    Replaced bulbs on my 360 with LED bulbs meant for a 430, now when I start the vehicle, it starts with low grumble, then gets to its usual loudness... would changing the bulbs cause this?

    Sounds like it's starting on one bank? On cold start, try waiting for 20 seconds or so with the Check OK message up. This should allow time for the immo signal to authorise the second bank

    Sierra, tried your recommendation, it still hesitated and choked a little, then growled like normal. I’ll try to record it to provide a better idea of what it’s doing. Thanks all for the assist...

    LED's use so much less power, about 1/8th of incandescents, that it can throw off automotive ECU's (the current draw is so much lower that an ECU can think a light is out for example). So, in theory, it's possible it could have an effect, but usually you would get some warning lights if an ECU was confused. I can't think of anything in engine management that would have dependency on lighting status, so it seems unlikely. On the other hand, cars are so complex these days with interaction of various sensors, that I wouldn't totally dismiss the possibility. If you can't find any other cause, it's probably worth swapping back the old bulbs to see if that fixes it.
