Yep,pretty normal ,the idle air control is either really
dirty or bad,I'm thinking just dirty because it works when
first started. Just unplug the wire ,take the 2 screws out and clean
it with injector cleaner.(round cylinder,about 3 inches long)
Also pull the air cleaner tubes and clean the throttle blades as well.

SOURCE: high idle problem.unpluged map&cold start

on newer trucks what might happen is the choke gets stuck making it idle high. start your truck and tap the gas a few times and see if it doesn't lower the idle. if so you need to clean the mechanisam so it will not stick again.

SOURCE: truck starts, dies. truck runs good some days,bad the next

I had the same problem with My 1990 F150 300 6cylinder 4x4.....I cahnged all the same things you did, finally I sprayed a can of Gumout through the throttle body and it worked and ran great. Now I add fuel injector cleaner to the gas and a regular clean with the gumout and the problem has'nt come back. Good Luck to you and hope it works!

SOURCE: truck runs rough

Sounds like one of your chambers isn't firing. Run your car for a few minutes, shut it off then pull your plugs one at a time and see if one of them is wet. Might just need a new plug.

Check for a stopped up fuel filter or clogged catalytic converter. Either one can cause the car to run this way.

Sometimes to start you have to give it a lot of


Hi
This sounds like a cold start system fault, which is a number of things.
  1. Cold start temperature sensor not operating correctly so the cold start system won't work when the engine is cold.
  2. The idle needs to be set to the correct RPM of the engine when warm, if it is idling ok when it is warm then this wont be the problem.
  3. Spark Plugs are worn and need replacing.
Most case's its the cold start system not operating correctly and if you have a good workshop to take it too they should pick this up quite quickly. Hope this helps, let me know how you get on.

89 dodge shadow. hard start. normal idle cold, fast idle warm. sometimes it wont start until i hear fuel pump activate.


Hello,
The car may be hard to start because it may need a normal tune-up. If the spark plugs are pretty used, they will slowly stop burning as much fuel because the spark slowly gets lesser and lesser. On a cold day the fuel is harder to ignite with a small amount of spark.
Normal idle when its cold means that your cars idle is probably too high. If you lower the idle, the choke on a cold day will keep the idle a little higher until the motor warms and then it will kick back off. If the idle is too high, it will run very rich, smothering itself with fuel, and causing the idle to stay low. When the car warms, its creating better spark when its warm, and with the idle being too high its running at a fast idle.
The car wont start sometimes can be the cause of a few things. If the ground is bad on the fuel pump, it wont make a good connection sometimes for when you turn the key on, the fuel pump dont pump the fuel to the engine. Another one can be that your accessory switch can be loose going to the fuel pump. I think its your ground though. Good luck! Hope this helps.
Have a nice day. -Steve

try checkin your idle air control. most of the time it is a vacuumn line going into intake.pull it off and if the car revs up dont worry, it wont hurt it. if it does simply put it back on, if it dies you have a bad vacumn.
