Hi all,
I have an 03' sedan with 103k miles and everytime I let off the throttle when I'm driving at lower speeds i feel the car give a slight lurch as if it was shifting hard, the revs dip as this happens and goes back to normal as I slow down. I just got the cam sensors, and throttle body replaced. I was wondering if this was normal or if this is a symptom that most of you guys out there have had before, I suspect that it has to do with the ATF needing to be changed and I don't now when the previous owner changed it last but any information or help would be appreciated.

 

Since your throttle body was replaced, you may want to go thru the reset procedure. Here is the procedure I used to reset my throttle position.

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Confirm that the accelerator pedal is fully released, then turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.

Good luck.

 

that's what i had in mind when the throttle body was being replaced but my mechanic had reprogrammed everything to work..i suspect it has something to do with the transmission
