Bests & Worsts Reviews from Amazon

After receiving the reader in the mail, I opened it and looked through the booklet. Seemed pretty easy to me. So I plugged it into my car's port, turned the key to the on position without starting the engine. It brought up a code and then identified it as the intake manifold tuning valve. Went to the genuine GM parts store online and ordered the part for my 2008 GMC Acadia. Then went to youtube and watched the valve being changed. Didn't seem to difficult. Once I got the part, I removed the old valve and replaced it with the new one. Took about 20 minutes. Started the car and it ran fine. Placed the ignition in the on position without the engine running, plugged the reader back in, was able to clear the code and engine light was off. Paid $23.85 for the reader, $153 for the part. Since the part listed for $279 that is most likely what the dealer would have charged me for the part, plus, $99 diagnostic fee, plus I'm guessing $150 for labor. Saved myself roughly $350 and I have the reader to use some other time when needed. I love saving money! Thank-you.
