alright guys, here just a half hour or so ago I was on my way home from my friends and on the way home while I was driving the car all of a sudden made a shudder and started running VERY ROUGH. It wont idle or rev smoothly, it kind of feels as if it is missing out, and you can feel it shimmy quite a bit while sitting at idle. Its a '93 fastback (so ka24de), with no engine mods.

what are all the things I should look at?

plugs/wires?
injectors?
timing?

ALL help would be GREATLY appreciated.

Thanks in advance for the help.

This could be just my opinion,but I'd say to check out your timing,definitely check out your timing,I doubt it would be your plugs/wires,but if they haven't been replaced in a long time,as in STOCKERS than you might want to go ahead and replace those.

Sorry,I don't know what to say other than that,I'm just learning about S13s myself....I used to be a muscle car head..

Check the plug on the MAS. Right after the airbox on the intake tube. (The only thing metal on the airbox side) It will have a harness pluged into it. The little c-clip thing that holds the plug on was not there when I bought the car. Shortly there after I had the same problem. I just zip-tied it and haven't had a problem yet.
Just something to check.

If its not any of the above, chec your coolant temp sensor. mine did the same thing, i chaned the sensor, its been flawless ever since.
