1997 Nissan hard body pick-up 2.4 won't idle and blows smoke

I have a 1997 Nissan hard body pick-up 2.4. When temps are cold, engine runs fine. When temps rise, the truck won't idle and it blows black smoke. I have changed the mass air flow sensor, but it still won't idle. Are there any other solutions to this problem?

Truck runs rough and will not pick up speed also abs light came on, idles up and down.

Do you smell a burning smell? or smoke from the wheels? (brakes) You may be running with the brakes activated due to ABS problem (no pickup) and your accelerating & the PC is lowering the idle. (erratic idle?) Or a idle speed control or throttle positioning sensor? Get that one checked out. It could be as simple as a vacuum leak. That's a hard one to call without checking it out. Good luck

My 1996 nissan wingroad runs and pulls beatifully when cold but when warm hesitates as if flooding or starving when pulling from below 2200 revs especially when accelerating out of a corner.any...

common fault in this vehicle is air flow meter and temp sensor, if temp sensor fault normally will blow black smoke at the tail pie, air flow meter will have symptoms as you described.

1997 Nissan hard body pick-up 2.4 won't idle and blows black smok

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.

Heater bows cold when idling

You need to bleed the cooling system.
To do this park on level ground, when cold remove coolant filler cap, start engine and leave to idle.
Have plenty of warm/hot water available, when engine reaches operating temp it may appear to boil over so keep away from coolant filler, top up with warm/hot water and wait as it may bubble over a few times before settling.
Replace cap and hopefully back to normal, Remember your Anti Freeze?
Good luck,
