SOURCE: 1987 nissan pickup (z24) acts like there is a govner.

It is your coil. One coil cuts out under load and the other one runs full time. It'll run on either coil alone just fine. Your problem is that the one that is supposed to run full time has gone bad, the other coil which is supposed to cut out under heavy load is the only coil running your car. When it cuts out, the truck wants to quit until you let off and the computer (ECU) allows it to come back on. Should be able to find a new coil for $40 bucks. Good luck.

SOURCE: I have a 1986 Nissan Pickup D21 that bogs down

your carberator is gummed up. Go to the auto parts store and get a can of seafoam fuel additive. Read the label so you get enough but as I recall you put in one ounce per gallon of gas. Run that through your pickup for a few miles and it will purr again.

1994 nissan pickup, runs rough. wont hardly run. cant find the problem.

It could be many different things. Check the vacuum lines. Check spark plugs. Check compression in engine, check fuel lines filter and injectors or carb. It's sounds like a misfire which can be caused by incorrect fuel, spark, or compression. And sometimes they run rough because vacuum pressure is incorrect or line is leaking. Start with the basics and go from there

I bought a second car for utility use; B6000, 1994, p/u, standard trans. Only when starting and running when the engine is cold, it runs very rough and difficult to idle. At normal operating temperatures...

a coolant tempurature sensor will make it run to rich if it is bad. run rough at idle, and produce black smoke, engine may stall out. it also causes retarded timing, slow idle speed, cold hesitation or stumble, poor fuel milage. good-luck!! if light is on check for problem code. this will guide you in the right direction. if no scanner, any auto parts store will scan for free. repost if need be. have a good day!!

Black smoke is an indication that your engine is running too rich. There could be a problem with the timing. Since the starter will crank and you have checked for spark and fuel delivery I would say the only thing left is your timing. If you have never adjusted timing it is not something you can just go out and do. Check your distributor cap and points.

1994 nissan 300zx check engine light is on, car is running rough,

Check the spark plugs and small air lines throughout the engine compartment. One bad air or vacuum line could easily offset the firing in one or more of the pistons.

1997 Nissan pickup seems to be flooding with rough idle & black smoke. Techs troubleshooting computer is not picking up engine computer.

If his scanner won't pick up the computer then the fuse may be blown for the computer or the DLC data link connector fuse may be bad it has two. If the DLC is dead test the three fuses in the cab and the one in the engine compartment on passenger side. if still no Data then you have a bigger problem. The 97 98 changed and They had some problems with the harness Where the plug goes into the fuse inside the cab to the computer.

1993 nissian p/u run rich and it running real rough

If it is a carb engine have the air fuel mixture corrected by adjusting the screws on the carb. Try also adjusting the idling.

For EFI engines see if you can check the Idle Control Solenoid Valve, have it cleaned. You can also check the oxygen sensor if it is working or not
