Here is an ALLTEST BrainMaster Scanner Model 3226 that I have used to analyze problems on all the Fieros that I have worked on. It is a Vintage unit but it works perfectly. It will provide all fault codes plus give you live data on all sensors and any info coming from the ECM. With it you can do an analysis of timing fueling and general operation,
There are some of the parameters that it shows:
Block Learn/Integrator
Coolant Temp
Battery Voltage
RPM
Loop Status (closed or open loop)
MAP Voltage
TPS voltage
O2 sensor Voltage
IAT voltage
EGR solenoid status
Troble Codes
Spark Counts
Comes with a carry case and ALDL conntector, and two others for Ford and Chrysler cars
With this tool anyone can pinpoint engine/sensor problems on all 84-88 Fiero's V6 or 4. Its easy to use and I'm selling only because I have an extra.
Price is $35 + $12.00 shipping (lower 48)
