Just wondering if anyone else has had...or knows anything about this problem. My 92' N/A- Dual plug DIS.
I was trying to diagnose my car which is not running right. & began pulling the spark plug wires from the coils one by one. Strange thing is, that everyone had a spark except the number one on the passenger side(rear coil) Is it supposed to be like that? I tested the wire, & it was good. Confused!

hey guys,i have a engine shakeing problem with my 1992 mustang lx 2.3.my car will run fine for about 20 minutes then engine light comes on and engine starts to shake for a lil bit then run fine again and so on....i put a new fuel pump in,egr valve,spark plug and wires and still does the same thing.im thinking maybe 2 bad injectors i think i might have,but at the same time someone told me if they were really bad then my car wouldnt run fine at all,it would just shake all the way through.then said i might have some kind of electrical problem somewhere,i have no clue...lol could maybe my o2 sensor cause my engine to shake??let me know,thank you

i was having a shaking problem with my 2.3 and it was caused by some bad vacuum lines. so check those before doing anything else.

monkey.... i'd look at the coil ($45 here at autozone and i think a lifetime warranty). if that isn't it, i'd look at the DIS module which is the grey electrical module mounted on the front of the block on the driver's side.

mustang1992...... i don't think it would be a vacuum problem unless it was the vaccuum lines that control the opening of the egr valve (they only have vacuum when it's time for the egr valve to be open). it could be an o2 problem as i had that happen on an old escort i had. the first thing you should do is pull the codes and post them here and that will help everyone here tell you where to hunt.

Sounds like a bad coil to me.
