Default 95 bonne se - no power, stutters and shakes.

Hello everyone,

Yesterday my Bonneville started acting like garbage. It began to feel like it was resisting acceleration, and when it resists, it shakes. At red lights it almost feels like it repeatedly wants to stall out, but it never does. When I try to accelerate from a stop, it chugs and resists, but when it gets enough pedal, it will act better.

On the highway it was the same thing more or less. No power at low rpm, then I did ok as long as I was increasing speed at a good rate. If I let it balance out, it would start to shake/vibrate.

My 95 Olds is having this same problem, and so I re-plated my pain in the butt Bonneville, since it was running well at that time (RARE!). I checked all that I would check in my bonne in the olds a few months back, and everything I assumed would have been the issue didn't seem to be. Coils, TPS, cleaned maf, etc etc)

I got home late last night, and it was about -30 outside, so needless to say I didn't feel like digging into this problem. I'm at work now, and plan do use smoke breaks to go do basic trouble shooting (check coils etc), but if anyone thinks they have a pro tip for me, I am all ears!

No I have not. I picked up a tool to do that, but I have not had the time to try it out yet. Its on my list of things to do, but its nothing I can try here.
I only have basic tools at my disposal, small socket set, screw drivers, pliers, multimeter etc.
I hope to get home in time to try some other things.

Thx for the comment man

Thanks again Sawgunner

Well I bounced outside for a smoke with some tools and a multi meter, and decided the 1st order of business was to hook my amp back up. I recently had a flat, and to get to the spare, the power wire had to come off my main amp. I set the wire into a plastic lid from a spray can that was in my trunk, and left it there since last week.
I assumed it was tucked away from harm, and it caused no problems for over a week.
I hooked it back up, started the car, and its running like a damn top again. It must have been making a connection to the body of the car through the plastic lid.

I love it when my stupidity is immortalized on the internet! On the bright side, now its a double bonus for me. Car works, and I got my sub back!

(Shame) :( lol

Well its not all for nothing, I still have that other car with largely the same symptoms. The only problem is there is no amps in it. Might have to try a little harder with that one. I think I will begin with looking for electrical faults though, as the problems are nearly exactly the same.
I want my olds running cause its a nice car. has everything i can think of except heated seats and sun roof.
The bonne is still wayyy nicer though >: D!
Now i wanna fake sick, and drive my car and bump some music.

Thanks for the advice Saw, I will put it to use on the other car.
Have a great day

Not stupid at all, that happens to all of us!

Not likely that the voltage bridged the plastic cap though, you migh give that wire a voltage drop test. How large is that supply line. No Fuse? If so replace with smaller one see if it blows!

The Olds:
Do you have rear window defrost? that is a proble child area! Does the Olds have any electrical bad history?

Its a fat wire, although I forget the gauge. Its about the size of my pinkie finger, and it has its own in line fuse built into it. I didn't think it would breach that cap which is why I put it in there, but it seems like it did. 2 days straight my car was running like trash, hook up the amp, now its fine again.

The Olds was given to me by my grandparents. 1st/only owners other than myself. It has been well maintained to the best of my knowledge, but it may well have.
It does have rear defrost, but all seemed well with it. We had a lot of rain here, which caused some massive puddles. I rolled slowly through a few of them on my way home (probably deep enough to touch the bottom of the car)(it never stalled or anything bad). The car ran well for a day or two after this, but then started doing just what my Bonne was doing. It idles like crap. When you put it in gear with a foot on the brake, it really struggles. You can power through it at high RPMs, but anything maintaining speeds at low to mid rpms, and it will struggle pretty bad.
Before all this happened, the olds put my bonne to shame performance wise.
I checked the TPS, Coils, Cleaned MAF, cleaned TPS, new plugs and wires, and put in the narrow stove pipe where it usually makes the UIM leak.
I need to get it into the garage and put an amp into it pronto Ha-Ha.
