Just wondering if anyone else has had their injectors cleaned? I had Jiffy Lube do it at my oil change today, I got a good deal on it due to going synthetic a few changes ago and a slight hook up 'cuz I knew the guy so I said what the hell. They hooked what looked like an IV bottle up to the vaccuume hose and idled some stuff into the motor. A Gas treatment also went in the tank. He reved it up and blew some carbon out of the tail pipe after the IV was empty. I had some rough ideling at first but it seems to have smoothed out after a few miles. Did I get something I didn't need or was this a good thing? I felt an 'awakening' of the motor (I have 68,000 on the odometer) but I guess it could have been my imagination. Anyone else do this procedure and if so what were your results. Thanks -Kevin

 

Chamber cleaning is never bad and neither is injector cleaning. The rough idle and the "awakening" is normal. The rough idle is caused from the residual stuff working it's way out of the combustion chamber. The awakening is from your chambers being "larger"...not really, it's just that the carbon buildup is either skimmed or removed (depends on what they used for how long) from the chambers. MCCC or Seafoam does the same thing and it's a DIY'er. I don't really believe in that "gas treatment" stuff to clean injectors like some state either, I guess I'm just a Seafoam or MCCC guy. If what they put into the gas tank is real, then the injectors will start to unclog within 50-100 miles of driving and that depends on your speed. The highway will net you faster results but then again, if you do a lot of highway driving to begin with...your injectors should be fairly clog-free just from the injectors duty cycle.
Just food for thought.

 

We do that at our shop at Victory Lane. Yes it does work. I have a 2001 Chevy S10 with 68,000 miles and afterwards it starts a lot easier and gets better gas milage with a smidge of performance return. We take the carbon off the throttle plate and the throttle positioning sensor. Smother air flow and a more accurate reading for the computer as far as the throttle body cleaning. The IV drip that goes into the vacuum is for the brake booster. It enters the intake manifold at the throttle body behind the throttle plate, so everything that couldn't be reached by the throttle body cleaning will be cleaned up here. It cleans the carbon off the intake runners, injectors (before it is mixed with fuel), valves, pisotons, catalytic convert, and O2 sensors.

 

How much did this cost you?

 

Don't take it to a stealership if you're worried about cost. I had my hemi in for an fluid change and wanted a bit more than $300 to clean the injectors. I laughed and told them no way.

 

This cleaning cost me fifty bucks. They charged me 92 bucks all together with the 7 QT synthetic oil change. I do do a lot of highway driving, usually I average 80 MPH for the 80 mile round trip to work five days a week. That is probably why I didn't see A LOT of carbon smoke. I have seen way more in the past when I sea foamed a Dodge Conversion Van I used to have, that cloud went down the block and that van was predominately a city vehicle. Thanks for all the input guys, this may even correct my O2 sensor code that the truck threw a few months ago. I am trying to avoid that expensive tune up for a little longer also so this should help hopefully. Thanks again -- Kevin
