So, I put the 2k2 maf in months ago to replace the 2000MAF sensor. Reset ECU, SES light shut off... Week or two later, light comes on again. Whatever. FAST FOREWARD, few days ago car started running like crap. SES light flashes in serveral occations. Twice during different occations. Taking it seriously, TurboMax95 Helps me pull codes. Heres what i find. During this mess i Re-install the 2000 MAF. So codes are pulled with a 2000 maf.

P0300 Random misfire
P0430 TW Catalyst System, Bank2
P0139 Rear o2S, Bank 1 Response Monitoring

Pending Codes
P1147 Heated o2 Sensor 2
P0102 Maf Sensor (probably 2000 maf caused)
P0113 IAT Sensor (2000 maf dosent have temp sensor)
P0021 Intake Valve Timing Control

White smoke from exhaust, rough idle. Lack of power, sluggish, surges sometimes.

Reinstalled 2k2 maf, RESET ALL CODES

Pulled front plug tip black in color charcoal looking.
Pulled rear plug, great condition very clean.
(NGK irridum)
Pulled rest of front two plugs.
1st one (Passenger side) was totally black as well, oily grit around the tip.
2nd one was black
3rd one was black as well.


Put it all back together and drove car around block, Pulled codes again

P0113 IAT sensor
P0021 Intake Valve Timing Control



Okay, my thoughts. Busted o2 sensor on my front bank causing a super rich conditon (black plugs) . Soloution change all of my o2 sensors. Which should also take care of my mis-fire situation. MAF sensor is fine now. What REALLY bothers me is the Intake Valve Timing Control (intake VTC) not sure whats up with that, but i do remember a TSB on this issue for a 2k2. So the only thing im worried about is the VTC issue, i dont have any knowlege or ideas for that.


As for the white smoke im hoping its caused by a super rich mixutre.

Last issue, Plug 1 front passenger. Had oily residue on it. A leak of some sort? Ive ruled out a blown gasked since my coolant is clean. BUT my oil thats 750 miles old is dirty, with grey residue left on the dipstick.



Whats up with my VTC ?
Whats up with my oily plug, and dirty oil?

This was posted on max-world.org a few days ago, getting o2 sensor changed tommrow on the front back, upstream one. Gonna see how that turns out. In 4 days im going to check compression as i replace the front plugs.

Radiator top is still clean, no foam or evidence or oily residue within it. its still crystal clear green. Radiator Reservoir is still clean as well.

Pulled o2 sensor tonite, its charcoal colored.

Still could be a head gasket problem. Clean/non-bubbly radiator coolant is a plus.

my take is that white smoke is usually the opposite of a very rich condition. It actually happens when you burn oil. I say piston seals, etc

pulled o2...replaced with new one, idles much much better. White smoke still present upon start up and idle.

Rest ECU via procedure at technosquare site. CEL light shut off, white smoke dissapeared from idle. Exhaust smells much better.

Car is sluggish over 3k rpm, light white smoke appears. My guess, the 3 fowled plugs up in the front bank are causing this.

are you runing N2O ? If so, sounds like you fried some piston rings and the engine is burning oil. Another thing might be that the VTC has failed and this will cause low power- reminds me of the VE30DE engine that has all kinds of VTC problems. White smoke is blown head gasket, blueish smoke is oil and black smoke is runing rich.

White smoke can also be from running massively rich...and by massive, I mean to the point where you may only get 150 miles per tank no matter how you drive it.

I once owned a car- 4 cylinder that the MAF was royally messed up on, I would get 100 miles to a tank full of gas vs normal 260-300 depending on how and where was it driven. I never seen a car run pig rich and put out white smoke. Are you sure its not just water vapors like the ones you get on cold morning starts ? What does it smell like ? if it smells sweet then its coolant.

no nitrous, o2 sensor replacement made it run a little better, I'll try the guranteed good 2000 maf again. New plugs are on the way, i'll pull the old black fowled ones, and check compression. Reinstall new plugs, reset SES light again.


Its whitish , present during start up, and at higher 3000k+ rpm. I can see it spewing out the back of the car when i look into my rearview miror. Hopefully nothings fried or blown. Oily looks nasty tho, its gotten to a dull grey color.

Audtatious

Obviously the ignition system is not changing the oils color. The only time I have seen oil change to a grey is when water/coolant are getting into it. The only time I have seen that stinky-sweet white smoke is due to a blown head gasket. The smell and look is a whole lot different than a rich condition or when burning oil.

Run a leakdown test, compression test will not always show a bad head gasket. You might have a cracked head or block. O2 sensor or MAF issue might cause black smoke (excess fuel) but never white smoke.

Well, I should have mentioned that the vehicle I am talking about has no cats, and yes, it smells like fuel (b/c it is)...

If you were to light this vapor, it would seriously blow up. I guess my post has no bearing on his problem b/c he has all his emissions and such (I'm guessing he has at least two cats)...
