Not posting engine option, makes all answers, weak. all !!!
EFI system , control idle at all times. and hot it very tight 800 RPM
at all times.
there are 2 reason. (and lots of causes. over 50)
1: idle controls are dead. test them.
2: engine AFR is way lean, misfiring (bogging) or too rich misfiring .

on our USA cars, we check (SCAN IT) to see if closed loop status
happens at idle. if it dont we fix that FIRST.
if it is , then we fix ISC/IAC>

the ISC can lose control if it sticks or there are air leaks to the intake system

the first test is always to scan it , ill assume the 60,000 mile tuneup
was already done. after all why expect a bad running engine to idle correctly?

SOURCE: 1999 isuzu rodeo LS: Revs high sometimes then revs

Do you have a check engine light? Which engine? My 1996 Trooper with a 3.2 D.O.H.C. is awful for plugging up the E.G.R. I have cleaned it several times! Good Luck!

SOURCE: surging and dropping idle

It could be an o2 sensor. When you are unplugging your battery it causes it to rereset and loose its memory. If the o2 sensor is going out it can cause false readings leading the problems you stated. You can take it and get it scanned you can do what I did and go ahead and replace all my o2 sensors. I figured since one when out, the rest wouldn't be far behind.

Replaced fuel pump but still revs up the engine and shuts off?


There is gas, the starter is fine, the battery is good. It doesn't matter what temperature the engine is or how long between starts but if I rev up the engine while cranking it starts okay. Rarely I have to rev at stops or the idle drops too low and stalls. If I punch the gas very quickly it revs and drops quickly and then stalls. Starting has a success rate of about 50% without revving. If it stalls, I must rev the engine to start.

mileage comp. like mine, it's useless. forget that. but dead battery reset that, and is of no matter.
questions are plenty on all cases: (cars are complex!)

when you do that the PCM adds more air via the ISC idle speed control valve. and just my do that. and is good sign.

  1. besides stalling, does engine and trans work great , driving, like fast /slow, , hot/cold engine, , up hills too, fast?
  2. is the CEL lamp in dash on key on and off running.?
  3. did you check all fuses.
  4. what is miles on engine.
  5. when did it run perfect last, 1 week ago, 1year, 10 years?
  6. ever get and engine tune up this decade? spark parts and filters?
  7. is the ASD relay dropping out just before the stall>?
  8. is engine rpm below 800 RPM before the stall? hot engine.
  9. does engine reach and old full engine temp, 180F or more?
  10. use a scan tool and see all DTC errors yet, dont skip this.

Stalls when slowing down nuder fifty only once its warmed up


Hi, I am guessing this is petrol engine: in which case you need to remove & clean all the jets inside the carburetter.
If it is Diesel one of the injectors is faulty & needs replacing. Please leave me feed back: Malcolm Campbell, Thanks.

1995 Grand Prix se 3.1L V6 rpms rev up high in park


Does the engine slow down in drive, or is it still running fast and trying to pull away from a stop ?
The problem could be a vac leak, or a sticking idle control valve.
The computer controls idle speed by how much air enters thru the control valve.
