On many nissan altimas I have found bad ignition coils. Usually one bad one will creat a problem. The slp gets gounded through the ignition coil. When the ignition coil is going bad it shorts out other systems. Go to autozone or use a method to retrieve check engine light. If i knew the code it would be helpful. When the car is running rough disconnect one ignition coil with car off. Restart car. If car runs worse that means that coil is good. repeat process. If you have one coil disconnected and the car runs the same that means that ignition coil is not sending spark to your spark plug therefore creating a misfire and making your car run rough. That check engine light is most like likely linked to your slp light. If you find a bad coil using this teqnique replace it, your car will run better. I would like to know your check engine codes and this will determine problem better. If you have a misfire code or a po1300 code that points towards a bad coil

Nissan Altima wont start


Check simplest things first. Make sure battery cables are tight and free of corrosion. You could be getting enough power to light up your dash but not enough to crank the engine.

2002 altima idling too high check engine light on


The first and easiest thing you should do or have someone do, is check under the hood for a vacuum leak, possibly coming from a cracked or broken hose. Check and inspect all rubber hoses, including the large ribbed hose running to the throttle body (Engine air intake from the air filter box). You can hear a leak if it is loud enough and will sound like a hiss. Your engine is idling high because of a vacuum leak.

U have an ignition related problem, have the system tested for the trouble code that is stored in memory any time the check engine light comes on to determine what is causing this issue. check engine lights have nothing to do with oil level or pressure, they indicate electronic control problems with the engine, trans or emission system.

2002 Mercury Sable-shakes with acceleration


You describe this as an acceleration problem however, if the car does throw a check engine light it should be recorded in system memory so it can be pulled by scanning with and OBDII scanner. It sounds as if the car is being starved for fuel on acceleration. Check the fuel lines for kinks as well as check the fuel pressure. The problem could be a faulty fuel pump that has yet to completely die.

Altima


My both low beams headlight does not come on (2004 Altima). I replaced the bulb, checked the fuses. They all seem okay. I'm wondering if there are any other relays that I need to check. If it's in the harness then, I guess I'll have to bring it to the dealer. Hope not. Any suggestions?
