I have searched the forum and did not find a thread with this particular problem. I have a 98 LX with stock driveline and exhaust. When I start the engine it fires up then the rpm's dip, then bounce back up. If I try to shift into gear during the dip the engine dies. If I wait to shift until after the dip the engine runs and drives fine. What could be causing the dip in rpm's? Or is this normal?
