Engine warning lite?

[james1300]

03' with 43K. 90 degrees outside air temp today. Accelerating away from light.

Engine droped 2 cylinders, yellow engine warning lite came on for maybe 3 seconds.

Then it went off, and the engine ran fine all the way home, 5 miles.

Full fuel tank. No vacume like noise when I got home and opened the fuel cap.

Ideas's?

Just noticed you have this posted in two places, that's considered bad form around here even if you are trying to get noticed. Expect one of them to get closed.

James,

I am not sure, but you may want to check this link out: https://www.fjrforum.com/forum//index.php?showtopic=22699

It appears you have an intermittent situation with one of your coils. I had a similar situation but not as serious as yours.

Update! I just found a wiring diagram https://fjrpierre.smugmug.com/gallery/63523...116789360/Large

and it appears that the 2 High Voltage Coils (one for #1 & #4)(one for #2 & #3) pins in the Wiring Harness sit right next to each other with no Isolation. Thus any dirt/corrosion causes a leak path(shorting) between the pins causing Irregular/Intermittent poor running conditions. (These 2 pins sit tooooo close to each other with the voltages involved)

Hope this helps and let me know what you find out.
