Chevy K1500 Ignition Timing

Q. Would it be wise to have the timing checked and adjusted if necessary? 1995 Chevy K1500 4x4, 5.7 liter TBI 173,000 miles. I don't know when the last time it was done, and I'm sure that an engine with that much mileage would benefit from a timing adjustment, but I'm also afraid that if I mess with the timing it will throw the whole engine out of whack.

Thanks again Vince.

A. It can't hurt to check it. Write down where it is set if it's off. Then put it to spec and drive it. If it runs worse you can always set it back to where it was. Just remember to read the tune up label as to how to set.
