SOURCE: COLD START ROUGH IDLE

I hate to be the barer of bad news, but may be the head gasket.

My car started with rough idle. Then very hard to start in cold weather. Next started overheating, but no output from heater. Trickling sound from behind dash board. Overflow bottle overflowing.......

I replaced the water pump, radiator cap, thermostat, coolant, fan belts, power flushed the system. Nothing worked. Some research gave me the answer.

The head gasket leak was allowing exhaust gases to enter the cooling system, displacing the coolant. After use, as engine cools, coolant is sucked back into the system and coolant seeps into the cylinder. This gets worse over time.

First thing you'll notice is the rough idle as the spark plug burns off the coolant in the cylinder. (This is especially true at low temperatures.) If it is the head gasket, the other symptoms will follow as time goes by.

Make sure you have the plug wires on the correct plug. Check the ignition timming to make sure it is correct. After running for a few minutes pull the pluggs to see whitch cylinders are running rich. The fuel pressure and volume need to be tested.

Additionally, try checking the power transistor. I will send the test. Also make sure the coil has a good ground...

SOURCE: my 2002 nissan sentra xe can't start. it wants to but it just won't turn over. it sounds like the car is out of gas but we just put gas

H Mkawaauhau, If the engine is turning on the starter but refusing to start, you may have one or more of several problems. I believe you should have a diagnostic scan carried out on the vehicle. the problem would seem to be the crankshaft or camshaft pick up sensor, a fuel delivery problem or the on board alarm anti theft unit. Regards John

2001 Nissan sentra gxe starts when engine is cold, rough start when engine is warm. What do I have to fix?


When a hot engine is hard to start, most of the causes are fuel related problems. Fuel cannot circulate well due to the way in which vapor blocks it.

My 1993 nissan sentra 1.6 wont run and check engine light wont turn on,bulb is ok


Could be any of several things. If the crank sensor is marginal and not sending pulses, the fuel pump is shut off. This is for safety. The pump is energized for a few seconds as key is turned in preparation for starting then engine must rotate normally to keep the pump on. If it stops, in a few seconds the fuel is cut off.

What causes the 2002 nissan se r to backfire


Sounds like an ignition or timing problem.
Is the check engine light on ?
This engine uses a direct ignition system which means each cylinder has a coil on top of the spark plug. It could be as simple as worn out spark plugs.
If you had said the engine backfired and was hard to start, but no flooding, I would also look at low fuel pressure. But too much fuel causes flooding.
A faulty throttle position sensor could cause all of your symptoms, but it should set a trouble code and turn on the check engine light.

I had my 2000 Concorde act up after washing the engine.
Water at the spark plugs would let it start, but when the engine got warm the water vaporized and caused the miss. Check around the plugs, wires, and coil/s for moisture.

Nissan Installed throttle reprogram


Here is the way to do it without the nissan scan tool. Make sure to follow all steps and it it best if you use a watch with a second hand.
1. Perform "Accelerator Pedal Released Position Learning".
a. Make sure that accelerator pedal is fully released.
b. Turn ignition switch 'ON' and wait at least 2 seconds.
c. Turn ignition switch 'OFF' wait at least 10 seconds.
d. Turn ignition switch 'ON' and wait at least 2 seconds.
e. Turn ignition switch 'OFF' wait at least 10 seconds.
2. Perform "Throttle Valve Closed Position Learning" .
a. Make sure that accelerator pedal is fully released.
b. Turn ignition switch 'ON'.
c. Turn ignition switch 'OFF' wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound. 3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic 'PREPARATION' (previously mentioned) are in good order.
5. Turn ignition switch 'OFF' and wait at least 10 seconds.
6. Confirm that accelerator pedal is fully released, turn ignition switch 'ON' and wait 3 seconds.
7. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal. 8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the MIL goes off.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
13. If idle speed and ignition timing are not within the specification, the result will be incomplete. In this case, more test needs to be done.
