Engine Performance problem
2002 Toyota Corolla 4 cyl Two Wheel Drive Automatic 166000 miles
I performed vaucuum chek with steady ready of 8 hg;
and after increase throttle the needle would decrease to zero. Does this indicate leaking intake manifold or throttle body leak? All vacuum hoses appear in good shape and couln't find any leaks. When I tried eng compression chek the needle on gage wouldnt hold any readings any suddenly decrease to zero. Could I have faulty gage?
i would appreciate your help
