20 Most Recent 2003 Nissan Maxima Questions & Answers

The first thing I would check is the spark plugs for condition and gap. That could be the misfire. Shutting off is a whole new mystery. Misfires would normally trip a P0300 code, whereas cutting off wouldn't necessarily do so. I would check for codes and historical data anyway.

Modern car engine control systems rely on input from several sensors to regulate the engine's performance as well as its emissions and other vital functions. When these sensors fail to provide accurate information, the driver may experience increased fuel consumption, driveability problems, emission failures, and other problems. One of the most important sensors in modern cars is the oxygen sensor. Also known as the O2 sensor because O2 is the chemical formula for oxygen, the oxygen sensor monitors how much-unburned oxygen is present in the exhaust as the exhaust exits the engine. By monitoring oxygen levels, the sensor provides a means of measuring fuel mixture. https://mailordertuner.com/blogs/news/02-sensors-and-why-they-are-important

thermostat in a 99 maxima is right above the alternator. just look down and you will see a hose clamp and a hose. that's the thermostat housing. you will remove the whole housing (3 bolts),because that's the whole thermostat.

check the fuses- some car makes uses individual fuses per side. Just saw that in a mitsubishi- I believe Nissan does that too. Those fuses are probably under your hood.

Unlikely a leaky oil seal would trigger a fault code although the oil might contaminate electronics and do so though I think it is unlikely. I think you should look elsewhere for the performance problem.

Did you ask auto zone they usually tell you what's wrong otherwise go to the dealer. As far as your fuel gage it may be the cause of all your problems as they are part of your fuel pump that's in your gas tank it should be able to be reaches either under your back seat or in your trunk.

Keep shopping! Off set is basically how far the wheel sticks out of the wheel arch. It is measured in millimetres. + or positive offsetting means the wheels stick further out, wheels are wider apart. You are safer looking for another set of rims at +40. The wheels stick out too far you can damage axles, wheel bearings and wheel nuts. (£££ $$$ OUCH!!).

sounds like exhaust manfold to cylinder head gasket is blown, make sure you have got the tire pressures correct, get your shock absorbers checked one may be partially siezed

when was the last time you had your spark plugs changed

IF IT MAKES NOISE IN NEUTRAL WITH CLUTCH OUT AND GOES AWAY WHEN CLUTCH IS DEPRESSED THAT MEANS INTERNAL GEAR OR BEARING IS MAKING NOISE.

code p 0432 is main cat converter bank 2 --efficiency below threshold ===causes -- cat converter---wiring heated oxygen sensor (HO2S ) in the bank 2 manifold before the cat converter ave a compression test done to determine inlet valve seat insert loose if you have a problem with it there should be a bit of a miss, or it should change with rpm could be a cam lobe failing and the noise should change with rpm

Rich fuel=black smoke. Oil burning=blue smoke Coolant burning=white smoke

When is the last time the engine had a tune up with new spark plugs and an inspection of the ignition coils? Ignition coils were a pretty common issue with the V6 engine around that model year.

Broken/damaged wiring,most likely at one of the front wheels. 90% chance broken wire. 5% chance ABS unit. 5% chance pickup sensor at one of the wheels. Plug it into a scanner and check feed at every wheel while flexing and pulling on the ABS wiring at each wheel.

get a new mechanic who knows what he is doing plugs for ECM controlled engines very seldom need changing ( most will last for 5 years or platinum plugs will last a life time ) --- nissan , toyota , mitsubishi and other cars with v 6 engines where it is almost impossible to replace the rear plugs all use platinum plugs for those plugs as they are never replaced -- if you need 6 coil packs then the engine would not be running best find an accredited service shop with experience on your vehicle , have the codes read and have the problem fixed properly with fault code storage in the ECM, repair by replacement is not an option but a total waste of money
