93 ls400 rpm issues
ok guys my car is acting up when i drive my lexus it doesnt seem to have any power when I step on the gas my car struggles to get over 2 rpms when i step on the gas once it gets to to about 2 rpms my car starts to jerk and its hard for me to pick up speed without a struggle i thought it might be the spark plugs after changing those it seemed better for like a day then seemed to get worse. A friend suggested i might need a new fuel pump, do you guys have any suggestions

I'v never had a problem like that on my 94 ls but on my 99 ls that happened to me and turned out it was the throttle body but like cobalt91 said you need to get the codes before you start replacing things
