Default 91 Olds 98 Idle Problem
I've been having a problem at idle with my 91 Olds 98 3800 Engine (watch video)...... I have replaced the plugs, wires, coil pack, module, temperature sensor and it is still idling rough..... any more ideas of what to check? https://photos.google.com/share/AF1Q...5VMzdibzRiMUlB
