Hi, I recently bought a Solus Pro for a good deal to diagnose issues on cars I maintain. I haven't had much or any really experience with scanners besides a code reader. I read over the manual and I understand how to use the unit I just am having trouble understanding what the numbers all mean. Being a 92 I am limited to the tests available, when I was diagnosing some codes on my wife's 07 Nissan Frontier I was able to to a ton more tests fright from the scanner which made finding a COP on Cylinder 1 bad super easy. Apart from running KOEO and KOER tests which test fine and have no codes to show. Do I am needing to understand the data I am seeing to fix what is needed. I don't like throwing parts at a car to diagnose it as that's expensive, so I invested in a scanner to help with this.
If you care to read on, I have a 92 Ford Ranger 4.0 that this year is having issues passing smog. I replaced plugs, wires, idle air valve, cleaned MAF and throttle body, PCV valve isnt stuck and rattles fine, and I am still having trouble passing smog. I saved a movie file at idle (warmed up) and at 2,500 rpm but I don't know what or where to ask for help to figure out what area I need to look at. I am failing HC at idle, the rest of the tests are a pass, there is just to much unburned fuel. I sprayed around with carb cleaner for vacuum leaks but no real dead giveaway. Truck idles a little rough but not like a miss. I ran different fuel system cleaners as well as the "guarantee to pass" stuff but no luck. My truck has always passed smog with flying colors but this year something is not right. Smog guy said the cat is operating fine, as I thought maybe the cat was bad. Fuel pressure I checked and was in spec. No codes were present before this smog test or are now. I replaced the plug and wires because the first time I went to smog the guy did a pretest and the HC numbers were way high even at 2500 rpm. He suggested plugs and wires which I did and changed things significantly and he thought it would pass which it did on every other test but not on the idle. Max was 120 and I am 135. I am still to high. Smog guy said check for vac leaks which I have done already with no idle change. Here are my smog results
Idle-773RPM %C02= 14.7.....%02=0.4.....HCPPM= 135 and MAX is 120..... C0%= 0.05 and MAX is 1.00
2383-RPM %C02=15.1.....%02=0.1.....HCPPM= 40 and MAX is 180...... C0%=0.14 and MAX is 1.00
So I am hoping someone can point me to the right place to ask these questions. I realize this forum is for help with the actual unit, but hopefully someone can point me where to get help. I have a couple files saved on my Solus pro that I can upload as well.
Thanks for all your help!
