my 89 camero rs is flaching a 34 code , i was told it was the
maps or maf but none of the parts stores have the maps that
i have any suggestions please

 

According to my manuel if your V6 is fuel injected it is either the MAP or MAF sensor. I checked www.partsamerica.com and found only MAF's available for your car ranging from $50.00-$220.00. If you V6 is carbureted then its the DPS or Differential Pressure Sensor. Partsamerica doesn't even list a DPS. If your car is equipped with a MAP then its either a trip to the bone yard or dealer for that item. I would check the MAF if so equipped and see if the wire inside is still in one piece.

Good luck.

 

An 89 2.8 does not come with a carb in any version, FWD or RWD. Most likely your car has either a defunct MAF sensor or relay (the relay is cheaper to replace and is the same as the fuel pump relay), or the fuse mounted on the frame rail (with black and red wires, not orange and red, that one resets the ECM if removed). The relay is mounted on the radiator mount to the passenger's side of the engine compartment, or near the charcoal can, still mounted to the radiator mount, tucked in the upper corner.

There is a simple test for the MAF. Start the engine and let it warm up. Using a screwdriver handle, tap on the MAF. If the engine does anything other than what is was already doing (running correctly, I hope), such as hesitates or stumbles, then the MAF is bad.

Remove the sensor (should be a black cylinder mounted in the air duct at the front of the engine on a Camaro) and look inside the engine end, with the other end pointed at a light source. Looking at the orange sqaure inside, note whether this square is wavy looking or flat. If it's not flat, then the sensor is bad.

If you have an Advance Auto nearby, then you can snag a NEW MAF for $80.
