!i have a 2003 ram with 360 gas motor 4/4. my question is it normal for this motor to need a complete tune-up in two years and 20,000 miles?the truck has 89,000 miles on it and was last tuned up at the dealership 2 years ago . plugs wires cap and roto. took it to local garage he changed plus and fixed rough start for about two months now im back to where i started. is this tune-up interval normal or should i get rid of my truck?

 

Whatever is recommended in the service schedule manual.
