Lights came on and engine running slower - 350Z Nissan Cars & Trucks

That sounds like a mechanical engine failure not an electronic control issue.

There are separate flashers for directional and emergency lights so they might not flash at the same rate.

lights are pulsing because the engine is so the alternator brights the light s as the engine runs faster and dims when it runs slower. the lights are not part of the problem. there are many things that will make an engine do this, probably a sensor like oxygen sensor or some other. is the check engine light on? either way it needs to go to a garage

IT's those short drives that burn down a battery! The starting of an engine requires mucho electric to get it running. The alternator then charges the battery, but slowly! If you also have the lights and stereo on it is even slower. Get the battery FULLY charged with a commercial battery charger. Then check to see if the alternator is charging up the battery after you start it. If not, replace the alternator. If the battery dies overnight or in a few days...replace the battery.

First check your relay, under hood . But you also have another filter in your tank. You can still build up pressure on eather . Good luck to you.

alternator problem or voltage reg. prob...

Replace the alternator,it is not charging like it is supposed to.It should read at the battery with the engine running ,and head lights on,and ac on high blower motor setting,13.65 volts,to 14.25 volts,no less.also slow charge the battery to get a deep full charge,cause it will be low .

Bracket racing is trying to run the same time, time after time. Running agaist some one faster or slower. So say you run 10.90 they run 9.90 you need to start 1 full second ahead of him and not try to hurry when you see him catching up. You need to dial in your start time when he stages. which in a case like this you just punch and go on the .4 or .5 sec. if you running against some one slower than you you dial in then difference in time if your running 9.90's they running 11.90's you dial in 2 second of delay on his stage or who ever hits the lights last. Keep the same delay or jump the light. Always dial in a bit less than your fastest time, that way you never break out.

sounds like a thermostat,take to auto zone they will run a free test...but it's more likely yout thremostat

Running slower, meaning drivability issues? Push the gas pedal and response is slow? Idle is lower than normal or engine is 'coughing'?
Might be an oxygen sensor, usually an easy fix, but parts are expensive.
