unsure, I would be able to tell a lot better visually. That's why I recommend you take it to a shop just for an inspection and go from there.

The IAC (Idle Air Control) solenoid is sticking at times, sometimes simply removing it and hitting it with carb spray helps it work better. But usually replacement is the only long term fix. Could also have a vacuum leak, but that usually doesn't cause such a high idle. To verify its the IAC, when it acts up lightly hit the solenoid with a hammer. This allows the pintle to move back to the correct postion and restore the correct idle speed.

It just shoots up to 4,000 RPMs immediatly when you go into neutral?

i agree, however if its doing that alreadyreving high like that the internal spring is shot. i dont think hitting it will do anything. or else a TPS sensor....

yea, there was a lot of slack in the throttle cable so i fixed that but it wasnt the problem.

my sister doesnt have the owners manual so i cant find the idle control. and i dont think its sticking because i can be at 1500 rpms and it will still rev up.

Trust me working at dealership I've smacked alot of IACs in various vehicles and it does work 75% of the time. Its not the spring but the rod that the pintle is on that causes the problem, thats why hitting it dislodges the rod and returns the idle to normal. If the TP sensor was faulty a code would probably be set and acceleration could also be affected. But by the same token the IAC sticking could set a engine overspeed at idle code, but that usually only happens with auto trans cars.
