SES...Error code found

[JEFNLSA]

The only code I pulled was a PO 300 which is random multiple cylinder misfire.
Any guesses on what would cause that and, better yet, what would resolve it? New plugs and wires 5000 mi ago. Car runs fine...I'm baffled.:confused

My friend may have got that error on his 94 after we replaced the wires and used some colored aluminum wire looms. (Red anadized Moroso)

I dont rember the PO 300 but the random multiple cylinder misfire sounds very familiar. Is any of the plastic insulation on the factory wire looms cracked off?

Reset the ECM and see if the code comes back, first.

Yeah...maybe it was just that. A "random misfire". It's been reset so I guess I'll find out.

Thx

I'm also going to inspect the plug wires and looms....who knows?
