the check engine come on...i pull the code and its my tps senser

so today i was replacing it...and its a simple job tht takes abut 20 mins...its just two bolts on top and one undrer the throttle body....so thw whole throttle body must be lefted to get to this 3rd bolt...

i hooked everything up and put all the vac lines back and i checked to make sure everything was good...i then started the car and it revs up and down...as it warms up its good...but as soon as u step on the gas it revs up and down.....until i get over 3000 rpm...so whats the problem....

its a 89 na bone stock

thanks

 

did you adjust the tps to be in spec?? check for flat spots and or spikes in the reading?

 

does it feel like a fuel cut or just revs gradually up and down?

yeah it feels like fuel cut
