How to install a crankshaft position sensor on a 1992 Buick Park Ave, 3800 engine w/turbo. Without the J37089 tool that cost >$350. I can handle more complex, just can't handle more money than I have already spent.

You could try and eyeball it, I’ve gotten away with that a few times. It’ll mean leaving the stone guard off and installing the dampener to see if the vanes on the dampener don’t touch the sensor. When you think you have it centered then remove the dampener and install the sheild. It takes a little extra time, but that is all the J tool does for you is center the sensor, it’s not a timing issue.

DanD,
Thanks, that worked. Still having problem with idle speed at around 500 RPM, should be 800 RPM. Does not shutdown as before, though still low. Any ideas?

You could start with cleaning the throttle plates and IAC (Idle Air Control) motor. Sometimes carbon will jam up the IAC and it will not move when the PCM commands it to open or closed. You’ll have to remove the IAC to properly clean it, it’s held on with two screws. Don’t loose the rubber O ring that seals it to the throttle bore.
After you have cleaned the IAC try wiggling the pintle valve back in a little just to make sure it’s not jammed. It takes some effort on some of them to get the pintle to move.
If you’re going to clean the throttle plates you may have to remove the mass air flow sensor, if it’s the style that’s bolted to the throttle housing. Don’t no matter how tempting it is spray through the sensor, unless you want to buy a new one.
You can buy air intake cleaner in an aerosol can at most parts suppliers, spray everything down that you want to clean and let it sit for a minute or two then wipe down with a clean rag. I use a small bottlebrush for the throttle plate, makes it easier to get at the backside of the plate.
You’ll likely have a bit of trouble on the restart, most of these cleaners don’t like to burn.
Just play with the throttle and the engine usually will fire and clean themselves out.
There are a bunch of other things that will affect idle but cleaning these will be the place to start.

DanD,
Looks like I will be replacing the IAC Sensor. I took this out several days ago and found it was very dirty with deposits. I used a carb cleaner to clean it out. Looks much better now. I did not see any change in the idle after cleaning this part. This will be the next item I change.
Thanks,
P.S. Do you know anything about Mercedes Diesels?

Ya I sure do know something about diesels they stink and make way to much noise. LOL
I think my dislike of them stems from when I was a kid back on the farm having to listen to one all day out on the fields and then my dad thinking that diesel fuel was the best solvent in the world for cleaning parts.
So sorry I won’t be of any help with any diesels, the thought alone sends me into a flash back. LOL

DanD,
Thanks for all your help. You are right diesels are a big hassle. One thing I appreciate is their torque.
