rough idle, stalling, loss of power. - CarGurus

Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue 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

check for your HT-spark leads.

i have the same exact problem, i have replaced fuel injectors, idle position sensor, idle air sensor, map sensor, temperature sensor,. the only way i can make mine run ok. not great is unpluging the map electrical connector, and it still has no power if u gas on it but it makes it down the road and smells rich, if u find out let me know what the problem was i really love my truck and hate that it doesnt run right, [email protected]

Change the temp coolant sensor,and it will change the lean ,rich situation.

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.

There are a few thing I need to know, what engine do you have, how many miles on the van, what part(s) of the test did it fail?
