5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
My 2005 4 cylinder camry has been getting power issue.
I notice that when I step on the gas lightly, the car doesn't want to move but if I step on it a little more, it jerks forward and feels like it over rev'ed it.
Does anybody know or understand the issue that I have? If so what is the problem or what do you think is the problem so I can fix it myself or take it to a pro.
When I step on the gas 1/4 of the way, the car feels like it doesn't want to move or feels heavy/slow
When I step on another 1/4 of the way, the car totally jerks, revs and go.
It feels as if it a miss shift, or something is wrong with the clutch.
I am driving an Automatic btw, I4, 40k miles on it.
I will try to remove the battery wire.

MIL = Malfunction Indicator Lamp (check engine light)
You are feeling your car downshift into a lower gear. The lower gear makes the engine RPM's increase. That's normal. Sometimes the cars adaptive memory seems to not blend well with the persons driving habits. I've seen this happen MANY times. Resetting the ECM works great if that's the problem.
does it feel like a hesitation? you may be feeling an adverse sensation of the drive by wire (DBW) throttle, which uses a computer controlled throttle instead of a traditional throttle controlled cable....this system causes a lag time in between you hitting the throttle and the car responding, thus the feeling of hesitation and then a jerking in a surge of power....there is no cure for this, as its just how the car is
if in fact it has something to do with the car and your driving style, id disconnect the battery negative (-) terminal and let it sit for 10 minutes to reset the ECU, and then drive it and let the car relearn according to your driving style. youll be real suprised how effective simply resetting the ECU is and the problems it solves
Mine did that too when I first got it. It seems to be ok now, but I think it's a combination of the computer leaning the way I drive or me learning to drive with the delay in throttle response. Now I push on the gas just a bit until the engine responds then lay on more pedal to get going. Takes a bit of getting used to. I may also try resetting the ECU. I drove a Pontiac Vibe (Matrix) a while back and it seemed to do the same thing, I dunno if it has the same drive by wire system.

Wow, you took the words right out of my mouth. This is exactly what's happening.
I have disconnected the negative battery already, and it seems to work for most of the time. Probably just my driving habits.
Also I remember when I bought the car new, it never did this until maybe 10k miles in? I hope this is normal for the car and abnormal for the driver.
When I press on the gas, the clutch speed is faster than the wheel speed. I believe the clutch speed is faster than the tires, this when i gas from a stop, it takes a moment for the car to move and jolts when it does.
Is the solution the same as above by disconnecting the negative?

One of his earlier posts states his car is automatic. It's really hard to get a handle on what't going on: if the transmission or torque converter is slipping or if the engine is not responding right away. I guess if the RPMs are coming up right away and the car isn't moving, it is a transmission issue, might be just low on oil.
If the RPMs aren't coming up when he hits the gas it's related to the what is decribed in the previous posts by CorCamrySE and others.
Not sure what causes this but I think I had the same thing happening to me before i seafoamed my car. Whenever I would apply pressure to the accelerator with the car at idle, it would have a jerky start as if the engine wasn't responding right away.

I see that in a seperate reply he states it's an auto.
That being said, his clutch can't be slipping. He also wouldn't have a clutch to begin with as he states that he does. Engine RPM's are always greater than wheel speed. The OP is trying to act like he knows things that he doesn't which is only making the problem harder to understand.
If there was any slipping, the MIL would come on with a code for a input/output speed variation (slipping) which isn't the case.
I'm wondering if the OP disconnected the battery as I suggested, or if he's just done it in the past. His posts aren't very decisive at all.
Well, I've learned what an MIL is and another reason for it to illuminate, so this isn't a complete waste of time, but what is 'OP"? I'm thinking Ron Howard from Mayberry....
