I'm not as smart as you guys. I start with what's simple and easy first and work my way to the hard things. So to start I tighten the battery connections, check and clean the grounds, remove the Delco coil pack and ignition module and clean the grounding plate and idle air control and chamber. If that doesn't do it then I start with swapping the MAF Sensor, then drive the car a bit. If that's not it then I swap out the coil pack and ignition module then drive it a bit. Then I swap out the O2 sensor and drive it some more. Last is plugs and wires because I keep a log in each Reattas owners manual on service interval. But the big difference is that all the parts that are swapped in are previously tested by me before I have a problem. I go to a salvage yard get the part install it and take the working part and put it in storage. Exception is the O2 sensor, those I buy new.

Interesting information, thanks. I just replace the sensor as a matter of maintenance. All the work is in the removing and replacing it and I do not have the test gear as described above. I guess I do have a handheld o'scope that would generate a similar wave form but not the hookup that the technicians would use. For a sensor that is less than $20, testing would make sense if it fails to do better, but from the limited information so far, the original is working.

Just now leaving Saigon for a 3 day stay in Bangkok, then home. Saw a lot in Vietnam. Saw Hanoi Hilton but all the American cells were tore down. They talked mostly about the French occupation and little about our soldiers incarceration There were propaganda pictures of happy soldiers getting physicals, playing volleyball and basketball. Saigon we saw the tunnels the North Vietnam soldiers used and the various traps they used to injure US soldiers. Was very interesting, and gave me a new appreciation for those that came and served. Also saw the killing fields of Penhm Pehm. Walked away thinking how can people be so cruel to each other..
