I checked my truck in with a check engine light on and a slight miss on occasional acceleration. The tech diagonosed the problem as bad intake manifold gasget that caused cylender 5 to misfire after the tech changed the gasget there was still a misfire on cylinder 5 he then found a loose plug wire on cylinder 5 which he corrected and fixed the misfire. I picked up the vehicle and started home and the engine light came on so I called Dawn Bray and she said to bring the truck back in morning which iI did Dawn requested another $500. deposit which I refused as I assumed it was a continuation of the same repair. So I refused the new deposit and am out $905 to tighten a spark plug wire and still driving a vehicle with engine light on.
