SOURCE: rough

if it seems like it's misfiring... it seems to be the time of year you need to put a bottle or two of gas line antifreeze in our tank.

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: nissan truck idles fine, does not acelerate well, and misses

Try to disconnect MAF sensor(mass air flow sensor) or MAP sensor (manifold absolute pressure) , I don't know which one you have , (suppose to have either one) , when engine running and see if it becomes any better , if it did , then it's your problem.
Just remember one thing , if your check engine light is off now , it will be on after you disconnect any above mentioned components.
Easy to reset , disconnect battery for 30 sec.

SOURCE: we changed spark plugs &

Here is the firing order diagram for the 5.0 liter (305), 5.7 liter (350) and the 7.4 liter (454) V-8 engines (note position of locking latches/screws between the 3 and 6 and the 1 and 2 terminals on the distributor cap). Let me know if you need the 4.3 liter V-6 engine diagram (hopefully not in a 2500 series truck) or if you require any further assistance.

Runs rough after tune up


You did by yourself or a mechanic did for you...?
Q: What parts did you changed?
- Spark plug wire and rotor and plugs?
If so you might connect the plug wire to the wrong spark plug. or either way
Or if it has a distributor cap and it has been removed. The new one
is not line up EXACT location as the old one.
Solution:
-Check timing and set to correct degree that it suppose to.

1989 nissan maxima, rough idel. alredy replace spark plugs and air filter. any other suggestions ..i.e. ignition, distribtor, fule pump, injectors? thanx for your time.


Distributor cap. Take off and see if the metal leads have corrosion. It is what connects your spark plug wires. Usually have to replace this a couple times a year!

How to change te spark plugs


Hi: If this is your 1st time to Change your Spark Plugs, I recommend that you First of All Get the Correct Spark Plugs from your Auto Parts Store, Then Locate your Spark Plug Wires which run from your Distributor Cap to your Spark Plugs.If you have a V-8 There will be 8 if you Have a V-6 Then You'll have six Spark Plug Wires and 1- COIL Wire which is located in the Center of your Distributor Cap to your Coil. It is the Shortes Wire.I Recommend you ONLY do 1-Spark Plug at a Time, This will Prevent you from getting any of your wires Crossed which will Cause your Engine to Run Rough ,Back Fire or Not even Start,So just Pull off 1-Wire From Spark Plug and one Wire From Your Distributor Cap, You'll Need a Spark Plug Socket Probally 5/8th in. And a Ratchet and 2- Different Size Extensions to beable to reackh all your Spark PlugsNOTE!! Buy you a Spark Plug Wire Tool there not very Expensive but well worth it,This was you Can Pull the Wires with out Damaging Your Wires.And you Might Want to Put NEW Spark Plug Wires On as well, If So and I do Recommend This. And Again Just do 1- Wire and Plug At a Time So you'll know you Have Not Crossed any Wires. Hope This Helps You ,Please Respond by Voting on This Problem And How it Helped You. Thanks From WYOCWBOY

Hello, I have a 1999.5 pathfinder and we had the timing belt and head gasket changed last year. Ever since we have had problems with it being sluggish to start and idling rough sometimes. In the morning...


Try measuring fuel pressure, if out of specs it could be the problem. should be 34 psi with the vacuum line at the fuel pressure regulator plugged in and 43psi with it unplugged. If out of specs. you'll need a pump.

1991 sentra 2dr 1.6 L rough idle in park and in drive at stop


Sounds like misfire. Change spark plugs, wires, cap, rotor , fuel and air filters. Check for oil in spark plug holes. if oil found change valve cover gasket spark plug orings. they can leak oil into spark plug holes and cause misfire.

1995 Alitma ran rough and stalled


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!
