1991 CRX, real bad lack of power surges very dadly

The Si was about 108hp and 100tq

engine missing, poor idle, bad gas millage lack of power, but really need motor size to pin it down and model

the firing order for your 91 crx should be 1, 3, 4 and 2. You need to identify where the rotor points to when cylinder 1 is at top dead center.
Cylinder number 1 is the one closest to the accessory belts (alternator, power steering , etc, hope this helps.

Try tracing the wires and looking for a worn spot in insulation that is grounding out, its a royal pain but might be the only solution, use wire prob and test areas where inaccessible. good luck

I hope this helps, it all I could find.

You didn't mention how old the battery is but it could be that it has reached the the end of it's life. Just about anyplace that sells batteries will test it for free. As for a draw, it is possible for any number of things to run down the battery overnight including the diodes inside the alternator. (yes it can make a charge and still have a bad diode) Even the battery itself can be internally shorted. To determine if something in the cars electrical system is causing the draw, the next time you park it disconnect the battery, if it is dead the next day...viola' you have a bad battery. If not you have some more work to do. Try step one and if that doesn't get you anywhere, get back on here and we can go over what to do next.

most likely it is on the passenger side under the dash

you'll need to take the gauge cluster out and disassemble it. then take off the pointers making sure to note where they're pointing to. then apply the new face. and wire power and ground. put the pointers back on and reassemble.

check the wire going to the clutch or tranny switch for power from the ignition switch if there is no power there the ignition switch needs replace

you would have to check the axle is the same
