Question about 2001 Mitsubishi Montero

2 Answers

Have a 4M41 engine in the 2007 mitsubishi triton and when under acceleration between 2000 - 2600 rpm the engine hunts or surges and then clears after 2600 rpm. It is more noticeable in 3/4/5 gears only because it spends more time between the rev range, what could be the cause ?

I had a similar "hesitation" on my 4m40 engine and found it to be resolved when I changed my fuel filter. Gained power and slight economy as well.

It needs a programming check of the accelerator pedal via ecu of the engine. All previous activity of the system is recorded in the ecu which can be corrected in the dealership of mitsubishi.

2000 Suzuki Esteem 1.8L.. I went to start my motor & turned it off right before started. I heard some kind of backfire. Then I started it and it's been idling high, the surging. Please help!!


scan it yet, a FULL OBD2 scan? why not?if not.
now is the time...


the 1.8L J18 engine, same as the older Sidekick sports used.
same engine , know it I do.
its the precursor to the J20, (j18 is under-stroked, j20 with many of the same parts. inside)
the back fire means explosion sound to rear end of tail pipe?
yes, that is rich raw fuel in the muffler. plus Air.
if there are exhaust cracks and then engine goes rich this can happen( a double failure)
if how ever BACK means, back to the Air cleaner, then that be different reasons, (timing)


engine now starts.?>
engine runs.? has full power, car drives ok.?
JUST?
SURGE,. you never said.

does engine get hot? 180F or more and holds (y/n)
ever get a full tuneup this decade,
most dont so i tell you, bad spark causes, misfire and raw fuel is wasted to the exhaust and sure can go boom.

surging usually means the ISC can not control idle
so it hunts, (a suzuki software engine on all 90s engines)
PCM errors, inside it. (dangerous too)
a modern car, if idle goes too high the ecu commands the ISC closed
and holds it there solid, (safe way , no hunting allowed now)]
so if this car surges, it's , lean engine.

some think flooding is surging.
and this is usually below 800 rpm,
almost stalls, then corrects, seems like a surge.

next time post rpm range of surge.?????

do not drive a surging engine, do not be like Toyota drivers. (over 800 rpm hot)

surge from 400 -800 rpm is class 1 surge.
surge from 800 to say 2000 RPM is class2, and very dangerous to some folks, (key off, get car fixed, tow it)

The ECU controls idle speeds. (hard coded servo controls)

Depends on how good the mechanic is. Dealers have a book that sets the time the job usually takes and will only pay the mechanic that amount of time. If he gets it done faster good for him, he gets a bonus. If he takes too long then he only gets the book time.

check for a vaccuum leak this is where i would start if it rolled into my shop. possibly a PCV valve sticking or a hole in the hose, this hose should run from the valve cover, or crank case and then to the intake, or carb.
