You guys are AWESOME!

Thank you all so much for your time & effort. You all already made me look like bloody Nostradamus to my co-workers when the CPS failed during my morning commute and I had spare one & tools in the car already.

One last question, please.
Do you find it worth changing other relays in the RCM at the same time as the seconday air item, do any of the others wear out as quickly & cause issues? I don't imagine the horn or traction control relays get used much, but what about the fuel pump & engine control?
