SOURCE: My 1994 Ford Thunderbird now smokes when I start it - no noises in the engine, but smokes like crazy. Check engine light is one now?

state what color the smoke is. White smoke is antifreeze. Gray smoke is fuel, and black smoke is oil. Also have the computer scanned so you know why the light is on.

check your throttle body make sure all the springs are connected. your throttle body may be nasty inside and may need cleaning, it may be getting stuck. Throttle cable could be sticking or disconnected (there are two one pulls and one returns to idle IIRC)

also you should really search and become a member there if you are not already.

OK, so is it still setting the codes? Or has that gone away with the transmission harness repair? The idle is controlled by the Idle Air Control (IAC) solenoid. Ford has had a lot of trouble with these. However, the symptom is usually low idle speeds that cause the engine to stall. I think I would be looking for vacuum leaks. Ford 4.6L engines are notorious for the PCV hoses leaking at the elbow where it connects to the back of the throttle body.

High range 4x4 works. light comes on. but the low range does not ingage nor does the light

dunno if this is your solution but your bronco only will go in low range if it is in nuetral. not park but nuetral only start your bronco put it in 4 high first then once it goes into 4 high make sure in nuetral then put in 4 low.

Idles too high.

most likely a sticking idle air control motor.It is the round log solenoid bolted on the side of the throttle body. Try tapping it with a hammer first to see if this un-sticks it. If so this is your problem and replace it.

High idle when in drive

Sounds like a faulty TPS sensor, also could be the ECM playing games with you,,,try disconnecting the battery for about 20 mins,,then reconnect,,it may clear it up.

Car 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 (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) 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.
