I have a 2002 Nissan Maxima with 120,000 miles. The engine hesitates from a stand still but drives ok when on the highway. It also feels like its surging slightly. There are no codes and the tranny shifts fine. What would cause this? Plugs were replaced but not the wires. Idles normally.

wheel bearing or axle shaft

they are correct change the fuel filters

with a hand held diagnostic computer it can be done in about an hour. Drive the car as an owner it could take up to a month. It is the driving condition , not mileage that resets the ECM. You have to drive on the highway at certain speeds for a certain amount of time, then in city driving, stop and go and at certain speeds for so long. The computer guides you threw it. If you only drive city or highway you may never get it to reset.

hello, also check plug wires,distributator, cap and rotor button, you can check plug wires,at knight time, crank engine, with hood up, walk around car, look at plug wires while motor is running, see if any sparks are coming from plug wires, also if it clunks, like you said, you may have broke motor mount, transmission mount, check for air lines leaking also

You have years to change the belt. It's a good idea to change the belt at about 100,000 - 120,000 miles, whichever comes first. Hope it helps!

Your ac pulley may be worn so the engine needs extra boost and power to run it thats why when it is in optimal power (highway-- high engine power)as opposed to idle(low engine speed) it runs. You might need it replaced.

Replace your valve covers do to clogged pcv piping

no it is not it could be the trans a vavle or a cracked head

You can wait its just fine, However if you ever start to notice oil leaking from front cover, then you will need to change. If there is no loss in power feel sluggish especially on take off, Its almost impossible for these type of chains to break. So enjoy until the wheel fall off..lol. good luck

i have a 1998 nissan maxima when the engine is cold the engine will cut off when you first crank it. It will cut off but i can usually get it going the second time. After engine warms up car runs great. Why does this occur
