1. Rattling sound. It isn't all the time. And when it does happen, it's only under load (if that makes sense to you guys). It's been happening for the longest time, and I really want to fix it. It's really loud inside of the car on the passenger side when driving. I don't know how loud it is outside the car when driving, obviously. I've been told it could be a cracked flywheel. I don't know. WHat do you think?


without being there in person, you will onlyu receive guesses from forum posters. You need to investigate and be sure it's not pinging from running 87 octane

2. I gutted my catalytic converter and it did cause me to lose some power.

HOGWASH


I plan on fixing it by putting a pipe through the cat.

fix what, the power that you DIDN'T lose?

As of right now, when the engine is running, you can hear a significant exhaust sound coming from the engine bay. It sounds like what the exhaust would sound like out the tail pipes. (a low rumble) What causes it to go through the engine bay? If I get down next to the cat under the car, you can't hear it. Any ideas at all?


bad header gasket (you aren't still running crappy exh manifolds are you) rusted y pipe, clamps need to be tightened. Again, you need to find it

3. There is a sound coming from my pullies. It seems to be coming from my alternator, but it was just rebuilt. My uncle used his mechanics stethiscope (screwdriver) and he saidmost of the sounds is through the alternator. He also said it could just be traveling from other areas. He then told me the bearings in my tensioner pully could be going causing that sound. Any help on that?


could be

A/C compressor
smog pump if you still have one
alternator
water pump
tensioner
power steering pump


are you seeing a pattern about how one needs to be there in person for certain problems

4.THE DOORS! I want to replace atleast the lower hing pins on my doors. Can I just buyt the pins in the help! section at autozone? I know they have the rollers on them for those door things(I don't know what they are called), but everywhere i've seen the kits don't come with those. Do I just reuse them? At autozone they have two different sizes for gm doors. Which do I use?

Sorry for the long post, I just want to get this car back into shape before getting too far into the body.

EDIT: Also, My emergency brake handle. DId they changfe the style of handle for 92? I've looked at pictures and mine doesnt look the same as others on here. Mine has a half circle thing on the side of it which the cable sits in when you pull the handle. It doesnt work as well as it used to and soemtimes hte cable pops out.

yes it can run on 87 octane. If you advance the timing at all then you need to bump it but, why do people on this forum ask about performance and then run 87 and let the computer retard the timing which reduces performance???? Also, did you know that if the timing retards a bunch that the engine actually works harder and emits more heat? Is heat a good or a bad thing? anyway, enough of that

2.Okay, I may now have lost any power, but I know it changed something. Not only me, but other people on this forum has had the same effect. All I want to know if it putting a pipe through the cat will fix it. I know somebody on here can tell me from experience.


ahhhhhhh, you've been reading posts from the misinformed about how removing backpressure hurts performance. Now i understand where you got the false information because those claims are false

3.For this one, all I really need is someone to say something along the lines of "they tend to get noisey after a while" or I've have the same problem and this fixed it." Anything that would elad me in the right direction.

again, a noise could be anything. lemme see, on my daughters Accord it was the A/C compressor. On my wifes Mazda it was the P/S pump. On my sons 4th gen it was the alternator. On my stang it was the belt, on my other daughters nissan it was the tension pulley, on my 3rd gen it was the smog pump

4. I was going to post about this somewhere else, but maybe somebody has a how-to to replace the door pins?

I'm not trying to boost my performance on 87 ethanol, as I cannot afford the higher octane, and I just want it back to what it was. That's all I ask.

I do understand the noise problem. Any way I can single out a pulley? I know I could take the belt off and spin each of them, but I doubt I could spin them fast enough by hand to tell if they make a noise.
