When you remove the upper engine cover,(the one with the big NISSAN logo) you will see the coils in BANK2, right at the radiator. BANK1 coils are under the upper plenum assembly. (top of the engine) You need to remove the upper plenum to access the coils in the back. You will also most likely need the rear BANK 1 rocker cover assembly, because oil leaks into the plug holes.Not really a job for someone who doesn't work on cars much.

Why does my motor have a pinging sound


You did not mention when this pinging occurs (all the time? idle? lugging under load?). If it is in fact in the engine, it is most likely a timing issue which can get complicated because it could be caused by a problem with the distributor, timing chain or chain tensioner, one or more faulty engine sensors, etc.

However, there are other causes of this noise. Most pinging noises at idle or low RPMs are not usually in the motor itself but rather from rotating parts that periodically touch something, and often happen when something comes loose or is bent, bearings get worn, or something made it into the engine compartment that shouldn't be there (a tool, a rock, etc.). Typical examples are worn out HVAC fan, cooling fan or AC compressor clutch bearings; a cooling fan blade touching metal or a loose shield; and so on. If this is the case, you should try to locate exactly where this noise is coming from - a stethoscope from an auto parts store may help.

Check your oil. Might be low, which can cause lifters in engine to make that pinging noise.

I have a lincoln mk lll won't start when key is on


That should be easy for you. Ign sw,safety sw,ballast resistor if you have one,bad ground at coil. How about starter solenoid wires on wrong terminals. Did the old starter work as wired now!! How about a schematic to make this go away quicker. Iam a 60's guy also like the mk111 . Wife has a 2004 LS

ROUGH ACCERATION


I had the same problem! check your spark plugs and if you have a scan tool check your firing order. You may have a misfire. I ultimately changed out the coil pack on cylinder 6 and its running sweet now. You also may want to clean down the intake mainfold and that sensor. I've got 133K on my expy and she's still running!
