91' loss of power give me some Ideas!!
Hey yall I have a 91 4x4 Sr5 that has lost power. Engine runs great its only about 3 years old, but now it wont pull a hill for crap. flat ground does pretty good unless you really try to get on it. then its like you are dragging a piano or something. Need some ideas on what could be the problem.

You might have a vacuum leak. There are lots of DIY options like using a propane torch and listening for the idle but I recommend a smoke test. One of the Midas shops near me had a smoker diagnostic machine. Turned out I had some minor leaks that were easily fixed with some new hoses. This should also find any exhaust leaks you may have, those can also really hurt your power.
