Hi guys,
just wondering if anyone can help.
I've recently acquired what seems to be a lovely misfire.
The cars seems to run perfectly well in every way possible, ides fine, drives fine etc, unless under full boost. It almost sounds as if traction control has interfered, although no DSTC light flashing on the dash. AWD is definately still working, so it's not just a simple case of wheel spin etc.
I have had it hooked up to the laptop to no avail, no codes stored out of the ordinary, just a code that was set by having no cat.
I suppose a bit of background on the car would help;
It's on an 03 place with 127k on the clock.
It has been remapped for the last 50 to 60k, and also has a 2.5 stainless exhaust with a decat.
I did recently replace a coil on cylinder 2, and that fixed a different misfire, although this on sounds completely different.
I have bought another new coil, and checked resistances of all coils, and compared then to the brand new one, and all were found to be very similar.
My next step is to swap it from cylinder to cylinder, and take it for a test drive until it either fixes the problem, or all coils on all cylinders have been eliminated.
Any help or ideas of where to look and what to look for would be appreciated.
