#1

is it possible for a loose timing chain to cause a engine miss.


#2

Yup.
Why do you ask?


#3

Ditto
And, if the problem is not fixed a.s.a.p., a misfire will seem like a minor problem…


#4

It’s possible, but I don’t think it is a very common cause of most engine misses. Fuel, air, or spark problems would be more likely.
