Maf and Cps are notorious for being BAD even when brand new... usually go with a junkyard one, re-mans are horrible

its either the coils or the ICM... its pretty simple with the 3800 engine. Glad you figured it out My friend Bonnie had a coil blow...and he was broke..so i said just buy one coil..and replace and test. sure enough the middle coil was bad... now he is good. NEVER EVER BUY AFTERMARKET CHINA JUNK ...

as Bones would say " he's dead gym" band is gone... happened to me... had to buy a new rebuilt tranny... no way around it...sorry

Yeah I avoid any CHAIN repair place like the plague. The Free thingie was just to get u in the door to charge u some ridicolous price. but i can see how you went that route.

You know the 2003-06 bonnevilles all have defective guage stepper motors.

Well ebay has a kit now for like 25 bucks ...what included 6 new model stepper motors and soldering iron...solder... dash bulbs ..everything you need.

my gas and volt guages were dead... and i had about 4 blown bulbs

Thanks for all the help guys. Don't think the "all in one" package is in the budget.

Irony:
driving a car that's 15 years old because you can afford a new one.
As the car starts needing repairs, you don't want to spend the money on repairs because it's such and old car.
Yet you can't afford a ...

replaced both control arms...fix my problem with that....when those rubber bushings when they rot ..its shake city at highway speeds

Just for grins, I would like to know how you diagnose a bad control arm.

Was it bent, like in an accident? Was the rubber bushings falling out?
Was it rusted completely through (hard to fathom)?

It seems like it would be impossible for a home garage guy to jack it
up and put enough force on one ...

original factory arms 156K on em

i had a very similar problem..and the control arms bushings were bad... problem with that.. your cant get just the bushings from what i have seen.. its cheaper and easier to get both replaced... fixed mines... my mechanics says those bushing wear out and will cause that.

i know some people are dealing with this 50 MPH shaking thing.... mines was so bad it felt like the car was about to fall apart...

my problem? The Control arms. Replaced both brand new... shaking at 50 mph is over.

Mind you.. i replaced everything else and have new tires ( balanced) but nothing ...

I have the same problem. While at the mechanics yesterday getting new shocks put on ..he looked at my front end and said it looks like its the control arm bushings causing the 50 mph shaking. he said its much better to install new arms with the new bushings already in them.

IM either used factory or brand new delco..... aftermarket electronic parts will leave u broke down on the side of the road

i had the identical problem and it was low coolant.... charged it up and its like a meat locker in my car

I have that world re-known Bonneville highway shake. it does shake at all under 50... but at 50 it gets violent.

I had new tires installed and balanced
new tie rods and wheel hubs
Full front computer alighment done.

But i still cant go on the highway with the car... could my axle be bent or ...

outside wear only grinding down to the steel belt really quickly

What makes aftermarket ICMs so bad? Also, if the Delphi and ACDelco are the same ICM like most ACDelco and Delphi products, then I don't think the ICM is the issue. It was running a Delphi ICM until it started misfiring again. I picked up a brand that I can't recall the name of from O'Reillys (it ...

My buddy took his bonne for an alignment at Tires Plus and was told they cannot align it becaue something is bent?
