your right...i put monroe on the rear......and they do feel a bit firm.... yet its alot better, no more of the whole rear bouncing and feeling like my tires are going to be pulled off the back from bouncing so hard left and right when i hit a bump....thats gone atleast

True. I'm going to be ...

I put Monroe "Maxx" air struts on my mother's car when the originals started leaking oil this past summer. They are WAY too firm, IMO. I couldn't seem to find any other struts at the time..

If you would like to match the front and rears, the Monroe Sensatraks could be a good choice. The apparent difference between front and rear could just be the worn out struts. The Sensatraks will firm up the ride some.

You could upgrade the suspension, but you'd probably want to do it all around ...

Hello again. My mother's 03 Lesabre is in serious need of new front struts. It is a custom with the base "grandma" suspension. I replaced the factory rear air struts with Monroe "airmax"(?) last fall because all the oil leaked out of them. They ride on the firm side compared to the old ones so I was ...

I get the same noise like a bearing going bad (a whine) but mine only occurs when driving the car at around 50 MPH and it only occurs when you are pressing on the gas pedal. Once the noise starts, if you lift up on the gas, the noise goes away. There is no noise if you rev the engine when it is in ...

The nearest I can tell is that your car has a redesigned injector of some unknown manufacturer.

They are listed as 00-05 on that page. Pintle caps are typically not necessary for proper injector operation, but I can't speak for that ...

OK, it's all done. Running well and no leaks so far. Thanks once again for everyone's help. :hail:

The first time I drove it, the engine was "racing" but it seems to have resolved itself. It was also experiencing extended crank times the first few times I started it but that also seems to have ...

There are a few other problems, usually with the EGR or pulling up a QDM code. Or of course, the crappy Teves ABS, but that's not really a reliability issue...that's just a PITA.

QDM? Is that the quad driver code? I used to get that in my 89 every once in awhile. Never was able to figure out why ...

LN3's FTW!!

I found the wife's old L27 equipped 93 Lesabre was the best running overall but seemed to be "leaky". My friend had a 94 that also was a good runner.

Her old 99 Lesabre was just junk. I could never get it to run right, it always seemed to be having problems, and the power delivery ...

Sounds good. Besides this minor hangup (and a snapped IAC screw!), the whole job went very smoothly. A lot easier to work on than my 95 Grand Marquis. :puke:

I just have to get the injectors, TB, and other random stuff back on and plugged in. I just hope there aren't any coolant leaks at those ...

I don't really have anything to accurately measure those with. What should I use? The "nozzle end" o-rings are indeed smaller than the top ones. They are much thinner. I tried to push an injector into the bore with the "fat" o-ring installed and there was no way it was going in. It didn't even fit ...

How nice, the injector o-rings that came with the kit don't work with these injectors. They are a direct replacement for the top o-rings but are too thick for the nozzle ends.

Also, it came with these "sleeves" that don't appear to be used on this setup.

Ok, thanks. Picked a pack up today.

Found something odd. The #5 injector has a conical shaped tip on the nozzle end. The rest do not. What's the deal with that?? 8-[

Thanks!

Pics?

Alright, I ripped everything off today. What a mess. I'm glad I talked my parents into doing this before something bad happened. The writeup posted on here was a nice reference. Kudos to those involved in composing that:

Gunk in coolant passages. I think these are dead-end passages but still nasty ...

I just ended up ordering from the online vendor. Didn't feel like dealing with the dealer.

I'd like to flush all the old Dexcrap out of the system BEFORE I begin the intake job. Is there a radiator drain plug somewhere under there? I looked briefly under the car and all I saw was a giant plastic ...

Jeez, $12.48 to ship a couple of gaskets?? Is it still cheaper than going to a dealer?

Hello. The car in question is an 03 Lesabre, not a Bonneville. Hope this is OK.

I've searched extensively before joining. I think I'm going to go with the APN UIM and the revised aluminum GM LIM gaskets. I've done this job on both my old 89 and 93 Lesabres so it shouldn't be too hard.

My question ...

Greetings everyone. I recently began searching for info on the dreaded UIM failures and LIM gasket failures and stumbled upon this site. I'm a Buick man going way back. "mrbear3800" goes way back and I still use it for other forums as a tribute to my old cars. My first was an 89 2 door Lesabre ...
