle changes then change that hose it means there is a leak, and that should sove your problem, if it doesnt , I would then check /replace the idle air control valve as this is the motor that controls the idle
