SOURCE: 98 Isuzu Trooper stalls on cold start, idle issues..

I had the same issue on my 99 Trooper.

It would usually start when completely cold, but idle around 2k RPM.
It would drive fine. But if I shut it down, ran into a store, and came back out, it would start but immediately idle.
Had to ride the gas a little to get it into gear.
The Check Engine light has been going on and off for 6 months or so.

I took this to my local trusted repair shop (no Isuzu dealers within 200 miles).
The diagnosed the light, and found that the Intake Gaskets were bad or leaking.
The idling problem was related to the car not being able to control the amount of air coming in.

They replaced the Intake gaskets by the next day, and I haven't had a problem since. And no more check engine light, which has been on half a year.

Here's some details from my bill:
(1) Intake Gasket set $107.95
Misc materials $21.00
2.1 hours of Labor

The total cost to me was $345.00, and I definately don't feel gipped.

SOURCE: cold starts ok warms up shakes and stalls

check engine coolant temperature when it gets warmer, or at operating temperature, and verify that the temperature gauge is showing warmed up to operating temperature. If the coolant temperature sensor tells the computer the engine is cold it will over fuel and miss and the engine will die. When cooled down it will run fine until it warms up. Also could be coil if it starts missing after warmed up.

SOURCE: Engine speed hunts on idle. Auto trans slow shift.

The fast idle valve is inside the throttle body. Sometimes it backs out and needs turned back in (it's threaded). This will cause the loping idle.

Get transmission filter changed with new fluid. Honda does not recommend transmission flushing.

SOURCE: car cutting out from cold start

You need a 10 mil and 8 mil spanner, carb cleaner and mabie some wd40.
Remove the big hose which goes from the throttle body to the air filter housing. Under the throttle body there is a idle control valve, unplug it, spray some wd40 on the 8mil bolts and take them off. Clean the idle control valve and housing and anywhere else which looks dirty, dry it with a lint free cloth and then put everything back on.
remove the battery negative terminal and leave it off for 30 minutes, this will reset the ecu to factory settings.

On the top of the throttle body there is a black circular rubber screw cover, take that off and there should be a plastic screw.

Connect your battery and start your engine, unscrew the idle speed control (plastic screw) so it revs at 2000rpm cold. When the temp needle reached the middle so it revs at 1000rpm hot.

This should solve the problem, if you drive around and find that you in 4th gear, with your foot off the accelerator and the idle is going up and down madly then the idle control valve is worn out and it needs replacing. Cost around £125 on ebay.

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

Rough idle when cold


This could possibly be a faulty engine coolant temperature sensor. these sensors are prone to failing.

2003 Kia Sedona charging system


This is typical. When cold starting/running, it takes more amps to run. It is using amps for higher idle to warm up engine, Altenator is spinning faster, and all sensors are being used at same time.
This is why mechanics say wait til normal operating temperature before any testing is done.
Once the engine hits normal temp, the computer readjust voltage amps, fuel pressure, air intake, timing and more.
