slow accelleration

Again can be related to the coolant loss/possible head gaskets problem related to your other post. If you have loss of compression then that can cause hesitation as well as other components having problems. If do have to do head gaskets then pay real close attention while doing disassembly and replace other old components that come off during teardown, like egr valve and such. You may also have oxygen sensor and cat conv probs related to head gaskets.
