Jerks On Initial Acceleration


Gebo

Recommended Posts

OK, I've had my '98 since '01. Best Car I have ever had! One issue I have always dealt with is this. When I start out from a complete stop, I mash the accelerator and not matter how I try, it will jerk the car. It seem I can't depress the pedal gently enough to get a smooth takeoff. My Daughter's IS300-no problem. My Wife's GS300-no problem. My LX470-no problem. My LS400 will jerk your neck it's is so bad. Any ideas?

Your car has been doing this for eight years and you have never had the problem diagnosed? :whistles:

I might start at the accelerator pedal and have the PPS and TPS checked.

Yeah, I didn't know any different 8 years ago and I have just gotten used to it. It's only when someone else is with me do I "notice" it. How do I check PPS and TPS?

How do I check PPS and TPS?

With an ohmmeter after disconnecting them.

PPS: Resistance between terminals VC and E2 should be 1.64 - 3.28 kilohms at 20° C (68° F)

TPS: Resistance between terminals VC and E2 should be 1.25 - 2.35 kilohms at 20° C (68° F)

OK. Where is the PPS and the TPS? I can do the ohms.
