Does anyone have a clue to why this is happening:


When 1/4-1/3 throttle: runs great and pulls nice.

When 1/2-Full throttle: White smoke fluttering and no acceleration.

Ive tried all of the ignition Cap Rotor wires plugs and checked the timing. Anyone have any ideas (Except Mark Ive already used up my questions for him this month!)

Thanks inadvance

White smoke is not good.... Has this always happened? You havent turned up the boost already have you?

 

No I kept stock boost. I checked the codes on the car and they read 21 and 22 which are O2 and H2o sensor. Its not a headgasket because today for a short while it ran perfect. I cannot see the white smoke you can only see it when I hit full boost standing behind the car

Al- Hopefully Ill have it fixed by the meet I really want to go and hopefully youll have your ride there too!

 

yea do that
also run a compression test. check your compression and if its low do this. Take out your spark plugs and drop a few drops of oil in the cylinder and if your compression goes up then your rings are fried but if your compression doesnt change then your intake valves are leaking oil into your cylinders--this is how you will know whats causing the white smoke

 

If teh compression goes up your rings are fried? What the hell are you talking about... How are you supposed to check compression if it does not go up? Oh if you have 0psi compression your motor is all good... Austin since your motor is somewhat old your comp should be range from 150-170 psi with the motor warm and the TB completely open when doing the test. I will help you do it or guide you along the way by phone. Its any easy procedure but you must make sure your motor is warm first otherwise the test will be irrelevant. Also remember when doing this test you remove the 15AMP EFI fuse from your engine fuse box. This will prevent any fuel to be sprayed in the cylinders while cranking.

 

yea duh what do you know aout cars then?
the oil drops will seal the fried rings for a few turns causing the psi to go up.....duh! thats compresion test 101

 

So your telling me that if my compression goes up while doing a comp check I have fried rings? What the fuck are you smoking? Oh yeah I know jack about mr2s as well....

 

ok
let say your rings are fried and your compression test is at 150psi. now you put a few drops of oil in your cylinder. this oil seals off the cracks in the rings. now run a compression test again and the compression will go up because the oil sealed off the rings.
dude i dont care if you know about mr2s
thats like the basic shit of n e car.

 

When your rings are fried in an 8.8 comp ratio car you arent going to see 150psi.
