Cleaning Intake & Injectors
 

This is 'similar' to the way we do it in the shop. (we use a professional apperatus to feed the cleaner into the engine while we go do something else). We charge $129.95 for this service. Our cleaners are 10x stronger than what you can buy. But the following method will work for you.

Get 2-3 bottles of Lucas or Techron Injector Cleaner. Use one large bottle (like 12-16oz) per tank. Add to 2-3 tanks in a row.

This will clean the fuel system, injectors, intake valves, combustion chamber, and piston tops.

To much at once (more than 1 bottle per tank) may cause you driving problems by causing possible misfiring.

Also get a spray can of carb cleaner. Chemtool B12 is very good, but any will do.

Next you will clean the air intake system by removing a vacuum line off the throttlebody (like to the VSV for the charcoal canister), and while holding the rpm at 2000-2500, spray "carb cleaner" into the vacuum port.

The engine may stumble some, but continue until 1/2 the can is used.

Stop spraying and shut key off.

On an N/A model, remove coil wire from distributor cap and ground it, or unplug coil power connector.

On the turbo model, unplug the power connectors to the coil packs .

Have a friend crank the motor for a few seconds while you spray the other half of the carb cleaner into the intake thru the same vacuum port while holding the throttle wide open.

This will soak the intake, valves and pistons.

Let it sit for about 30 min. Hook coils/connectors back up. Then fire it up, and blow it out a few times till it idles good.

If it does not idle well, or mifires, you will need to replace, or clean the spark plugs, as one or two may be a bit carboned up now.

This really works?!

Yep. You could remove the 3" intake hose at the throttle body to do the 'engine off & cranking" spray portion of the process.

my car runs great right now, but i figure it couldnt hurt to clean things every once in awhile :) so i'll probably end up doing this, this weekend. Now im going to ask a really dumb question, I see everyone using " N/A " what 'exactly' does that mean, i kinda figured it meant non turbo, by the way everyone uses it, does it mean like Turbo: not applicable? and do you think there is a harm to do this process if there is nothing wrong with the car... kinda like that saying dont fix something that is not broken?

N/A= Naturally Aspired Engine ( No Forced induction)

no forced induction, meaning no turbo forcing air in?.... thanks man.

Yes, Turbo or Supercharger.
