help. i have a 93 honda civic. my a/c went south and had it repaired. new fan switch and fan assembly unit. A/C works great, however, when A/C is on and I have contstant accelleration, (even with cruise control) the engine speeds up and down continually. It does not happen however, when A/C is not on? Can that still be the VSS, (vehicle speed sensor) or would it cause the surge regardless if the A/C was in use or not. Appreciate any advise.
