got her back today.
purrs like a sleeping lion. night & day difference. pulls harder & more responsive, which is probably a combo of the EB getting proper timing again & throttle reset my guess.
took about a week.
they replaced the water pump as well while they were in there, as a precaution - i flagged it over & over & reminded them that it’s covered under warranty if it fails so might as well do it now if you can see what you need to see to make that happen. & they did.
replaced the front two shocks under warranty, will replace them next go round (in god knows how few miles from now !)
NOTE: for those who are going to do the phaser.... when resetting the body down once complete, the tech screwed up & didn’t notice that he had pushed the gas nozzle down out of place. went to fill it up, & the 60iq gas attendant proceeded to fill up my left rear wheel with premium (because there was no downspout receiver, just a hole.) dealer promptly put me in a Yukon (yuck-on!) which gave me a great comparison that lasted all of a few hours before i insisted on a different vehicle. yes it was that bad, IMO. i would rather have a tempermental expy over one of those any day.
anyhow, my love hate relationship with this vehicle continues. what was that phrase... buy a ferrari & be prepared for the headaches? well this is my ferrari then, i’ll take it... the good is clearly worth the bad.
