What the timing set at on a 1991 ford ranger 2.9 liter?

There isn't a single "timing setting" for a 1991 Ford Ranger 2.9L engine in the way that, say, a distributor with a rotating plate has a degree setting. The 2.9L Cologne V6 uses a timing chain, not a belt, and the timing is non-adjustable by the user. The timing is factory-set and determined by the chain's sprockets and the camshaft's position relative to the crankshaft.

If you're having timing-related issues, it's unlikely to be a setting that needs adjusting. Instead, you'll likely need to investigate problems such as:

* A stretched or worn timing chain: This is the most common cause of timing issues in these engines, leading to poor performance or even engine damage.

* A damaged or incorrectly installed timing chain: Incorrect installation during a repair would be a significant problem.

* Other engine issues mistaken for timing problems: Problems with the fuel system, ignition system, or other components can mimic timing issues.

If your Ranger is experiencing performance issues, it's best to take it to a mechanic for diagnosis. They will have the proper tools and expertise to diagnose the root cause of the problem, which is almost certainly *not* an adjustable timing setting.
