Hello,


I have recently experienced a problem with my 96 Bonneville. When accerating onto high ways, the car will like jerk between 50 and 60mph, its hard to explain, but i can feel it like jerks/hesistates, and the harder you push on the gas, it does it more, then goes away. Now this doesnt happen all the time, sometimes it'* fine and accerates without any jerk to it. The RPM'* dont jump when this jerking occurs, so i hope it isnt the transmission, what else could be wrong? maybe the tranny fluid needs changing? any suggestions would be appreaciated...thanks...

You may be experiencing the same thing as me and I have not been able to fix it yet.

I have a 3.1 turbo and it'* doing the same thing. I changed the plugs. now I'm going to change the wires and coils.


hope someone figures this out.

I have the same problem here. The only thing I found that helps is 93 octane. But it is more expensive and I don't get as good as gas mileage. It also happens to me when I go up a slight incline.

Also in the last 8000 miles I have replaced everything I can think of.
Transmission Fluid and Filter
PVC Valve
Fuel Filter
Serpentine Belt (Gatorback)
Plug Wires (Bosch)
Spark Plugs (NGK Iridium IX)
Thermostat (180 degree)
Tires (so it shouldn't be a problem with balance)
O2 Sensor (AC Delco)
I keep my oil changed and ail filter cleaned regularly.

I am working on money for MSD wires and Coil to see if that helps. The only other thing that I have heard of is the fuel injectors and rail can cause some problems.

I have that problem, tuning it didnt seem to help. It olny seems to do it on inclines, definatly not on downhills. Will do it in all gears given there * a hill and low rpms. I do notice that it doesnt do it when the engine is cold.

Though these articles wont really help because nobody knwos the solution to this problem, check em out...

Yea I know. They were suppost to be the best ones Autozone carries in stock but once I got them on I noticed they were only 7mm(sucks). At they time they were a lot better they the stock ones because the insulation was completely gone on one of the stock wires. As I said in the previous post I am saving up the $'* to get MSD wires and Coils. The wires will come first.

The only other thing I know is that I have my MAF screen removed and still have my stock air box. I am going to try and finish my RAM AIR system tonight and put the MAF screen back in and will see what happens.

I have the same problem and have been following all the threads about it for tha past cule of months. I haven't hadtime to do anything about it yet, and it'* not really that bad, but it drives me nuts cause it just ain't right.

It feels to me like it could be a problem with the torque converter lockup...does that make sense?

I have had the same problem. I have put in new plugs and wires. And had a new tranny put in it, and it still does it. I took it to my auto mechanics class and put my car on the scanner and it said something about a crank sensor or a cam postion sensor. My teacher said that the cam senor could cause the car to do this when you are around 50 -60.

I got my ram air working (not finished but it working) and I replaced the MAF and it seems to be better, I don't feel the shutter anymore but I haven't drove it very much since then. I will get some pictures of the current ram air setup and get the posted soon. I has been raining for about 3 days here and no sign of it letting up.
