shop capable of performing a compression check?
I need to get a compression check done and I'm not familiar with any shops in the area who are able to do this.. Preferably as close as possible to Hampton... Could someone point me somewhere good?
Thanks!
Thanks!

Just a tip:
If you do decide to just get a tester and do it yourself (and you've never done it before) be sure to pull your ECU or Injector fuse before you start.

I am in Hampton and I have one. If you have a 4 cylinder car I can help you. I think Auto Zone rents them for free though (with a deposit that you get back after you return it).

Re: shop capable of performing a compression check?
I went out and bought one from Advance and will most likely be doing the test tomorrow...
replied to your PM profroop, wish I had checked back sooner...
The directions on the package are for a carborated engine, could anyone give anymore advice for an EFI engine?

- Take out yoru ECU or Injector fuse (cuz you don't want the engine to start and/or flood while you're doing this).
- Take out the first spark plug (doesn't matter which one to start) w/proper spark plug socket.
- Screw tester in where the spark plug used to be.
- Make sure tester reads no pressure.
- Jump in car and turn the key. Let the motor try to turn over about 5 or 6 times (and it should not start if you pulled the ECU or injector fuse).
- Go back to the tester and mark down the pressure reading on some paper along with some kind of label for that particular cylinder (EX. Cylinder 1-180psi).
- Release pressure from tester using the valve.
- Jump BACK in the car and turn the motor over again 5 or 6 times and check the tester again to make sure you got an accurate reading the first time.
- Release pressure from tester and remove from spark plug hole.
- Move to the next cylinder and start by removing the plug and screwing in the tester.
- Keep moving from cylinder to cylinder getting the pressure readings from each one.
- Compare the readings with a factory service manual to make sure they are within allowable specs.
EDIT: If you check the readings and they come up with numbers like, 20psi you'll know something's screwed up. If you get a low reading take out the tester and screw it back in again. Might have the tester in sideways or something.
