    I have the same running problem on my Grand Vitara V6, they say its a throtle housing problem but I am worried that it may not cure the problem and it is an expensive part

    I have the same problem. Had an intermitent , slight flat spot then the other day I started the car and it is low on power. The engine light is not coming on. I checked the fuel pressure and it is good, put new plugs in. I have read about other's with the same fault but no one has posted a solution. Have you fixed yours yet?

No power when going up hill could be a plugged catalytic converter or fuel filter. A bad ignition control module will act up when the engine gets hot and not energize the coils so they can provide spark to the spark plugs. There could also be a bad coil. The ticking could be a bad coil or spark plug wire that is shorting and arcing. If you take a spray bottle with some water and lightly mist the coils and spark plug wires with the engine running in the dark (outside at night) you will see the arcing. Autozone will test your ignition control module and coils for free.

Why does my 2006 suzuki escudo idle too high once the engine has warmed up, almost like the automatic choke is jammed on but revs are higher than when choke is on

first off no 2006 has choke, i now you are not here, in uSA.
this engine, no size stated or name.
IS this the G16 engine, post a photo of engine,, and we can tell you, every time.
here are the engines used on all 2nd gen Escudo's

1.6 L G16B I4 (petrol)
2.0 L J20A I4 (petrol)
2.5 L H25A V6 (petrol)
2.0 L RF/RFM I4 (diesel)
2.0 L RHW/RHZ I4 (diesel))

the g16 never races, if there are vacuum leaks.
it stalls. or low RPM
high RPM on this G16 is caused by ISC failures.
we clean them every 60k miles, like the book asks.
this engine has EFI , electronic fuel injection and has 16valve head, and the fuel is metered via a MAF sensor.
the ECU controls hot idle all them time
there is a cold start air valve, called IAC,
this is pure thermal device below the throttle body.
and can stick open ,
or the engine does not reach 180f the ISC will no close
even a newone will not close until 150f is crossed !
also not getting coolant changes, the water line to the IAC valve will clog and make it fail, clean that clog and it now works
also the TV can gunk up

see that throttle body , inside is the TV, the throttle valve
it can do this.

this G16 site covers all failures

gunk 101 clean it, or the TV sticks open

Suzuki grand vitara 2001 V6 2.5 litre. how hard to change valve cover gaskets & front engine oil seal, do I have to take out radiator etc

why not just do it one at a time., why make it hard.?
the front cover off is big job.
my guess is you have oil leaks, that it?
the steps are in the FSM book,
you can read them at or at the official suz page.
posted 100 times.

$4 to look.......

or see all parts here for free.
it should be obvious what needs doing, if you look at what is in the way.

non are easy on the v6
you can see the intake is in the way.
and lots more on front cover....
id do the VC first. see if the leaks stops.
or better.
why not use the UV dye, check and find true place of leak first.
then do all that labor to fix. it.

the front cover.
well you can see all thing must come off front of engine, to get
the cover clear of the crank shaft. its clear that !
and how to do that depends on what stops you doing that.
the RAD sure. id have it out already. (not A/C condensor)

posted many times before. but one more time...
in FSM book.
  1. Disconnect the negative battery cable.
  2. Remove throttle body and intake manifold.
  3. Remove ignition coil covers.
  4. Remove camshaft covers.
  5. Clean sealing surfaces on cylinder heads and covers.
  6. Remove oil, old sealant, and dust from sealing surfaces. After cleaning, apply sealant A to cylinder heads sealing surface area as shown in figure.

so you read the book and get to line 2 and see links to those pages.
and ask who do to that, (TB should be obvious)
and that page on intake states

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Relieve the fuel system pressure.
  3. Drain the cooling system.
  4. Remove or disconnect the following:
    • Negative battery cable
    • Strut tower bar
    • Intake Air Temperature (IAT) sensor connector
    • Surge tank cover
    • Air intake assembly
    • Accelerator cable
    • Transmission cable, if equipped
    • Throttle body coolant hoses
    • Fuel injector connectors
    • Throttle Position (TP) sensor connector
    • Mass Air Flow (MAF) sensor connector
    • Idle Air Control (IAC) valve connector
    • Intake manifold ground cables
    • Brake booster vacuum hose
    • Evaporative Emissions (EVAP) canister purge valve connector and hoses
    • Exhaust Gas Recirculation (EGR) valve connector
    • Positive Crankcase Ventilation (PCV) valve and hose
    • Heater hoses
    • EGR pipe
    • Fuel lines
    • Throttle body and intake collector
    • Intake manifold
  5. .... stop,....... im sure it's info overload time.. RTM?

im sure you dont like this answer , and will drive with leaks.
like me....

why not read the manual first then ask questions. not clear.

Machine is throwing a MAF sensor i am told my doesnot have one, doing research on my own. the symptoms match a throttle position sensor.

the grand vitara maf sensor is usually located in the intake air duct, from air filter to throttle body. mounted on the intake manifold. some maf sensors are mounted directly to throttle body. symtoms of a bad tps are---it will cause tranny shift issues, bucking, jerking, idle surging, engine cut off, hesitation on take off, surge while cruising down highway. have a good day !!

Do i need lock tool to change cam belt on a 03 grand vitara

I'd be first confirming whether you have a 1.6 litre Grand Vitara (petrol), or a 2 litre turbo diesel. The 2 litre petrol (straight 4 or V6) or 2.5 litre petrol engines are all chain drive.
If your engine is petrol then no lock tool is required (to hold the camshaft). Of course, there is a specific position that an engine should be rotated too before removing the belt from ANY engine.
If it's diesel, then although I'm unfamilar with that particular engine, the general requirement for diesel engines with high pressure injection pumps is "yes, you require a lock tool" to hold the injection pump pulley. As I think these are a common rail set-up, this requirement may not be necessary. Check with your Suzuki Dealer, or maybe someone else here will know more. A similar question may have already been asked and answered here too.

Suzuki Vitara V6, MAF sensor, white smoke.

My first thoughts are that you have a head gasket or intake manifold gasket failure. This is why you have the white smoke. If you run it too long, your catalytic converter will be destroyed. Check for coolant in your oil too.

Car repair manual for a 1997 suzuki vitara v6 2ltr petrol 24v

Haynes don't cover that engine. I've found a copy of the H25 engine manual which is similar to the H20 engine we have. If you search for SQ416 in google you'll find a copy you can buy or if you're lucky you'll find a free download somewhere like I did!! :-) It has helped me loads.

I suggest either a "Haynes" or "Chilton" repair manual. They are both very informative concerning complete engine tear down.
