Bonneville hesitation.

Post by CHRIS904 »

Hello got my 98 bonneville with 37k original miles. Car has sat for years anyways. Had to change a cam sensor and altenator. I got an issue we're when turning at a stop sign or red light the car has what feels like a mis fire. I get no cel or anything. The car runs great at Idle and high speed. Going to change fuel and air filter tonight. Any ideas?

You may need to check your ignition wire. coils and or spark plugs. Do you have any P0300s codes?

Pull the codes even with no CEL to see if there's anything pending.

I think it has something to do with fuel sloshing in the tank. It doesn't do it when the tanks fuel once you get to half a tank it will. I'm not too worried about it when the fuel pump fails I'll find out then.
