I have a 97 Trooper that rattles terribly.
I have tried premium gas, gas additives, synthetic oil, thinner oil, and nothing seems to work.
Is there anyone that might know what the problem is? ... and possibly a trick or solution?
My engine rattle a lot too. But then I change all the vacuum hose, the it runs smooth again.
Is it a carburated engine? Is so, trying to look for the vacuum leak
