My 87 9kt all of a sudden developed a rough idle and hesitation during accelleration. Seems to smooth out at highway speeds but I know it's not healthy. Like it's not running on all 4. The CHECK RADIATOR light intermittantly will be on when it's doing this too but the coolant level is okay. I'm also hearing a new slight mechanical engine noise at idle but that could just be minor slack in the timing chain slapping due to the roughness. Could the harmonic balancer have walked? Any ideas?
The car has 207k on it and I drive it hard (sees 100mph daily, like to shift at 5800) but I do maintain it well. Thanks
Yesterday I posted about a cooling fan circuit issue. That was wrong. I thought I was overheating because I saw the light, temp gauge doesn't work and rough idle led me to believe I was running hot.
