Late response after stepping gas pedal
Recently I had to step on the breaks a little harder than normal at a traffic stop. After the road was clear again, I stepped on my gas pedal and found my car revving but not going anywhere. It took about 1.5 seconds before it finally lurched forward.
My 90 v6 is responding normally again but I'd like to know what would cause this. Hoping to avoid having this happen again if possible.
Any thoughts?

I stumbled across this somewhere on this forum and gave it a try. It does indeed work as long as its truely not a transmission issue your having. I dont recall who posted this im glad they did.
in case anyone is interested:
"Try recalibrating your throttle, turn key on, but don't start engine, just wait till all the sys check lights go off, about 5 to 8 seconds, then slowly press gas pedal all the way to the floor, this means you should have it floored in about 1 to 2 seconds. then let up, take foot off gas pedal, turn key off. Now start your engine, go for alittle drive, your throttle lag should be pretty much gone. This works on stock or after market tunes. This is how the pcu calibrates the rotery transducer (electronic throttle). This is why in the Owners Manual (yes you should read it) it tells you not to push down on the gas pedal when starting your engine. The pcu will get a false signal input and miss calibrate your throttle."
