acceleration annoyance

[schierholz]

So I got it to go away for a while now it's back
*92 5-speed*
A6

My car idles like a champ... and I can drive it with a Slow acceleration. But when I need power and I get heavier on the gas *to match the people around me in traffic, I get this slam of a jerk and for a split second watch my rpm drop to 200 and back up. If I try to slowly gain speed it won't happen but it's very annoying.

I was told to
Try a new distributior - new one in
Try a different coil pack- I have tried like three different ones
Get electrical grease and coat the plugs - done
I know the EGR can help kill the car so I changed that as well
And I do have the amazing bouncing tac from hell even though the cluster is replaced as well

It will not throw a check engine light and will Rev all day with out showing any signs
And I can *97% * of the time hold a constant speed without a very slight jerk.

Car runs great otherwise

Worn engine mounts??

Grab another ignitor just in case.
TPS maybe?

[Raf99]

Yep. I'd try unplugging the TPS and see what happens.

I second TPS..its a potentiometer..its old.. you know how old stereos have that crunch sometimes adjusting the volume.. same difference. If you have a multimeter hook it up and rotate it, it should be a smooth linear increase in voltage, if you get big jumps/spikes there you go..
closed ~.5 volts - WOT ~4.5v

Ive read though that the voltage type test can be inconclusive, so as a supplementary test set the meter to ohms and check for a smooth sweep with no jumps in resistance

If it isn't the TPS the car is running lean.

Weak ignition system leads to misfire under loads.

Try new spark plugs and ignition wires.

Does new distributor has new cap and rotor, too?

The bouncing tach is a sure sigh of a failing ignitor, I know it was mentioned so dont ignore it.
