What does your temp gauge look like??? Could be a bad thermostat... I had that problem too.

the temperature guage is fine its a little under the half mark!

I have the same exact problem recently with my 92 MR2 turbo. Can't figure it out??. Everything was up to par until I noticed my boost only goes to 7psi instead of 10psi. I run 10psi when my car wants to not when I want it to..
