hi guys'

i am new to this site .
i have a 93 maxima that has developed a miss.
i traced it down to the number 3 cylinder by pulling the spark plug wire while the enguine was at idle.

so i am going to check compression for that cylinder and also test injector.

is there any thing else to check?
and where is the ecu mounted ??

great site and thanks in advance..

 

Have you tried a tune up??

Check your original post about the location of the ecu..

 

don't forget to pull the plugs and check their condition

 

pull the injector harness and c if has developed the green corrosion. if it did get an old tooth brush a car battery thats layin' around and dump the brush head into the battery acid and brush it onto the injectors and injector harness. let it dry up completely and reconnect the harness and start the car and c what happens. do the same procedure to the coolant temp. sensor and also crimp the female connectors a bit so that when u plug everything right back up it should be a tighter fit vs a loose fit.

 

i have done a complete tune up.

that is plugs, wires, cap and button,pcv air and oil filter..
thanks.

also there is no corrosion in the wires or injector plugs..

i will check the temperture sending sensor

thanks
