Mileage ?

2001 civic. I cleaned and oiled the K&N filter and have gotten poor
mileage since then. Is it possible to over oil these and slow down
air flow. I also had to drill out th three front screws that hold
down the air cleaner cover an replaced with nut/flange bolt config and
got the cover secure again, I assume this would not be the problem?

 

it is possible to overoil. oil gets into the throttle boddy and coats
sensors that aren't supposed to be oily. take it out and clean it....
better yet switch back to OEM.

I ran a K&N filter charger on my 98 civic from about 70000kms til now
(285000kms). I don't think its caused any big problems on my car
(compression on my cylinders is all within factory spec), but there are
plenty of studies out there that show a K&N allows more particulate through
which can cause premature wear. I live in a climate that is frozen for
almost 1/2 of the year, so I think that may help in keeping particulate down,
hence why my car shows next to now wear.

the screws are a common problem with this model.

What would be the best way to clean up the throttle body?

You posted this independently to two different groups. Learn how to
crosspost properly.

This is what I said in your other group:

It IS possible to over-oil it and foul the throttle body, the idle air
control valve, the intake air temperature sensor, and the fast idle thermo
valve. These are critical components and are very expensive to replace.

Why on earth would you put such junk on your car in the first place?
Because it looks "kewl"?

Check out this test:

Once you read this, you'll want to hastily retreat to the safety of OEM
parts.

Toothbrush, lint-free rag, throttle body cleaner.

Put brick on gas pedal or something to keep pedal on floor.
Spray cleaner on brush, then scrub all traces of carbon from all surfaces
in throttle body.
Dry off brush. Wrap rag around brush, use that to wipe away scrubbed
carbon. Repeat until shiny clean everywhere.
Do not spray into orifices in throttle body.

Remove brick. Start car.
While car is idling (COLD), spray cleaner into TB orifices in a few short
bursts, allowing the engine time to stumble and recover. Too much may drown
it.

Check for oil in air cleaner hose. If present, spray copious amounts of
cleaner down it to get rid of the oil. Let dry (do not wipe!), reinstall.

Tegger, do you have any experience/opinion re the K44 cleaner? It's
pretty expensive, but I have been told it's the best.

Never heard of that one, but I haven't noticed any difference between any
of the cleaners I have personally used.

It's the brushing and wiping that does the job. The cleaner is just a
solvent that allows the crud to float off, and permits wiping it away.
