Mile. I inherited someone's leftovers, a 99 Infiniti QX4.

Customer Question

Hi Mile. My name is***** inherited someone's leftovers, a 99 Infiniti QX4. Codes p0325 and P1336. Previously got new ignition parts, and an air flow sensor, but did not solve the rough running hesitation problem. I threw in a crank sensor, but to no avail. Fuel pressure test was good, has spark, and injection pulse, although the noid light was weak at times. Any input would be appreciated. Thank you.

good afternoon my name is ***** ***** I will assist

first, check the connector for the crank sensor for any damaged pins. make sure they are good and tight.

check the flywheel as well to be sure the reluctor is not damaged. that is a real possibility.

ignore the 325 code. it is a ghost code. nissan had issues with 325 coming up on any code.

Not gonna help with the hesitation problem since the crank sensor doesn't control the engine, it's only used to DIANOSE misfires.
