Throttle lag due to slowly comming out of lean burn on decel
From what I gather there are/ were two types of lag, I am talking about the one described below:
My car (gen 2, v6, auto), like many here, suffers from throttle lag. It is particularly bad after rapidly slowing down to around 15 mph or so and then giving it some gas, say when coming out of a tight turn. During the ''lag''' I see my revs increase but there is no corresponding acceleration and then all of the sudden, BAM, acceleration, as if our cars have a clutch that suddenly grabbed. I THINK I know why this happens. I believe our cars go lean, or even shut off the injectors during deceleration for mpg and emissions sake. Once we get back on the gas the car simply takes to long to get the fuel pressure and injectors going again. This would explain the revving with no corresponding acceleration and the sudden lurch of power once the cylinders have proper amounts fuel. If I could find a shop to modify the cars lean burn parameters on decel then maybe I could fix this problem. Also this would explain why Toyota has no fix. They don't want to affect the MPG or emissions numbers.
Anyone know of a shop in Southern California that can modify the lean burn/ injector shut off parameters?
