If you have a painted, fiberglass targa top and it is properly adjusted it makes the car much quieter. During the summer I put my see through top on and there seemed to be squeeks and rattles everywhere.

If I remember correctly the fuel pump relay is under the dash on the glove box side. But I don't think that is the problem. Do you have access to a scanner that will give you real time info? The tach dropping to 0 makes it sound like an ignition issue. The turning and cutting out sounds like...

You should start by telling us what year and model Vette you are working on.

I ended up replacing them both. It still idles about 1000 when cold and 750 when warmed up. Not the right numbers according to the FSM. I even re-set the min idle screw according to factory specs. It is way better than 1500 when cold and 900 when warmed up. I think it has to do with my...

Possibly a voltage surge. Check both battery terminals and the positive connection on the alternator. Make sure they are all tight and not corroded.

There is a place in Warren Michigan called 'Bearing Service' that has almost any bearing ever made.

Could be a bad neutral switch.

Do you have any aftermarket ad on electrical equipment?

Look up www.c4corvettes.com there is an article on c4 performance mods. My initial thoughts are that your car may not be running properly and to make sure it is before doing any mods. My 92 was pathetic until I went throught the normal maintenance and tune up procedures to make it run right...

52 mm throttle body, aftermarket free flowing exhaust, check fuel pressure, plugs, wires, and make sure she is running correctly. My biggest gain came from new Bosch injectors, the old ones were SHOT. If you are looking for 400 hp it requires porting the heads, Headers and a cam.

Try entering the car from the passenger side. If it starts you have a problem with the wireing in the drivers door. Possibly the connection at the key lock.

I think the LCD is liquid crystal display; speedo.

:thumbNew injectors, IAC, EGR, TPS, plugs, wires, MAP and a 52mm throttle body. Now today a left oxygen sensor. BINGO! it finally idles down. So I spent a little money trying to figure this out. And I was looking for any excuse to get the 52mm throttle body. It was still much cheaper than...

Using the scan tool I can see the IAC counts changing as it idles down. When I stop it is idleing around 1200 and the IAC steps down till the idle is around 650. But it will not do this till I am completely stopped. At that point the count is about 14 if I remember correctly. It is a new IAC in...

Found the last ground terminal on the back of the motor today and cleaned it. It still refuses to idle down until I come to a complete stop. Hooked up the scan tool for the drive home. Left oxygen sensor jumps all over the place, from 120's to over 800. Very erratically. Bad sensor? Right...

Google "WCFB carburator" and you will see a site called "carb doctor". He has a free download on your carb. If no gas is getting into the float bowls then it has to be either a plugged strainer stuck needle valves or improperly set floats.

How old are the spark plugs? That would be my first place to look for trouble.

Today I used a greenie pot scrubber and rubbed where the butterfly contacts the bore just to make sure it isn't binding. Then I lubed it with wd-40. After that I added a second spring to the throttle. It closes completely now but still idles high. Hooked up the scan tool, idle is 750. IAC...

Google; Corvette St. Louis, MO. There is a ton of info...

It is a newly rebuilt throttle body.
