After I Buy 3M 08963 Fuel System Tune-Up KitI purchased this product from amazon for $36 minus the $10 rebate, $26
In general this is a GOOD product. I used this product on a 2001 Acura 3.2cl with about 115k miles on it. Overall, my car did see a slight improvement. Upon inspecting my throttle body it was evident that the intake system was fairly clean, the throttle plate was showing brass color upon beginning. Even though my car was clean to start, there was a noted improvement in the initial startup and idle.
My vehicle used to suffer from a slightly sticky throttle plate and as a result the first time it turns over usually had a bit too much gas, I could feel the engine moving on the motor mounts. Now when I start up the car, the initial turn over is smooth as the pressure required to open the throttle plate is less.
Pros: Cheap, easy to use, does what its supposed to!
Cons: The instructions for this product are really bad. Mine did NOT come with the DVD as it was supposed to. Luckily I watched it on amazon, its posted on the product page. Please note: the DVD is pretty much useless anyway, there is a much better way to do the cleaning, read "other thoughts". I minused ONE star for the missing DVD.
Other thoughts: I found many of the customer reviews to be very helpful!
1) Be aware, many newer vehicles have plastic covers on the engine, most require METRIC ratchet sets to remove, I had to buy a set for about $20. In most cases you cannot reach the throttle body until you remove the covers!
2) Prior to doing Step 1; Park your car at an angle where your throttle body opening is facing slightly downward. You can do this by placing the car on a curb, or slanted driveway. This is really important, the first spray sends a very slight, yet consistent fluid down your intake for about 15 minutes. If parked at an angle, the remaining fluid will biuld up (along with all the carbon) behind the throttle plate and you can easily wipe it all out in step 3. Once you open the throttle body, gravity does most of the work for you, it just pours out, be ready to catch it!
3) DO NOT SPRAY THE THROTTLE BODY CLEANER INTO THE THROTTLE BODY UNLSS YOU WANT A ROUGH RESTART. Instead, spray the cleaner directly onto a microcloth, then stick the cloth into the throttle body and wipe. DUH! I used 3 cloths. Alot of carbon came out. I DID NOT SPRAY THE CLEANER INTO THE THROTTLE BODY, PERIOD.
My car started up perfectly, NO hesitation, NO smoke from the exhaust. NO PROBLEMS WHATSOEVER. I did not notice power gains, however my car is smoother. It feels like I just had a tune up. When your engine runs a bit closer to OEM spec every other component in the vehicle just syncs up better.
All in all, worth way more than $26.
