All was good until hot summer weather arrived.
2nd time I had problems, clutch pedal spongy, slow to return, and then I had to pull pedal up with foot to get it to return. 90° plus outside temp, & I was in a traffic back-up from beach.
Made it home. Checked clutch fluid level, it was good, but fluid noticeably darker in color.
Note I do have aftermarket 3" dual exhaust (header back). I think a lot of heat is transferred from them.
Car sat in garage 2 days. I went for drive and clutch was fine, for awhile. But after about 40+ minutes of driving, clutch problem arrouse again.
If I "granny shift" car, with no high rpm, I can get by longer, but that defeats purpose of why I bought the car.
I'm considering the CSC elimination kit, but not sure of fit with after market exhausts.
