I posted about a month ago about a hesitation problem I was having with my 2002 L, 2.5, 5spd MT. Initially it was hesitating on light acceleration between 1300-1800 rpm, intermitantly. I didn't manage to find the problem, and the hesitation is somewhat worse, from 1000 to 2200 rpm now, sometimes worse than others. The car starts right up, idles smoothly, pulls strong above 2400 rpm, and is steady at speed. The car has 73600 miles, and gets 23-24 mpg in town.
The plugs have 14k miles on them, and appear normal, (light tan).
I inspected the coil with a multimeter, and this is what I found...
The primary side between terminal 1 and 2, and 2 and 4 should read .73 OHM +/- 10%, my reading for both was nothing...open circuit.
The secondary side should read 12.8 OHM +/- 15% between the #1 and #2 cylinder terminals, and the #3 and #4 terminals...I got 13.98, and 13.70 respectively, a little high, but within spec.
The shortest spark plug wire should read a mimimum of 6.24 OHM, I got < 4OHM.
I thought this all seemed off, so I checked again, then checked again with a different multi-meter, and got the same results all over.
The plug wires aren't OEM, the terminal on the #1 of the original set broke at 33000 miles. I was out of warranty as far as time goes, so I replaced them with a set from NAPA, (Belden max).
Questions...Is the coil fried, or did I read it wrong? Could it work with broken or burned out primarys? Did the low resistance in the spark plug wires damage the coil? Should I find a new one before I end up stranded beside the road? Is this even the cause of the hesitation problem in the first place?
Any ideas?
