MPH Gauge went out

[Williomi]

I have a 91 crx si. On the way to lunch inbetween classes i noticed my mph gauge isn't moving. It was fine in the morning. After a few minutes the check engine light came out. I counted 17 blinks which would be a fuel injector. But somewhere i read 19 is the Vehical Speed Sensor. When it is cold outside in the morning. The first start up takes a few seconds to turn over and wants to idle around 2000 rpms. The rest of the day it'll drop to about 1000 rpms and I will have no problems with it turning over right away. Could this possibly be a bad fuel injector. Also I belive they are the orginals and i have about 115000 on it should they be changed thanks for you help

Fuel injectors could be bad but I'd be certain about the code first. Also, you have an Si with a FICV (fast idle control valve) so don't worry about the high rpm upon cold start up. You could mess with the idle screw and trottle cable if you want it a little lower. As for your speedo gauge not working, make sure the cable is in your tranny tight. Also make sure it's plugged into the back of your gauge tight.

Yup the car is def throwing 17 blinks for fueld injector problem

everytime i start the car up it takes about 1-4 min to throw the engine light again

speedo problem wouldnt have anything to do with your fuel injector, its cable driven. If its not working it should also be throwing a code for the VSS. Pull the cable out of your tranny, its by the rear mount area once you have it out, pull on the cable itself, if it pulls from the housing you have a broken cable. They are like $25 bucks from the parts store and are really easy to replace.

code 17 is vss code take out the gauge cluster and see if the speedo cable is plugged in all the way i got a 91 4 door and i put ls integra gauge cluster in it and when my cable comes out the engine light comes on and its 17 blinks which is vss but when i plug the speedo cable in the cluster it goes off so just take ur cluster out and plugg that cable in and the light should go off

Thanks for your help i just got checked what the codes are on this site and they said 17 was the vss as well. So i must have been looking at a different generation or something thanks for backing that up
