i hope someone can help me. ive searched the postings and couldnt find the answer to myy question.
I just bought a 95 hardbody, 4 cyl. 4x4 5 speed for dirt cheap. when driving once you get up to about 3500 rpm it totaly falls on its face, looses all power and pics back up again around 2500. truck is slow to accelerate (im used to driving my turned up 7.3 powerstroke so might just be im used to a lot of torque ) also if its just idling and you mash the pedal it stumbles then pics up but again 3500 is all shes got.

i went ahead and replaced the fuel filter bc it looked pretty old and cleaned up the spark plugs and replaced the wires. i have not checked timing or changed distributor cap/ button. so what gives? i hope someone can help. ive always had good luck with my past nissans and want to continue that

I've seen a cracked ignition coil cause this; I've seen a bad or dirty MAF cause this.

If you check the ignition coil, make sure you inspect it very carefully as the cracks can be hard to see. Good luck.

cool thanks! nice build thread btw

bought a can of maf cleaner, removed maf, cleaned it up and it runs amazing!

Glad it was so simple! And thanks!
