Well, possibly a little out of your way, but York Dodge up in Prescott didn't even hesitate to replace my lp last fall. All I said to the service manager and the mechanic was that it was starting hard and idling rough, and I assumed that I was having problems with the fuel pump... sure as ****, he put the test gauge on and told me he couldn't get a steady reading at idle, so they threw a new one on it free of charge. BTW, yes, I had my Comp and gauges at the time (minus the FP gauge that I now have installed). They either never checked, or didn't care about the Comp, as I never took it off and the wire is clearly pierced...
Just a thought if you've got the time to drive up.
Don't know his last name, but the service manager I have talked to all the times I've been in there is Joe... he's kind of a huskier guy, but has done me good on two different warranty occasions, but York itself is still a *tealer in my book, cause they want $52 for a fuel filter and almost $20 for an oil filter... thank god for Geno's.
