po108 is map sensor manifold absolute pressure////0171 code means system to lean on bank 1 or2? 0174 code is bank 2 too lean ////0300 code is multiple cylinder misfire 0410 code is saj secondary air injection the other codes oxygen sensor. to me i would unhook battery for about 30 secs and the hook bc up to see how car runs if problem still persst i would say probbally compuer needs to be change.

In this case we go with what we know already from these codes you posted. You have a vacuum leak or a lean condition causing the P0171 and P0174. Those codes are like peanut butter and jelly, they almost always show up together. The P0300 is a misfire caused by the extreme lean condition.

1. Check for a vacuum leak at the boot between the throttle body and the upper intake manifold plenum. It's a stubby kind of boot, easily missed. This is a dealer only part.

2. Spray water on the upper intake manifold, check for RPM response.

The P1106 and the P0108 share causes. Replace the map sensor, not a sure thing but very high probability. If the cause is not a map sensor then the real cause is a clogged cat. Go with the map.

The P0410 and the P1415 share causes and is likely going to be a bad AIR (air injector reactor) also referred to simply as an 'air pump". These pumps had a problem because of the hose routing of injesting water and burning out the motor. Most often you will find the fuse for the air pump blown. that is basically confirmation that the pump is junk. If you confirm the bad pump, make sure you use part # 19515548 available at most GM dealers or a one day order or even internet now that I have given you the part #. the kit contains everything you will need to replace the air pump and hoses and the kit reflects all modifications made to prevent a repeat of the bad motor.



And lastly... the P0442............try replacing the gas cap.


Ok, thats all I got. I feel like I just worked a full day.

sounds like you fried the starter and solinoid.

How many miles are on it ? A few things . Are the fans coming on ? Turn the A/C on and see if fans come on . Maybe radiator plugged ? And last a blown head gasket will also do this .

1st try another batterry/ also let me knopw if u have security on this car

the sending unit and/or float assembly inside the fuel tank may be faulty. have a auto tech. test the wiring to the sending unit and the sending unit its self.

It would be just a bandaid and short term fix . Nothing better than just doing it right .

Somewhere on this engine's ignition system there is a ballast resistor. it's function is to allow full voltage during startup to allow easier starting and when the ignition key is released to the run position the voltage is reduced. if i remember correctly the old Chrysler white ballast resistors had two resistors in one. when you start the car the circuit currect flows through the 1/2 ohm side of the resistor and when the key was released the current flowed through the other side (5 ohms) so a hotter spark at the plugs during startup. Your mercury 1964 used I believe a piece of resistor wire rated at (?) but it is still referred to as a ballast resistor. I believe that your cause here is that this wire is open. Follow the circuit wires from the positive of the coil and you may find the cause. i do not have a 64 wiring diagram to refer to to get more specific.
