    I did clean out the intake air supply with intake cleaner, then took it for a ride. It still would drop off rpms and die while driving when you left off the gas pedal. Had to keep foot on gas too keep rpms at around 600, cleaned it some more when I got to home again, but it still would not Idle.So later I went out to eat and after driving around 20 miles it started to work ok. BUT I still bought a TPR senser and installed it. So far so good, thanks for all the responses.......Dave

I woulds replace the fuel pump. But before doing that go under the hood and on the right hand side there is a grey back open it up and you will see some plugs, There is a 3 prong plug take it out and replace it, that plug is placed in the front. I would try thats first only because this is lets just call it a battery for the gas pump and is it is not working then the gas pump will not work and you will not has a car. Some times the car will start fine and some times the car will not. So replace the plug before the gas pump. This part costs about $4.00. If for some reason you are not able to fine the box let me know and I will do my best to get you the info you need in order to find it.

Here is the most common cause of surges and stalls, 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.

1997 ford explorer V6. Engine was idling to warm up, went in house for 10 minutes. Came out engine smoking knocking like crazy. Shut off engine and opened hood, oil was sprayed all over engine oil...


this sounds like the engine oil cooler hose was leaking.

DO NOT run the engine again until you fill with oil.

start the engine and look for the hose that is leaking.
