Question about 1997 Nissan Pickup
In morning temps, truck runs fine, but in higher temps, it won't idle and it blows black smoke. I replaced the mass air flow sensor, which didn't help at all with the idling. Are there any other solutions to this problem?
If its not the mass air flow sensor then you also have to check the timing belt or maybe you might have a vacume hose off or cracked or a passage is blocked or it could be your throttle body intake tube could be loose,off or cracked. then after checking all of the above replace wire harnest for the spark plugs and spark plugs and it should fix your problem.

Hi, the most common issue here will be with a faulty Fuel injector pressure regulator. it could be Mis-adjusted or, faulty. replace this regulator asap. here are some other uncommon check points that i would inspect as well below just to be safe.
1. Coolant tempreture sensor- this sensor may be disconnected or faulty. this may be the cuase of the high tmp as well.
2. Canister Purge Valve- this valve may be fualty. inspect thoroughly.
