You need to scan the computer and drive it with a scanner on it. Check for codes and watch the Throttle position sensor readings. It sounds like a problem with the tps or Idle speed motor.

Car dies when engine is put in park. Engine is warm already.


This can be cuased by a sludged up engine throttle valve and automatic idle speed control valve, do the following procedure and this should fix it.

To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

I want to adjust the idle on a 2003 ford f150


The engine Idle is adjusted by the PCM (power control module) If your having idle problem, cleaned the throttle body real good (just to make sure there wasn't a problem there) then do a "IAC relearn" by unhooking the battery, letting it sit for about 5 minutes, then hooked battery back up, let it idle for 3 mins, put in gear and held it there for 3 mins, and then neutral for 3 mins, then back into park. Go for a test drive and this should fix the problem.

When its warmed up, in park or in gear, RPMs are about 600-650 at warm idle. At cold its about 850 or so, Good luck and thank you for using Fixya

1995 Taurus Engine Stalls


Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Transmission??


Have you checked the transmission fluid level? The car should be driven for 20 minutes or more, then with engine running vehicle in park, pull out dipstick, wipe clean, reinsert, check level.
When the car doesn't go anywhere, do you let it idle for 5 mins before you drive? If yes, the fluid level could be low enough that 5 min idling warms it up just enough that the fluid is expanding and slightly raising the level just enough to operate. The fluid on the dipstick should be pink, if it's dark you should have it changed, along w/ the trans filter. Be careful of fast change shops, as some just shove a hose down the dipstick tube and suction some of the fluid out. This is NOT a fluid or filter change, just a small amount of fluid is removed. Hope it's just the fluid level, but keep checking on regular basis, as running w/ low fluid (or overfilled) can ruin a trans. countrycurt0
