Hello all,

My name is john i live in glen burnie md, my car is a 1995 bonneville ssei. VERY new to gm cars (most of my cars were foriegn) car is a little sick right now and no one i know has a clue how to help me get it running properly so i'm trying to learn something here. besides of the tranny, heads, OBD 2 and supercharger are there any other changes between supercharged l67 series 1 and series 2 engines? i believe i have a bad supercharger and thought about trying the series 2 supercharger.

Welcome!! If you can't find the answer to your problem by searching, please put up a new thread and hopefully we can get you a good solution.

Welcome!! Post your car's symptoms and the 92-99 guys will be able to help you out.

i put a basic tune up on the car changed the oil and supercharger oil, air filter and i'm still getting a surge or bump whenever the car starts making boost, car has 223k and supercharger makes a rattling sound.

Supercharger rattling is probably the coupler. That requires taking the S/C apart, which can be a little tricky. It may also be the cause of your surge. I'd replace that and see where it takes you.

thanks a lot will do

Welcome aboard!!!

There are a couple ways to diagnose where the rattling in the supercharger is coming from. If the pulley has rotational play in it, the coupler is bad. If you can wiggle the pulley at all up/down/left/right, the nosedrive bearings need replaced.

For the most part, supercharger rattling issues won't cause any drivability problems until the failing part completely dies and the supercharger stops spinning. Please post in 92-99 with a description of the surge you are getting. We've got great gearheads that may not see this being in the Intro section.
