Fix Engine hesitation stalling on Astro Safari Van
Shops are reporting a problem with engine hesitation stalling on Astro Safari Van. They’re all the symptoms of a bad spark plug/wire/coil. But those components check out. The worst part is that the problem is intermittent. If have these engine hesitation stalling problems and you’ve checked out the plugs and wires on your vehicle, head right for the wire going to the coil primary. Apparently, the A/C line can rub against this wire causing it to fray inside the insulation. The remaining strands cannot carry enough current to saturate the coil and the problem reveals itself in these drivability issues. Run your finger along the insulation and if you feel any dip or thin spot, strip the insulation away and check for frayed strands.
