SOURCE: 1999 nissan frontier is idling rough the truck

This can be your Idle control valve, when you turn the air on it puts the engine under load and your computer will increase the idle automatically to prevent the engine from cutting out.
When you are standing still and the car is shaking, by touching the accelerator very softly does the shaking stop? If so check the idle control valve.
I hope this will help.
Regards
Sam

SOURCE: 1999 chevy suburban 5.7 L. vortec. Can a bad

i do believe it will not start with out it if you can hook up a scan tool to it crank the engine and look at rpms while cranking should read about two hundred forty rpms thats what fires the injectors the cam sensor tells the computer what cylinder is ready to fire next also scanner will set the cam timming.

SOURCE: My 2000 Nissan Frontier has sputtering problems

your tach is run by the engine computer, possible cause. also by the crankshaft position sensor, most likely cause, I would start there. some sensors will run within perimeters and be bad enough to cause a lot of problems

2005 Nissan Path:replaced batt, alt, plugs, coils due to rough run & smoke. 1st smoke was blue after new parts it's more gray or white. New plugs smell like fuel. Exhaust is rich in fuel smell. Ideas?


Blue/grey smoke is typically engine oil burning.

Grey/black smoke is typically excess fuel (or insufficient air).

White smoke is invariably water that has turned to steam. (water is a natural product of combustion as well as the stuff the head gasket keeps out of the cylinder).
Sometimes an engine can emit a fine mist of unburned fuel that seems like white smoke.

Clearly your engine is burning some engine oil. Perhaps the valve stem oil seals are failing. When an engine noticably burns oil it must be realised this isn't good for the oxygen sensor and catalytic converter and it is inevitable the life of these things will be shortened.

It is doubtful the replacements you have so far carried out will have changed anything and it is likely to be coincidence the colour of the smoke has changed.

What is needed is a diagnostic check to inspect the live data from the sensors when it will probably be found one or both oxygen sensors will need replacing and perhaps other things have grown tired too - at an extended mileage an injector could start dribbling or the spray patterns be so poor the engine won't be able to burn it all and then it will be expelled into the exhaust.

Why my 2002 Nissan Frontier is missing and smoking a lot ? Smok smell like gasoline...


Hi,if its not the spark failing on one of the cylinders then you will need to do a compression test to see if the inside of the engine is ok.all the best.

Reasons for cylinder misfires


Ford coil on plug systems are multi strike ignition (spark) under 1300 rpm then go to single strike a single cylinder misfire can be created by several things . #1 Test engine compression on a cranking engine compression it should be around 150 lbs but if gauge reads different COMPARE to other cylinders that work fine #2 check engine running compression this will be around 120 lbs then rev over 2000 rpm and check pressure drop again COMPARE to other cylinders that work fine. any drop would indicate valve train problems. #3 All internal engine is fine then external problems are present vacuum leaks and or fuel injection volume is low.

#1 CYLINDER WONT FIRE


no year, ?

try a new spark plug e and then if wires to spark plug , replace that too. and cap and rotor if it has that....?????



then when spark is good, check compression with any $20 gauge.

no year, i give up.

1976 accord? surely ive no clue.



smoke has 3 colors, (my rules not ASE)

1 black fuel (flooding etc) can seem gray but is black .

2: white and lingers., oil burning , bad. news.

3: white and fades fast, is STEAM, like moms tea pot, look next time..

smell white smoke, smells sweet, its toxic antifreeze.

smells like oil dripped on an hot exhaust? that is the smell of oil burning



smoke where, under front of car, or at the end of the tail pipe. ?????????????



how you like my smoke rules, even mom can figure it out.

check the compression in all cellenders you might have a blown head gasket, burning smell might be the gas in blown cillender not igniting

Why is 2003 Nisan Frontier Super Charged truck smoking and 4th, 5th, and 6th cylinders not firing after spark plug change? Put old spark plugs back in no change


If the engine is smoking and you have misfires on three cylinders, this is not a good thing. The best course of action at this point would be to pull all the spark plugs out and perform a compression test to help evaluate the extent of the damage.

Rough idling,seems to have power loss,and takes more oil than usual


is there smoke coming out of the exhaust? if so what color? if it has white smoke is usually a blown head gasket. if it is a bluish gray it is oil. check your radiator when it is cool. if it appears to have oil in it it could be a blown head gasket. if you leave the radiator cap off start the motor, if you rev the engine and coolant shoots out of the radiator (compression from the cylinder forcing water out) it is a blown head gasket. this can cause the motor to run weak and idle rough and oil to disappear.
if you happen to have a compression gauge take out all of the spark plugs look at the spark plugs if they all look the same or is there ones that look black and sooty(running rich) or looks green(burning antifreeze/water) white Burning hot) http://www.dansmc.com/spark_plugs/spark_plugs_catalog.html
check the compression of each cylinder it is easier if you have an assistant for this. place the gauge over the spark plug hole crank the motor once or twice. the gauge should be around 120 psi (pounds per square inch). if all of the cylinders are under 120 psi more than likely you have worn or broken rings which will cause low compression causing it to run weak and consume oil.

2005 nissan frontier wont start i have fuel and spark. engine cranks over but no start


Take one of the spark plugs out and let us know what it looks like. Dry and light grayish tan means you have spark but fuel supply problems. Wet spark plug that smells like gas means it is more of a spark issue.

Good Luck

Electrical problem


If the spark plugs are burning all the time it means youe getting too much fuel to the engine, check your fuel filter and replace if needed.
