Van misfiring. First diagnosed as just a misfire, service performed, roblem persisted. Returned to repair shop for redo, am now told misfire caused by bad valves, needs complete job to fix.
Are misfiring cylinders covered under any recalls from company?
What would/should be the average cost of a valve job?
Other options?

Thank you

 

You can search the NTSB website for open recalls on your vehicle.
Cost depends on location and labor rates. Call around to a few places and get some estimates.
