+1.

Back on topic, this definitely sounds like dbw caca. One of the reasons I went with an AP1.

Well, the torque explaination doesn't make sense because like I was saying, when you first start the car, there isn't a delay in acceleration.
Its only when the car has been running for a while that I notice delay.
I mean the acceleration is not smooth as all.
You get it going in 1st gear and when you jam on the gas, it stutter for a bit before it start accelerating.

Except that the guys with the AP1 and '05 AP2 in the previous page both said they experience the same thing.

definately a few non driver factors imo. I notice that when Im going slow and I start off in 2nd sometimes the car feels slower for the first few thousands rpms (say 2-4k part throttle) than say if i went to 1st then 2nd and into the same rpms. It feels like the throttle maps or something get confused.

Interesting, I have an AP2 08 with DBW and there is never any hesitation. I have driven my friends 02 AP1 and there is a noticeable difference in response and power in favor of my car. My friend freely admits it. The gearing change, higher torque peak at lower RPM, downward shift of the HP peak, DBW throttle, and more powerful ECU all contribute to a better experience on the 08. I think the guys who can't afford a late model AP2 are trying to justify their used car purchase of older AP1's by criticizing improvements they have never even experienced. Whatever you need to drive away the insecurity.

If both cars are well maintained and operating correctly, you shouldn't be seeing a problem with either. With older cars, I'd be looking at vacuum lines, MAF, injectors, fuel pump, spark plugs, filters, etc. Basically the fuel/air delivery system followed by timing and ignition. Start with the simplest things and work your way up. Emissions controls and sensors are another place to look in an older car.
