rebuild?
 

i bought my 98 z28 last December and i think i just got into a mess the car runs okay with the maf unplugged but idles to high ive been asking around and no one knows whats wrong with it. im pretty sure theres something wrong with the drivetrain also. so i was wondering should i try to rebuild it or should i just sell the car? and if i should rebuild it what do i need and how much will it cost?

or is this a problem i should just try harder to fix?

Sounds like it is in limp in mode might want too check the o2 sensors

SES light on???

What part of the drivetrain do you think is bad? Why?

code says low input on both sensors. low input maf and high input tps like the dang car runs okay not like it should then when i hit the gas to much it just falls flat on its face.

yeah the ses light is on. i think like an axel shaft cause its in the back passenger side.

First thing you need to do is replace both o2's that the codes are calling for they alone can make the car run like crap. Then the maf is most likely dirty go to the store and buy the special crc maf cleaner and follow the directions on the back. This should fix ur motor issues as far as the axle goes take it out and check to see if its bent.

o2 sensors ill replace but the maf is good i put it on my friends 2000 z28 and it runs fine. yeah im going to check the axle out to see if its bent.

if you leave the maf unplugged it is going to run like crap at WOT. If the TPS is bad that could cause it also to run really funny. If you have acess to a scanner use it to make a graph of the TPS as you open and close the throttle. If any bumps or hiccups, then the sensor is bad and replace it. Any one of those sensors being bad will make the car run like dog poop. If you fix your sensor problems the car is worth a lot more.

borrow the TPS sensor from your friends car and put it on yours to see if that is the problem.

just did that and its not that im thinking i should replace the o2 sensors and take it from there do yall think doing that willl make it run better

Yes..

thanks man i appreciate it. i only need the front to right?

correct, the back two are for your cats.
