Gas Pedal Delay

wstar

The only time I've felt anything similar is issues with UpRev's revlimiter when I switch back from a low mph/rev -limited map to an unlimited one. If I switch and quickly take off, or switch on the fly while already rolling out through a parking lot, there can be delay before it opens up the limits.

I've felt lots of minor bog issues in this car related to various intake issues, VDC, and the inherent throttle opening delay on this car (which isn't a fixed timer, it's more like the throttle won't open fully until the revs get higher at current throttle settings).

My point about the v6 comparisons is that if the problem is any of these various minor issues with intake parameters, heat soak from high external temps, stock throttle limiting at low revs, etc.... those effects are not normally anywhere near strong enough to describe the problems some people describe in this thread (the multi-second delays with no throttle response at all). Even taking all of those factors into account, there should way more than enough acceleration in this car to avoid serious issues.

Whatever you're facing, it's not the stock throttle map's failure to open fully, it's not just the engine's timing when breathing hot intake air and/or having high coolant temp, it's not a minor intake volume adjustment, and it's not the normal way that the engine limits torque. The only thing that comes close to those symptoms in my experience is VDC limiting wheelslip when you floor the gas more than traction allows for while turning out onto a road.

Other than that, I think anyone that's having such a severe problem has to have a malfunction that needs to be diagnosed. Most of our cars *don't* have this problem, or there would already be a massive recall underway. Even everyday drivers who know nothing about cars wouldn't accept a high rate of cars just completely ignoring gas pedal input for several seconds inexplicably. They'd all be back at the dealership in mass numbers and this would be a huge issue.

If you can reproduce the issue reliably, but you can't figure out what it is on your car that's failing unlike most of the other cars out there on the road, then go reproduce it for a qualified technician (dealership or otherwise) and have them diagnose it. There's got to be something broken and fixable. Either that or a commonality between everyone who really has this severe issue that points at a common defect (e.g. they're all 2009 cars from a certain VIN range which have a certain option).
