Not sure if both of the problems are related, but I literally took the car out the other day and she was running more smooth than ever before. Came back and parked her at the shop, was going to take her for a little spin tonight and warmed her up, hopped in with my lady and right when we are going to take off I let off the clutch while going to gas and the petal nearly gets stuck (while applying normal pressure) and didn't really want to budge. Car also is acting like it was when one of the injectors was clogged and when going near boost starts loosing power. So, I turned it off and went to the store to get the drink we wanted and come back and hop in and toy with the petal while it's not running and it's making a weird, almost grinding, creaking noise when you press down on the petal. I went out to my throttlebody and gasses it there and it wasn't having any issue when I manually gasses it from the throttlebody. Anyone have a idea of what it could be?

It's binding some place cable or linkage got to look under to check where noise is coming from listen and visual


Good luck

I've been looking. I think it's just old... Was going to unlink it from the TB and spray WD-40 down it and let it work its way down the line some and see if that helps. I worked the petal out some with my hand while it wasn't running and just took it on a drive and blasted down the gears and dropped the gas to the floor and it deff wasn't having the same issue as last night. It's still a little rough but I'm starting to think it may just be from old age... weird though because I had driven it with no issue then started it up the other day and the petal felt still (almost thought it was because my powersteering was low for some reason) made sure to fill that up and restarted it and got the power steering through the lines and went to gas out of there when it warmed up and the car barely rocked when i let the clutch out haha.

Check your negative ground cable, if itís not making good contact to the block then the throttle cable gets used to the demise of the cable.

Like Scott said.
Like arc welding the throttle cable because of a bad engine block negative ground.

Clean it up. Or it will happen again.

Do you still have CC?  The CC cable also attaches the throttle and could be getting bound up for some reason.

Well, I've just gone ahead and decided I'm going to get a new throttle cable. Does anyone have the part # for our cables? Or know where to get one new.

Okay, got a new throttle cable and installed it,  now when my gas petal got tough it bent the petal some so I bent it back up, but when I let off the gas now sometimes it gets slightly stuck on open throttle. I was pretty sure I adjusted the cable good, I'm going to recheck it today does anyone have any other idea?

Do you still have the extra return spring on your throttle body?  There is one spring that is coiled up on the throttle shaft and one more that's on the outside so there should be two Springs returning the throttle plate to its position.

So actually, I ran this thing maybe once or twice since I replaced this and had to park it so I could get it road legal. I go to take it for a test spin today to make sure everything is fine because I have a kid on the way and this is the car it is suppose to come home in.

My farging throttle cable is stuck again, what the actual f*** could be the issue here? I fixed the major ground and just wasted $30 on this damn throttle cable for this same problem... Not sure what else it could even be but I need to be able to gas the car.

You have to go step by step and move and feel every place and look for something that's binding. Usually there is evidence somwhere of something binding. If l was you l would get a buddy to help out moving things while you observe every movement and see what you come up with. Good luck

Allrighty, I got her figured out everyone after a angry night and hunting it down today. Checked all my grounds and we were golden, what it ended up being was. I took my turbo heatshield off when I rebuilt my motor, I saw several others running no heatshield. Not sure if I'm just unlucky, or if people heatwrapped their throttle cable, but there is a rubber/ plastic coating inside of the throttle cable that it slides through and my turbo heated it up too much and stuck it to my cable. I ended up having to tear my cable apart to figure out what was happening because I didn't want to be oblivious again, but if anyone has a spare throttle cable I'm looking. Send pics to my pms and a price. Please and thanks.

The factory cable did have some sort of heat wrap with a foil like outer layer.
It was where the cable circled by the header spark plug area.

Yeah. My original one had it and the second one that I bought was mostly gone, so it probably just took a while to eat through my original heatwrap and melted the plastic to the cable some, and then with the heatwrap basically trashed it just melted it after one start. I've already figured what I'm going to do is get another cable, heatwrap it fully in the bad stuff that they have. Maybe even put my heatshield back on, and see how that runs. Still need to throw a 180 thermostat in it and see if it brings my temp down too.
