I brought my work van there for a complete tune-up costing $446.54
It ran worse when I picked it up.
Took it back the next day and they said it needed a distributor.
Got a second opinion and it turns out they didn't secure the plug wires properly and one burnt up on the manifold so they put one of the old wires back on the next day and then tried to sell me on the distributor being the problem and wanted to charge me another approx. $450 for parts and labor for it.
Don't use this Precision Tune because they are liars and cheats.
