Default Engine Code 73

UPDATE: I checked the ECU, and the code that it's throwing out is 73 (Cylinder 3 misfire or random misfire), but my engine is running fine after two starts...anyone know what can cause this situation? I heard it could be anything from the spark plug, to the wires, to the distributor...HELP!

Original Message:

This morning when I started my car (97 DX), it was shaking pretty bad, and then the check engine light kicked in when the idle returned to normal. What the heck could it be? It's never had this problem before, and I got about 69K miles on it...anyone have any ideas? I had to take the car to work and it would seem that everything was running fine. I even shut down the car and started it again, but I didn't get any repeat...I only have a short ram intake on the car too..

um, start by replacing the spark plugs, wire, and distro. (did you check the gap on the #3 plug? also check for corrosion/goo/chemicals of any sort -- do this first.)

under 20 bucks

you should be able to do all three for around a 100 or less.

Wow, that was cheaper than I had imagined...I'll look into it...I'm guessing it's the spark plug - I just hope nothing else is causing the problem. I'll reset the ecu afterwards and see if the problem has cleared itself...thanks again for the help man!

werd, the spark on its own should be like $2-10 depending on what you get. (lol, can you even get a spark plug for 10 bucks?)

for 20 you'll just be replacing the cap and rotor on the dist. Basically a rebuild on it. Anyway, take your cap off and see if the polls are all nastied up. If they are, get a new one for 8 bucks. But like everyone's said, check the plug and wire first.

oops, sorry to not be specific. cap and rotor on a distro is general maintenance and cheap, distro itself can be $100+
