Hello,
1990 Stock ka24e,
When the car is maxed out at 4th gear, everything is normal, and when I shift to 5th, the car will sometimes fuel cutoff at 3k RPM, and it will not go past it, but this is sometimes, It happens with the check engine light on, and it pops codes out that are not in the book, and it is very confusing.
The speed sensor was just changed, and the speedo reads wack readings, sometimes it just goes haywire. sometime it reads max speed, sometime correct speed, and sometimes nothing.

HELP ME!!

If I change the following, would it fix the problem:
Cluster, ECU, AFM,


Please help...

Hell man....you got a bad can o' worms there.
I'm not a expert trouble shooter but it sounds like your ECU is taking a crap. Try replacing that first and see if you still have problems. You should be able to find a 90' ECU easy at a junkyard.

Try this website, largest Nissan junk yard in the nation (I Think).

They should have what you need, fairly cheap. And they ship!!

Good luck, let us know what happens.
