Hi!!
What all this codes have in common is that every single one of them can be caused by a vacuum leak, so carefully check for cracked, loose or disconnected vacuum hoses, wiring to the coils, fuel pressure regulator, fuel injectors, specially on cylinder 2.

  • PO100 - Possible causes are wiring harness failure, air leak or defective hot film MAF sensor
  • PO130 - Vacuum leak
  • PO170 - PO173 - Possible causes are air ingress (leak), fuel injector failure, pressure regulator failure or mechanical wear of engine. Inspect and repair as necessary.
  • PO300 - possible causes are vacuum leak, wiring harness failure or ignition coil defective.
  • PO302 - If limit value for misfire "harmful to TWC" is exceeded, the MIL flashes immediately. If too many combustion misfires occur in one cylinder, the cylinder is switched off (cylinder selective fuel shut off). After the affected cylinders are shut off, the MIL changes from flashing to continuously lit until next time the engine is started. If combustion misfires are recognized, the fault code P0460 or P0462 is set if fuel tank level is too low (fuel reserve indicator light is on). Combustion misfires due to a shortage of fuel are recognized by means of this additional information.

NOTE:After cylinder cut-out system is turned off, the system monitors (through misfire detection) if all intake and exhaust valves are open again.
NOTE:Misfiring may be caused by many faults in the fuel injection system. Usually a misfiring fault is stored with faults pertaining to other components. An engine mechanical fault could also cause a misfire condition.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

SOURCE: 95 legacy l codes p0100 and p0170

P0100 is a MAF circuit problem, check the connector to the MAF sensor, look for water or signs of corrosion on the connector pins, if no problem is found you may need a new MAF sensor. The P0170 is lean fuel control condition and is related to the MAF problem.

What you have is a real mess

You have so many different codes that aren't
even related, that I 'am not going to list them

You need a repair shop or dealer

You have air flow,couple oxygen sensor,cam sensor
speed sensor,real nightmere

I would look for something simple or some common
denominator.

I have no idea where I would start on that

Obviously, I would have to road test & use the scan tool
to check data, but I think all those codes are squed somehow
eg: not doing you any good

Are you sure it is a trans code. Everything that I have found states that P0170 is a fuel trim problem?P0170 Fuel Trim Malfunction (Bank 1)

The code P0170 means that the air-fuel mixture coming in to the engine is too lean, or too rich. Usually it's the lean condition that causes this code. The code P0173 means the same, only for the Bank 2. Some car manufacturers list the description for the code P0170 as self adaptation out of limits.
The code P0170 could be caused by a number of reasons, such as vacuum leaks, bad PCV valve, or other parts of crankcase ventilation system, low fuel pressure, bad oxygen sensor, bad MAF sensor or even a bad EGR vlave.

Trouble Code: P0170 (3.4L V6 VIN V Auto)
Fuel System Too Rich or Too Lean (Bank 1) Print this code dataprint_icon_codes.gif Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details

  • Air being drawn in from leaks in engine gaskets or other seals
  • Base engine "mechanical" fault affecting one or more cylinders
  • Fuel control sensor is out of calibration (i.e., ECT, IAT or MAF)
  • Fuel delivery system supplying too much or too little fuel at idle or cruise (e.g., faulty fuel pump or dirty, restricted fuel filter)
  • One or more fuel injectors is dirty, leaking or stuck open/closed
  • HO2S element is contaminated, damaged or it has failed
