Recently I noticed the engine misses a beat when accelerating onto a highway or climbing hills. Usually only one beat. This was probably discussed earlier but could not find thread. I know there could be a lot of reasons. Changed the fuel filter, was dirty, but did not solve the problem. What should the next step or steps be? Ignition wires, plugs......?
It's has a 3400 cc motor with O/D. transmission and 320,000 Km. on it.
