Question about 1994 Nissan Sentra 4-Door

2 Answers

Car idles rough, sometimes dies in reverse, it's worse in cold.

I've changed the spark plugs, wires, distributor cap and rotor and no change. When you pull the wires while the engine is running cylinders 1, 3, and 4 will make the car die. Pulling 2, though, there's no change. Does that mean that cell isn't getting fuel? Would this be a bad injector or another culprit?

There is two thinks either not getting fuel or not burning fuel properly, So as you say not getting fuel if its EFI Engine or if its not then we ll consider second one ..... Its mean your engine head valve are tight or missing, coz of not getting proper fire in piston cylinder & its leaked.
So steep #1 ,Take off tappet covet then one by one check tappets & check 2nd cylinder (or which is doing missing) tappet, Then adjust it & Make sure check all of them & adjust by manual book of engine, Then put it back cover & start your car engine & re check that plug wire which was not working......If its working then every thinks are okay, Or if not working & problem is same then open that plug & check it is it gap is okay & if every thinks seems okay then take compression test if its still leak then you have to take out engine head & replace the valves of engine head..... My advice at that time if you are not professional mechanic then concerned with it any professional mechanic.....
Best of luck

A cylinder that doesn't fire could be 1 of 3 things: no spark, no gas, or no compression.
Sure, it could be a bad injector, or clogged, but you should do some tests before buying an expensive new injector. You should first check the injector circuit on #2 cylinder. It's a pretty simple circuit, really. Each injector has 2 wires, a power wire and a ground wire. The power wire is one wire, which is spliced to each injector, and has battery voltage on it anytime the ignition switch is on or in "run". Each injector's ground wire is a separate wire going into the computer. When the computer internally grounds for a split second that injector's circuit, the injector sprays fuel out a tiny opening, a nozzle. You can check the circuit for #2, both the power wire and the ground side of the circuit with a test light. Post back and ask, if you want me to explain.
You also might want to check the compression in #2, just to assure you there is no mechanical problem causing a loss of compression in that cylinder.

Its just fouled some plugs again. Need an overhaul. If you just put a valve job on it it will just put more stress on the rings and will need it anyway. Not much you can do except change plugs all the time!

MAKE SURE WIRES ARE GOOD, to check injector Get a noid light and take that injector plug and plug into noid light it should light up everytime injector would pulse.(IT SHOULD BE A STEADY PULSE) contact if you need more help

SOURCE: 95 maxima rough idle

The injector could definitely trigger a misfire code, but you also mentioned that you had a mass airflow sensor code , that code code be responsible for te sluggish moment of the vehicle and rpm going up and down. However if you have a misfire onCyl#6 and the coil and the plug is good the ONLY other thing to cause a mis-fire would be the injector. To check the injector get a NOID light, you can get one at almost any auto-parts place. To use unplug injector plug from the bad injector and connect it to NOID light the light should have a steady PULSE/ligt flickering. If light flickers fine then injector is bad and will need to be replaced. If light doesn't flicker or flickers intermittently then you may have a bad wiring to that injector. Check if wiring is good, then you may have a bad cam sensor or sensor gear. Good Luck and contact if you need more help. Thanks for using FIX YA

97 chevy blazer rough idling problem? help?


It is hardly ever the spark plug or only the spark plug - generally for some reason there is a weak or lost spark and the reason must be found and rectified by carefully checking and then replacing any components found to be edfective - plug wires, coil, distributor cap, rotor (if fitted), wiring, connections and could conceivably even be the ECU. Perhaps the misfire is due to injector trouble...

Sometimes a fault with persist even after it has been "cured" until the fault code is erased with diagnostic equipment.

Tuned up car changed 02 sensor full tank of fuel still running rough


Oxygen sensor only report the condition of the engine the rough running condition can range from a worn sparkplug wires to worn sparkplugs to valve problems to injector problems. with the cadillac deville a tune up should be the first attempt to smooth the rough idle with the inspection of the cap and rotor cap and rotor do have a tendancy to arc internally and create misfire so does sparkplug wire that can leak spark voltage to ground and create misfire. the spark plug wire especially if they are brittle and hard can create issues

Wires and distributor cap too-they should be changed if you are going to rule out ignition problems. You can check the wires with a digital meter, but if you know they haven't been replaced in a while, do that-distributor caps are a little trickier in that they can hairline cracks or 'carbon' tracks that can disrupt the spark.

My 1994 Toyota Land Cruiser ALSO idles rough in cold damp weather.


If this only happens when it's damp out, chances are your spark plug wires are arcing. When was the last time they were replaced? If they're factory wires, they'll be marked with the year they were made on the wires. Usually these won't last more than 10 years or 100,000 miles.

If they're in question, change the plug wires, spark plugs, distributor cap and rotor.

Rough idle, dies when running slow


Not much info here, but I would do a tune-up. Change spark plugs, oil and filter, air filter. Disributor rotor and check distributor cap for cleanliness. Make sure spark plug wires are not arcing.
