Is this normal?

[DPesso]

I was just wondering, I have an 04 TSX, I used to have an 02 Maxima and when I was cruising on the highway at speeds of 70+ if i let go of the gas, the car still coasts and doesnt decelerate until a couple seconds and if it does it decelerates slowly. I was cruising today on the highway going about 75 and I notice once I let go of the gas the car decelerates quite fast compared to my maxima. Is that how its supposed to be with this car or should it still coast? Can there be a problem? Thank you.

I get that too.. I presume it's normal.

Manual or Auto???

sounds like it might be a seized caliper... something is dragging slowing your car down more than normal... does it roll at idle?

It could just be the automatic transmission downshifting or the torque converter unlocking (or locking, not sure how that works) causing the speed loss. Its probably normal so that when you let off the gas, the car begins the slow-down process.

(I'm not positive about this, but it kinda makes sense to me. Please correct me if I am wrong....I don't want to give out bad info.)

that is call DRIVE BY WIRE... do to our throttle body are control by wire, well it takes a few seconds for it to recognize that you let go the gas..

He was referring as TSX decelerate FASTER than Maxima when he let go the gas, not the other way around.

It really depends on what speed, what gear you are cruising on. When you let go the gas, the throttle body butterfly does not close completely, instead there will be gap and resting @ the "Resting position" of the DBW TB, not "closing position" unless you also step on the brake completely.

The Maxima has a V6, which is 2 cyclinder more than our TSX I-4. Thus it will be able to cruise @ a higher speed @ a lower rpm compare than our I-4 (also depends on gear setting), even when both TB @ the same "resting position", the maxima will still able to run @ a higher speed, which is what you used to your regular cruising speed.

i have an auto, i doubt its a sticking caliper because when im going 20 or 40 the car coasts for a while, or wen im idling it coasts, if i had a sticking caliper it wudnt even idle good. correct? so is this normal you guys are saying?

Well, i've never driven a maxima but my TSX seems like it coasts pretty good... My last car was a 95 accord and I dont notice any significant difference in the way the TSX acts when i let off the gas... maybe its just what you're used to from driving the maxima.

*shrug* doubt anything is wrong with the car, at least I hope there isn't good luck

Comparing the TSX to a Maxima is apples and oranges. I suspect the difference has to do with vehicle momentum and different amounts of engine braking between the two cars at different rpms.

I also just came from a maxima, I think it could have something to do with the fact that the maxima (mine anyway, a 2003) is bigger and heavier so it gains more momentum and can therefore keep coasting longer?
