[T3] ANSWER TO YOUR QUESTIONS ON EFI AND GENERATOR LITE


<x-charset iso-8859-1>Jason,

 I am here always, just reading and hanging , I am not in the military
so I do not deploy on ships but do get sent out when they need my
brains.

The white smoke that you mention, does it have a very lite hint of 
Blue and does this puff stay together or dissipate quickly ? 
If it does(blue and not dissipate quickly) that would be oil passing through
because the 
valve guides are worn to death, too much oil in the crankcase or
your new rings are still settling in, this is the most common
occurance if all of the parts are the correct ones. 

The other thing that maybe happening is that the engine is producing 
steam when cold , my Square and my non VW car do this and the cloud 
is white and dissipates quickly and dissappears and does not 
linger as a pollution cloud does.

Check your spark plus to see if engine is burning oil.

It all depends on your symptoms.

The following is in relation to your inquiry on your smog test ?

Why is it hard to keep your engine at the minimum of 2250 ? 

Before messing with your sensor,  check the following:
(mixture too rich)

- Check compression , too low compression will increase 
CO levels since fuel burn is lessened.

- air temp sensor connected, a disconnected one will either
  make your engine run a little rich or not run at all(depending on
EFI version number), Increasig CO levels.

- Have you checked all of your injector's spray patterns.
You must have a nice conical mist, no peeing, muliple
streaming or gas dumping.

- Are you having vacume leaks ? check all lines, including 
intake manifold rubber boots and throttle body back plate.

- Is your engine capable of very slow idle ? if not , you may have
a vacume leak.

- Is your fuel pressure too high ? If it is, you can have the smog guy 
tweek it down for the best CO level.

- I have found in a  EFI manual that mentions replacing the head
temp senor with a new  leaner different part number one when 
the CO tests fails. There is a trick to simmulate this one with 
a different heat coefficient by placing washers under the heat
temp sensor to increase mixture if it is desireable or placing
a resistor or variable resistor in series or parallel to the head sensor to 
increase or decrease mixture as desired. You can dash mount the varible
resistor 
if desired to fine tune the engine or to pass a CO test. I wish to do this
in
the future, using a dash mounted  mixture ratio meter.

-Is your battery/generator voltage (engine running) between 13.5v
to 14.5v) ? Someone correct me on this. Too low a voltage will 
increase your mixture too high I do not know but if it is too high 
you may have regulator problems. Is your voltage steady and
not erratic at different speeds. If you see problems , replace regulator.
Temporarly install a voltmeter to check this.

Checking all of these will correct your problem. If it is necessary to 
adjust your pressure sensor, let me know and I will email you 
how to do this.

I may have missed some items  that can add to the variables,
another variable are fuels and this we have no control over ,
you can add some of that liquid pass smog test stuff you can get from 
almost any auto parts store. 


The answer to you gen light problem maybe worn generator brushes 
or bad regulator , I have had both of these problems several times.
If you wish to get the new solid state regulator for your car , I have a
local source . These are Mexican Bosch regulators and they hook up the same
way . You may also find this locally. No more burned contacts or
intermittant erronous
'G' light indication. If gen brushes are worn repolace them and inpect the 
generator's copper contacts, I had one that burned lopsided and gave me
hell,
the brushes would noticeable bob up and down, especially at higher speeds,
they would bounce erratically and give me strange symptoms from lighting to 
EFI symptoms.

You say your car has some bucking at 55-65 mph. I have had this with almost 
anything causing this , you think this is caused by the throttle position
switch ?
Ask some more people about this switch, I do not know if the switch may
cause this.

I had this bucking trouble from the following :

-Generator brushes bouncing 

- Loose EFI wires

- Injector wires loose

- Crossfiring in the distributor cap or wires

-Old injectors , (pintle sicking on scuffed guides)

 I may have missed something , Can anyone add to this?


On your rust hole questions , I had my car corroded at the 
back, bottom  and on top of both front fenders also the bottom
front of bot doors had this problem . What  did to permanently fix this is 
to have stainless steel sheetmetal pieces welded or braised using
brass. After this is done had the body work just thinly filled. Rust will
never
happen again there. To remove rust without cutting first clean with wire
brush or
some time of metal gun por pipe brush , then add naval jelly
(home depot)  to this and all of the rust will miraculously mely away and
can be washed 
off.

If you just fill it with a thin layer, using fiberglass or glob it in ,
it will rust againg at the seams because filler is somewhat porous and 
will accumulate humidity. this does not make metal rustproof. If you lightly
fill the holes using bondo, fiberglass and or metal tape, rust proof the
back 
with por 5 stuff you guys always mention or fiber elastic cold roofing
tar/sealant (home depot).
This way your job will also never rust on that side as long
as sealing integrety is kept . The painted side of course is water proofed
and rust 
prooed by paint.  

I hope I anwsered  all of you question s , I hope some people out there can 
add to this or correct my mistakes
