Warm starts difficult. have to push down on peddle to start. I replaced the throttle censer. New gas filter, new air filter. New gas pump. Really uses a lot of gas.

    I did and it said the rear banks were not normal even after changing the O2 censors. I assume this means the "Y" pipe needs to be changed.
