My montero has lost power. Ive had it in 2 different shops and the test they have ran has came back that everything is good. The first shop said it was the catalytic converter so paid to have that done an it wasnt it. 2nd shop did a compression check an replaced the fuel throtlle sensor and still didnt fix the problem. They are clueless an said they have never had a car they cannot fix of figure out what the problem is. Please help.

the only other thing I could say is to do a compression check to see what it is. it may be low causing the power loss. what was the compression check number wise also maybe pull valve cover see if any cam wear etc.
