Just throwing out an idea that came to me while reading this again. Think it might be a clogged exhaust system? It would explain some of the symptoms your haveing.

I think it'* time to rule out the SC, too. Have you checked for boost? Are you getting what would be 'normal' boost now?

Boost level is fine. Listen I had a scan done today and nothin would come up on the snap on tool. The mechanic drove the car to his buddy who put it on "scope" and the result was like a x80 but it was told to me I need to replace the crankshaft sensor, so I bought the part from Autozone. I then took the front wheel off but it looked a lil difficult so I askd the Pep boys tech and he advised me I need to make sure I mark the original placement in order to make sure alignment correct on reinstall. Fell free to add what you may know abt this.

Steve, My buddy and I were outside trying to get this done b4 we gave up for the night and decided to go to bonnevilleclub. This post is very helpful. The biggest problem we were having is we were tryin to get off the plastic sensor cover w/o remvng the pulley bec the manual states not to remove the pulley but to remove the "damper". Steve, what is a damper and where is this balancer. So this pulley does come off then right??
Also I m going to have to buy a puller tomorrow, what do you recommend. One last thing the manual talks abt a "Woodruff key", what is that and do I have to mess with it?

you have to take the balancer/pully off to replace it. there are 3 holes in the front of the balancer. you have to use 3 long 1/4" fine thread bolts and a puller plate to remove it. also, pleeeeeeease make sure that the new crank sensor is indexed correctly, if not, the first time to turn the motor over, you will take it out.
also when you have the balancer off, check the rubber in the middle of it, i just replaced my balancer because it broke out

Just to repeat what I posted on the other topic:

Hello,

A "damper" is the same as a "balancer". It'* the large piece that is on the end of the crankshaft. It is actually two metal rings with rubber in between, one of it'* functions is to damp out vibrations of the crankshaft. Also, on this car the pulleys are part of the balancer, it all comes off together.

I'm very concerned because you are over your head with this job. If you have never removed a balancer from an engine, I don't advise practicing on your bonnie. Removing the bolt, pulling the balancer and putting it back together is definitely not for a beginner.

If you go to a good parts store, they should have a puller by a company called lisle, or possibly others. You would want to make sure they list your exact application, because it is a lot different from other balancers.

The woodruff key is what keeps the balancer locked to the crankshaft.

Again, I do not advise you attempt this in light of the questions you are asking.

Thanks,
Steve

A woodruff key does the same job as a standard key like the pulley on a 92/95 Supercharger, but it'* a bit different shape. It'* shaped like a 1/3 moon so to speak, with the curved part going into the crank shaft slot. When it falls out, you'll know what it is.

Steve, I appreciate your concern but I'm goin for it. Last night I had to run to home depot to get that 15/16 socket and I used a 1/2 drive breaker while my buddy held the opposite gear in place. Bolt is out. Also I bought the puller but I had to get different bolts for it bec the bolts supplied were all over 1/4". I had initially got some 1/4' x 6" bolts but of coarse they were too long. I now have purched 1/4 x 3" ajnd some 2" just in case. Im going to go do it now. I want this done 2night....
