my calais drives fine then suddenly lose acceleration no matter how much gas i give…
91 olds running on two cylinders i have changed the plugs and wires the coils and the coil housing what else could it be.
Could be a few things that might cause this issue.
- Loss of Compression – possible blown head gasket or valve damage
- Loss of injector pulse or stuck injector if equipped
- Spark plugs damaged
- Plug wires damaged
- Wiring Harness damage
