Hey everyone. I have a 1991 sw21 MR2 manual transmission and every morning, it starts up fine but as soon as I put it in reverse, the rpms drop to where it almost dies. After it does this I put it back and neutral and then reverse to try and replicate the problem but it doesn't do it again. Even after I get off work and the car sat for about eleven hours, it still won't have the problem until morning. Does anyone have an idea of what it could be?
