my 92 maxima misfires in the top left I changed sparkplugs rearranged the coils and it still misfires in the same one... imma bout to spend a grip on injectors hoping that's whats wrong. it holds back power and sometimes it wont even jump over 3500 rpm just cuts out. any other ideas???????

 

Sound like a injector. Did you check to see if you have spark thur the wire?

 

Check the power transistor too. Will give the same symptoms - misfire that does not move cylinder despite swapping plug and coil.

 

Throwing parts at her will only thin out your wallet...you need to run some diagnostics on her. Is the cylinder getting good fuel/spark? Does it have good compression? Swapping the coil packs out was good but you need to go further. You don't want to buy an injector if you don't need one. You could have a bad lifter/valve/cam... Did you atleast ohm out the injectors?
Start doing your research...there's plenty of info right here on Maxima.org.

 

Ya I did a Lil playing around even bought Whole coil setup when I changed spark plugs

 

Can I check the maf by disconnecting the harness? If not does anyone know where to snag a cheap one? So that I can test it or atleast have an extra.

 

And what's ohm?

 

Ohms is Resistance...voltage cause current to flow in a closed circuit, the components of that closed circuit are the load/resistance. Voltage equals current(amperage) x resistance(ohms). E(voltage)=IR(current x resistance) or 12v=.5amps x 24ohms
