really? what problems were you running into? couse the one i have had in for 2 years was from an 87 and i have know other buddies that have done it without experiencing problems.
The problem I had was trying to smog it. My 87 4Runner ran fine with the 85 TPS but I couldn't set the timing correctly. I did some research & found that the 85 TPS is different than the 86-87. I had an 87 TPS & installed it, problem solved.
