I have a 1986 Nissan D21 pickup 2.4l. It is currently running like crap. I have replaced the injectors mass air flow meter catalitic converter spark plugs cap and rotor.
The car will run fine for a bit then will
gradually get worse. Some times it
acts like it is starving for fuel but
smells rich. I starts to stumble at idle
and at times dies. Almost impossible
to start once this happens.
Napz 24 engine?
8 plug bastard.
Yes that bastard.
Check the cap and rotor it has twin center contacts, pick up unit failure is common and gets worse under warm conditions, when it dies check for spark. No spark is pick up in distributor, cap and rotor are common. I hate napz engines.
Also if you wanna have a really good set up toss the napz head and and put a 2.4 twin cam off a 200sx and use your intake and carb. Be sure to verify cooling ports in the head and block correspond.
Pull the codes. It sounds like the ECU is in limp mode. This thread goes into detail: www.infamousnissan.com/forum/showthread.php?t=31527
