513EM1

So recently I have noticed some hesitation while accelerating. I had some idling problems a few months or so ago. Replaced IACV, TPS, O2 sensor, plugs and wires.

As I hold my foot on the gas, I can feel when the car hesitates, then it doesnt, then hesitates again, like a sudden power loss. What could it be now? Does the TPS need re adjusted?

Help appreciated, Thanks

What is the TPS output voltage when the throttle is closed?

It should be .49V exactly. Adjust it to that voltage, then see how it runs.

Thanks, Ill do that and let ya know how it goes

Okay. So without checking the TPS yet. I saw that my over flow tank was completely empty. I filled it up, and the problem is gone.

Does this make sense or could the hesitation have nothing to do with that?

Directly? No connection....but that begs the question:

Is the RADIATOR low?
That may have something to do with it, since fast idle valves operation depends on coolant circulation.

Nope. The radiator was full. But right when I filled the overflow up, I noticed a difference as soon as I took off. Pulled like it should

If that's the case, then your observation is nothing more than a coincidence.

I'd say check the intake pipe. make sure there's good air flow.

Maybe fuel pump or fuel filter...
