Suzuki Vitara V6, MAF sensor, white smoke.

A/t 96 vit. hot and gold engine;/trans both?
slow upshift.
the most common is this.:

1. TV cable to box is jammed at any point of cable or kinked.
2. low pump pressure in the box or filter in box pan clogged.
3. scanning the TCM shows errors ignored? oops
4. the OD lamp flashing odd , means TCM errors. so get them.
5. normal is the shift lever, rocker switch (?N?P?) normal or power shift mode, power shift mode delays shifts for sure. so switch it back.
6. internal transmission leaks can cause #2
7. low (super) low tranny ATF (done hot,in park and engine running never overfill any box or use the wrong ATF. ask. first or read the glove box guide (IIRC,Dexron 3 to max #). RTM manual,
8. if TCM sees speed error from speed sensors ,the VSS sensor at rear of tranny reads slow, the shifts will be late. speedsensors

run the fault codes.problems may be from faulty sensors in the exhaust system, low fuel pressure, venting problems in the tank,loose connections to the ECM or MAP/MAF/VAF sensor problems

When starting/cranking, computer will activate fuel relay so that it will start. Once running there are fail safes built in - no oil pressure, bad signal from crank angle sensor or throttle position sensor, crash sensor activated (stops fuel pump) or even immobilizer faulty. Will it idle with Mass Air Flow sensor unplugged? Could be a broken wire or bad connector. Hope you have found problem by now! An auto electrician will find it very quickly.

Relaced all that and didn't check the catalitic converter. When you get codes for MAF sensor and 02 Sensors, the first place to check is vacuum leaks, if none are found then it would go right to the catalitic converter. You might want to consider another mechanic.

Hello and welcome to FixYa!

If the check engine light is on then there's definitely a problem. The engine rpm is erratic right? This can be caused by a faulty MAF (mass air flow) sensor. If the MAF sensor is faulty the idle will surely be erratic and may cause stalling.

You will need to have it replaced to make the vehicle back to it's normal operation again.

Hope this helps and thank you for using FixYa! Have a good one!

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 !!

gap is 0.039-0.043 [in] ngk bkr6e-11

disconnect carter-gases pipe(over the ref-pos sensor), and if smoke stops, You don't need new engine :)

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.

The MAF has been a source of trouble for Audi such that the cost of replacement was halved a few years ago.

I am not sure why replacing the MAF would produce white smoke - white smoke being symptomatic of steam from water or coolant ingress into the cylinders or extreme amounts of fuel entering the cylinders. The latter is almost exclusively a diesel problem.

Generally if the MAF is suspected of being the cause of rough running then disconnecting it will cause the engine management to switch to the get-you-home programme. If the engine runs better the MAF is probably faulty..

As a matter of interest, it is necessary when changing parts on Audi that only the correct parts are used. Not only must they look right and be intended for that year and model but the part numbers should also be correct. A couple of digits out isn't close enough...

I am not sure where the idle thingy is on your Audi - the earlier models used a throttle body with the idle/throttle sensor and idle control all integrated in one very expensive lump and that is how I discovered the importance of correct part numbers.
In order to save my customer from scrapping what was otherwise a good car, I took a can-opener to the throttle body and opened it and found two broken wires and mananged to repair them. I needed to do some tricky welding to put it back together. The car went on for another seven years afterwards...

The car made no white smoke prior to the repair but the idle was very erratic...
