Last couple of days (and not consistently, more randomly), I've noticed that while accelerating at around 20mph, 40mph, and 60mph the engine speed drops a bit and goes back up. The weird thing is it only does it in regular mode, not in sport mode. I was wondering if I should look at some ignition issue (I was thinking spark plug wires) or the tranny. I've noticed it only happens at night, regardless of the engine being warm or cold. Never had it happen during the day. __________________ -1987 5 spd N/A with TEMS: low miles!
