Was is pegged at 120 before? What brand sensor did you put in? As long as you're around 40 you're fine.

I see no problem. Sounds like normal oil pressure to me. If its getting down to 20psi at idle you would have a problem.

Oil pressure and compression are 2 very different things.

What was it doing before that you are now thinking you have a problem?

I know you replaced the plugs, but did you replace the wires? Based on everything you've mentioned, that's what I would look into.

I've installed dozens of the kits, and I've never scuffed the walls nor replaced the pistons. Just replace the springs and spacers and be done.

Are you noticing the misfire at idle or under load? Compression test to verify you don't have a chipped piston. Might be time to get a proper scan tool if you want to continue working on it yourself. Otherwise you'll just keep launching the parts cannon. Even the "Torque Pro" app will have...

Water leaks are very common, usually from the interior door water shields. The carpet can be dried out, but it will take days, even in the sun. It is a huge sponge. The gauge of wire you used shouldn't matter, its just a communication wire. Are you sure you have all 4 wires going into the same splic...

Then install the thermostat and housing and continue to fill...

You will need a special tool for the fuel line disconnect: https://www.amazon.com/dp/B093ZTFGRK

If you're unsure, take pictures of every step along the way. Label all your bolts/fasteners.

The only symptom of a leaking valve cover gasket would be smelling oil as burns on the exhaust manifold. It is NOT causing your issues with brakes or AC, 100%. It is not a difficult job and its really not that different being supercharged. You DO have to remove everything in your way. All the bracke...

Cheapest performance mod ever! Drive at 40% WOT until you get used to it...and then put the bolt back in :twisted:

I can drop one in the mail for you, just PM or email me your address.

It doesn't look like you're making it to the stop on the linkage. It's hard to tell in your video what is holding it back. Have you taken off the intake ducting to physically look at the throttle plate?

Here is a video I made showing how much rotation there should be.

Likely two separate issues, do you have any codes? 1. Leaking fuel pressure regulator causing fuel to flood the vacuum lines basically flooding itself out. Check for any wetness in the vacuum line off the fuel pressure regulator. 2. Could be many things causing it to misfire and as soon as it sees a...

If there was recent work done, I'd physically check the throttle body and cable for issues. Can you open the TB all the way by hand? If it only shows 40% when you have it all the way open, replace the TPS.

You need to address the vacuum leak before any further diagnosing. It will probably take care of the issue as I can hear it whistling. Best way to fill the cooling system is to remove the thermostat housing & thermostat and fill coolant at the radiator until it comes up to the level of the therm...

Do you have spark? Are you sure the plug wires on correctly? Did you forgot the ground that bolts to the front head by the coolant elbows? No, a little vacuum leak wouldn't cause a no-start. https://www.gmforum.com/attachments/2000-2005-90/66887d1501344018-firing-order-yes-i-am-idiot-wires.jpg

Rotors look great, coating is still intact. Normal for them to be dirty like that. There are no rotational score marks. Clean off a little of the grim. If they are shiny metal, that means the coating is gone. If they are gray, the teflon coating is there.

I agree with replacing those plastic pulleys with some new metal ones to help with the noise deduction and also to make it more reliable. Those plastic pulleys are known to grenade when the bearings start to get warm. The supercharger will have some resistance to it, hard to convey how much over the...

The whining noise is definitely coming from something belt driven. To eliminate the SC, just take off the SC belt. If the noise goes away, spin all the pulleys by hand to see if any of them feel rough or wobbly. If the noise doesn't go away, move on to the serpentine belt, remove it and spin the pul...

I'm not close, but I have plenty of SSEi's. However, I'm curious...what is the point of this study on a 24 year old car? The peak of aftermarket, well that ship has sailed. Who wants this data and why?

Yes it sounds like you are on the right track. If you have an audible hissing sounds it should be pretty easy to use your ear to find it.
