Go to (You'll have to register) Download the manual for a 92-95 Honda Civic because the manual for 91 CRX doesn't show the EGR valve. After download go to the section that says "fuel and emissions"--The Egr section is on pages 11-135 thru 11-139. One difference between the Civic and CRX is that the 2P connector is 2 wires on the civic and 4 on the CRX. The extra 2 wires on that plugin go the fuel injection system componet which is also unfer the control box. The 2 wires(on the 4 wire plugin) that go to the EGR control solenoid vale are ORN/BLU and BLK/YEL-----Hope this helps

Check the hydraulic fluid level for the clutch master cylinder, it may be empty. If it is empty you can fill it with DOT 3 brake fluid. This may temporarily fix the problem but you still have a leak in the system.
