How do i tune up 1992 diesel dodge pick up
Depends on the mileage on the vehicle which you failed to list.
Hard starting, poor performance, poor fuel mileage.
If you mean, less fuel mileage, then: tune up run rich condition
probably an emission sensor take it in and get tested
The recommended mileage for a tune-up is between 3,000 and 5,000 miles. This ensures that the vehicle is operating at maximum efficiency.
When performance and fuel mileage drops.
I was told by a Mechanic in KY the cost is $649.87. Seems expensive to me. 2.5 hours labor at $186.42, 16 plugs, plug wires, 3 part injector service for $79.99.
When performance and fuel mileage decrease.
Failure to maintain tune up maintenance.
Refer to the owners manual for the recommended frequency of service and tune-ups. Tune-ups are usually scheduled at specific intervals based on mileage.
Bad gas mileage can sometimes be attributed to a vehicle in need of a tune-up. Have your car serviced and see if that improves the gas mileage.
