Hello! So I got a stock lx with dpfi. Had issues with no power when gas is fully pressed. So I replaced fuel pump, fuel filter, sparks & wires, distributor cap, and finally new tps. So some concerns are that when calibrating with dcv meter its at .5v (perfect) closed throttle but open throttle is 4.10v. Online it says it should be at 4.5 but 4.1 is still acceptable. I drive it around, it goes when gas is pressed 25% but when I'm half way or full throttle rpms drops and engine doesn't accelerate or it jerks power rpms up n down. But when I pump the pedal repeatedly it starts to accelerate. Any help would be nice, cause every mechanic shop around me in Phoenix AZ doesn't do diagnostics on cars that are not obd 1 / under the years 2000s.
