When I bought my 94 SR the people before me had been trying to troubleshoot it for a while cause it was in Limp mode. I found that the Crank bolt had loosened and the crank sensor wheel had broken free of its locating pins which I think put it in limp mode. If your Monty is indeed in Limp mode might want to check some of your sensors.
