For example..if you have a current insp sticker oh you cant drive it..have it towed, insurance typically covers the cost, tow her to a modern shop that will do a diagnostic and pay the $150 beans and go with what codes they tell you per the CONSULT print out..I did that 2x..codes all over the place..cause of the juust starting failure of the head gaskets..I could "see" something funny going on as I'd have noticeable high gas milage and using a $15 thermo infared temp gun, that one side of engine was way hotter than the other side, yet still not overheating etc..yes the consumer available code readers only show you a wee window of codes and what they mean. I worked a 2 yr stint at a modern collision auto body shop..with out those uber expensive snap on portable reader and diagnostics AND TRAINED TO USE THEM, a shout out to the auto technicians! we're clueless etc ,..its jusst the way the business is man and with an older car..gotta go old school streetwise and roll up the sleeves and figure her out..watch youtube, there's freelance auto-techs that use those snap on diag. equipment for troubleshooting things..ie a maxima electronic engine mount shorting out the ECM while driving etc..the disg. shows the voltage jumping depending on the rpm etc..id BE VERY CAREFUL NOT TO BLOW YOUR ECM AGAIN..the IACV sends a bad signal, to high a voltage, to the ECM as it normally does and .."puff"..i've read that scenario numerous times with after market IACV's.."..." i bought two IACV's then finally went with an OEM then it fixed it, or same scenario and the aftermarket IACV would work for say 3 months or 6 months and delaer or shop quoted $$$$ repairs..guy gets an OEM IACV..fixed and never failed since..on the Pathfinders R50 3.5 etc..and consider it this way..its a process of elimination too..worth gold when trouble shooting..its the only way...
