I have a 99 civic 4 door and the engine surges at idle


hot engine or cold, or both???????????????????
surging or hunting idle is complex but for sure the ECU has lost control of idle speed , there are 2 macro reasons, (vast causes)
1: ISC is stuck (in non SAE terms, the idle speed control valve ) is stuck.
2: engine is missing cause the ISC to GO NUTS trying to control
idle and can not.. the 50 reasons, , have list ask.
we do tests to find out if either or both the above are bad.
do you want tests, or guessing>???

97 3.9 dakota when it's cold outside and I start my truck it'll start right up but idle down til it quits . Start it again and it will idle.. Go down the road and it misses bad until it warms up. After it...


Here are the most common causes of idle surge, rough idle esp when cold and stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), 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 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'm having a problem with fast idle and surging on a '92 Toyota Paseo, MT. I have found the two lines broken off the BVSV, could this be causing the high idle/surging?


If BVSV is to do with the brake vacuum servo unit, then yes, it could easily be the cause of the high idle speed. This will cause the engine to run lean too, and admit dust and particles into your engine.

'98 S10 4 cyl. 5 speed: Sudden high idle, now surges.


Go to your local shucks or auto zone and they can check any codes behind your check engine light and it's free. It sounds like one of two things a O2 sensor or your mass airflow sensor but they will tell you for sure

1989 EscortTac shows surges in RPM, but engine does not race up.


How many miles, has the timing belt ever been changed? (60,000-70,000 miles) when the belt gets near or over it's recommended change mileage it will get loose and cause the engine to run like it has a miss, mostly when cold, also u may need to do the following procedure, Escorts need this more than most other Ford cars
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.
