This is paraphrased from what Custom88 had explained to me. Apparently, pre-90 all 3800'* used a rubber tensioner to keep the timing chain nice and tight. Over time, the rubber teeth would wear down causing unwanted slack in the timing chain. Post 1990 til now, GM modified their game plan and redesigned a larger metal tensioner, one that would not wear down after 100 000km. So, that being said, you don't have to worry, your tensioner is fine. In my case however, when the timing got fixed, the service guys noticed my pre-1990 3800 had a METAL tensioner already, so, they were confused. They typed in and ordered a rubber tensioner. Well part A from my car didn't match part B from GM. Bells went off....ding ding ding, was this a rebuilt engine? was it a swap?. My car was custom built order from GM, I have a lot of high end features for an SE so for some reason the factory installed a metal tensioner. To correct the inconsistancy, the dealer re-ordered me a new metal tensioner.

Put it this way, you've had the timing (code 41) thing dealt with...don't sweat it anymore...

Oh...enjoy the full meal deal
Wait... I wonder if that is why I get a code 41... I have 123.000 mi and that is when I got the code 41....do you think that I should get the timing chain checked out? I have an '88.

Code 41 is generated from a misread of the cam positioning sensor. If your cam magnet is broken, cracked or fallen away, your ECM is not reading the signal correctly from the CPS. Usually when they change and replace the cam magnet, they'll also change your timing chain and tensioner. If I were you I would ask for the metal tensioner that was stock installed on 90 and 91 Bonnevilles.

I would assume you have long term plans to keep your car. Fixing the cam magnet problem, being as expensive as it is....totally revitalizes your car

Ok today is not shaping up to be a good day

On my way to work today, my Bonnie stalled in a turn.
I tried several times to get her started again, but she'd stall out right away. That is, until I realized I had to keep my foot on the gas at all times.

So I drove to work, whenever I'd get stopped at a light, I'd put her in neutral, keep one foot slightly on the gas and the other on the brake.

When I got to work, I parked her and rev'd her upto 3500rpm, she'd drop to 1000rpm, then it would climb to 2000rpm, then down to 800rpm, then upto 1500rpm, then back down to 500rpm, at which point she'd stall out.

I'm debating trying to drive it over to my mechanic (5km away, thru heavy city traffic), or waiting until the end of the day and see how she is.

Does anyone have any idea what might be wrong

I suspect whatever is effecting my **** poor performance is doing this as well.

Those symptoms sound like a fuel delvery problem.

Hrm... sounds possible..... what about a throttle position sensor problem?
(I'd had problems with that in the past, but normally it only caused a rough idle)

Also, just a note, when the car idles normally, the steering wheel really vibrates, but if she'* anywhere between 2000rpm and 3000rpm or higher, no vibration in the steering wheel? Maybe related, or yet ANOTHER problem. Someone suggested engine mounts... but anyways, back to the main problem of not being able to drive it.

Ya, one step at a time, while the drivability issues are being addressed, just mention the vibrations. Does the TPS throw an error code?

The drive home was normal, she didn't stall once.
I checked the ECM when I got home... no codes.

I tried starting her 10 times, in the driveway, she stalled twice.
I let her sit for 5mins, and tried another 10 times, she was ok.

Any suggestions on what to do now?
