[urq] ** SOS - Stranded!! ** Ignition Problem?

[W. Stedman]

What about the white plug behind the key in the ignition?
Mine has failed a few times and there has been a different problem every
time it failed. 




Objet : [urq] ** SOS - Stranded!! ** Ignition Problem?


So, I'm on my way to Mid-Ohio, enjoying the cooler weather and the urq...
The problem started as a very occasional and brief cut of power while under
partial boost (5-10 psi). It was just like a quick hiccup, then everything
was fine again. Then it progressively got more frequent and pronounced. It
would idle OK and seemed to smooth out under full boost, but part throttle
on or off boost was bucking wildly. For a time I could downshift to 4th and
run about 4200 rpm with fewer troubles, but even that eventually got bad. It
got to the point that full boost wouldn't even work right, and idle would
sometimes be bad, even stalled a few times. 

Here's all the stuff that didn't fix it: 
- Parked for about an hour while I had dinner--problem returned almost
immediately after restart. 
- Pulled cap, it and rotor look fine, as do wires. Haven't checked the plugs
yet. 
- Unplugged O2, still bucked but there seemed to be more unburnt fuel, lots
of backfire pops accompanied by smoke. 
- It hasn't had any starting issues all day. 
It got so bad that it was undrivable on the interstate. I parked it and have
continued on (luckily, the fair Elizabeth was following in her Mini). 

So, it doesn't seem isolated to a cylinder, so I'm thinking the coil's
dying, or maybe the ignition module? Am I overlooking anything? Any BTDT or
advice for me? 

What are my chances of scoring a coil on a holiday weekend? Is this coil
shared with other I5s or is it special to the urq? 

I'm headed for the hotel right now and will return tomorrow morning to see
what can be done. 

Thanks in advance, 
Eric R.
