Hi Sean, I just wanted to ask a question. You said in an earlier post that when you checked voltage at the battery at idle was 14.0v, and with accessories on went down to 12.5v, did you have the battery and alternator tested? It shouldn't be below 14.2v even with lights, wipers,ac on. I've seen many times where the positive cable coming off the alternator fails, causing charge problems, especially since you're in Texas. I'm from Houston myself, the heat takes it's toll on batteries among other things, even though it may just be the battery itself. Just wanted to point that out with your charging voltage, Jags are very sensitive to voltage drop. Just something else to keep an eye on.

Thanks Rich, I have a trickle charge option on my charger, which I will use when storing the car ....... the days are warm enough now so top down and hit the road ..... though I will be getting a new ride this year but haven't decided what that will be.

Update ....... all's well and my XK8 is still running great, though I haven't put that many miles on it since the ECM repair ..... thanks again to everyone who passed on their helpful suggestions and solutions.
