93 civic lx engine knocks
 

my 93 civic engine knocks/rattles when started then quiets down .And power locks not getting power to switch and fuse is good

The fast idle valve on the throttle body may be stuck closed. Here's how to check:

Attachment 25835

Check whether the WHT/GRN wire to the power lock control unit (behind driver door panel) is getting power. If so, the power lock control unit may be bad.

Attachment 25836

no none of the wires on the control box is getting power.and with the knocking its sounds like its at the the bottom of engine should i still check what u sent me

Adjust the valve clearance if you haven't already. These engines do not have valve lifters, the rocker arms must be adjusted periodically to compensate for wear. Misadjusted valves cause a noisy engine that gets quieter when it warms up. Valve noise is from the top of the engine of course but sometimes it's hard to tell.

Double check whether fuse #6 is blown or loose. Otherwise, the WHT/GRN wire running from the fuse box to the control unit may be broken. Use a multimeter to test continuity of this wire.

I proposed that you check the fast idle valve because I thought that the cold idle might be too low. When the engine is knocking, are the engine idle rpms substantially below spec?

I just found problem i followed the green and white you told me to check and found the wire was burnt out and broke at the plug between door and going in body so i cut wire and spliced bypass the plug now works fine thanx .Im not that advanced in knowing the engine lingo what ur talking about adjusting the rocker arms is that under the valve cover
