Question: Does this hesitation occur as a jerky surging feel though the whole acceleration?

Do you press down on the throttle ½ to ¾ and it feels very sluggish?

This is what is going on in my 93 LS 400 W/102,000 mi. .

My car has torque and smooth acceleration for about the fist 5 to 19 minutes that i drive in the morning. Then it goes down hill from there.

Amongst my armature diagnosing found that if I unhook the battery cable to reset everything and then go drive it immediately after it run smooth and without hesitation for about 5 to 10, then down hill again. I stop lift the hood and repeat the battery cable unhook. The thing runs good again for 5 to 10.


Question for all to ponder: Is it a bad sensor or sensors that are sending bad info to the computer? Is the computer adjusting for bad info causing hesitation and sluggishness? Does the cutting of the power to the computer reset it back to stock settings (fuel mix, transmission settings ect.)

I don’t know. But for all having this problem try the battery hook, re-hook and drive a couple of time and see if you get the same results. If so then what next??
