My 1986 4 Runner starts fine and runs great for about 10 miles. Then I get a loss in power. I can downshift and keep going. Then it will happen again in a short distance. Same thing. Also, when this started I noticed some exhaust smoke coming out the rear. This is a new motor, and even before that I never had an exhaust problem at all. The last time I drove it, the smoke came up inside the 4 Runner beside the drivers and passenger seats when I was losing power. This scared me so I just had it towed home. It had acted like it was running out of gas, too, but I had just put gas in it and replaced the whole fuel system not long ago. I was told it was probably the catalytic converter. Is this a probability?
