Yes, I agree, very informative and designed for someone who does not have access to expensive diagnostic equipment or is a master mechanic. I believe that many people on this or a lot of forums are in this catagory. Good work.
If that would have been your first post, I would have shut up :D

Hey guys. How many time a minute. People ask u how to turn off the chk engine lite and tell u guys the car is running fine.--->> Cuckoo & gaga.

Heeee hawwwwwww!
Ps: 1 more. Christi just like the others. Always have 1 last symptoms forgot to tell us. The car stall every now & then ---> which I think she has some kinda pwr & grd issue to begin with. It probably had hidden codes from the factory side. That the ecm keep resetting and never realize. Cuz auto zone code reader only tell OBD2 not all factory code( misfire in OBD2 is a continous monitor but not necessary on other cpts & system on monitor & testing) which might related to problems. Thats why every1 and every shop should understand the sytem 1st by thinking and research which is cheap and free and understand their tools /equipments capability. Unless in this case a TECH2 gm scanner is available.

In case all of you forgot, ALL engines operate on the same principles of internal combustion OBDII is here to satisfy the Government! We had cars that were simpler to work on before the advent of computers.
I started working on cars at 12 Years old in the 60's
It would take all of 10 minutes to tell you what type of problem a car had and what to do to fix it! OBDII is to engines as ant-lock is to brakes. An add on!

Merlin,hmm....let me think ..in case u forgot ...the same technology of OBD2 bought us internet so we all can play long distant mechanic ...also we have cell phone...also cars that reduce emission to less than 1/1000 times comparing to 60's cars...as mmprince remind me ..point blank --> can't just take the good without the bad...i grew up in the 60's and 70's ..so i know about the 427 sideoiler,426 hemi and chevy mistry 406 small block..i nail an SU carbs 56' volvo lean problem with my 5 gas analyser combining with my latest snap on modis ignition scope too.... show me some1 who can turbo charge a gasoline engine with carburetor and run cleans with 500 hp?..overall think about this...a real mechanic gets pay a lot more than electrician and plumber comparing to the old days ...we are in a free market which service and products are supply and demand upon prices....agree?...as just my narrow single minded opinion..i believe if anyone is a real mechanic given enuff info about the system and equipments ..he/she should be able to fix anything that move with no if/and/or/but about it...sure OBD2 has its flaws and weakness..but look at todays late model 04' and up cars...running 22:1 Air fuel ratio . and OBDII codes are 80 % accurate to its enable criteria ...would it be more than add on or better improvement?..by the same token...we use the same technology to advance this country to be #1 super power in military ..the best technology in medicine ...still an add on???.....maybe most people here are not crossing both end of the spectrum .. i do...even hot rod..we build a stand alone sytem call mega squirt on a custom nissan 280Z here which i can change the injectors pulse,ignition dwell ,timing according to the manifold pressure with a stroke of the key
