Bests & Worsts Reviews from Amazon

I kept bogging down on my 1998 CR-V. I checked and rechecked timing, fuel pressure, spark plugs, distributor, everything. NO check engine light on, I was going crazy. Finally decided to shell out the money for a "pro" scanner, better than my $20 walmart one. I plugged this one in, took it for a test drive with the data record feature, and guess what I found- a bad O2 upstream sensor. It kept telling my computer it was rich (voltage was .6 to 1.2 all through the ride), and the downstream sensor dipped to near 0 as the computer cut back fuel. My short term fuel trims went down to -30%. All of this and NEVER threw a darn code for me to figure it out. I spent hours upon hours trying to find the mechanical issue, when this electronic tool took care of it in about 15 minutes. A no brainer, your time is worth way more than this costs, buy it. And I'm your average tree shade mechanic who works on his own cars, not a fake reviewer as you can see on my history. This product was that good for me to leave a glowing review
