2000 maxima-codes 0305 and 1320

[cocotazo]

Anymore ever had their service engine soon light flash maybe 5 times while driving and then have these two codes appear in OBD. The car idles rough for about 30mins and another 20-30 min after resetting the codes. Then all is fine. MAF and O2 sensors have been replaced recently.

305 should be a cylinder 5 misfire or multiple cylinder misfire. 1320 is ignition signal. Could be the crank sensor or coil harness connectors. You might look to find a mechanic somewhere near you that has a Consult.

remove the ignition coil no. 5 & inspect it, if there's no oil,replace the coil. replace it asap or else bank 1 cat will fail.

the 305 code is for a missfire on cylinder 5, the other code is for a cat code. Nissan has an updated coil pack, the only problem is that they should be replaced as a set and that gets expensive quick. If the cat code does not reset after the coil pack is replaced you have to replace the cat and that is stupid money because they come in an assembly with the y pipe.

code 1320 is ignition primary signal malfunction, no cat. converter code yet.Dealer always recommend all six coils, u have option to replace only one w/c is no. 5 only.
