Car will run at relatively low speeds if you feather the gas.....Once you mash the throttle it falls on its face...Idle is fine..No check engine light ....

91 Z w 510 package w cams ..Sec deleted..Pumps were swapped 5,000 miles ago...Fuel filter about 15,000 miles ago..Car has 57,000 miles..

Bad gas ? Don't think that's it....Cars driven regularly ....Put some fresh gas yesterday...Same thing....No backfire just hesitant and nothing when you lean into the throttle...

Anyone ?
