TexasDan said:guys I just got me a barn find in a 82. been in storage since 2010. I can get it to run but its real ruff. fuel pump, filters were changed, new plugs, wires etc... I can drive it down the road and it will just die. I can start it back up but I have to WOT to get it started.
Are there any good shops in Northwest Houston Texas I can take it too?
as usual your going to be well ahead doing some testing and having the correct FACTORY SHOP MANUAL, to refer to, and start by verifying the basics, of spark, compression,fuel pressure and volume plus, your obviously going to need to verify fuel delivery, ignition advance curve ,timing and throttle body adjustments , proper valve adjustment and proper sensor function, and without a shop manual to look up the values your supposed to be setting things for or values you need to verify and a few tools like a multi meter and vacuum gauge and timing light that will be far more difficult.
check all the fuses both in the pass side dash fuse box and under the hood near the battery , clean the battery connections, replace the fuel filter, and replace the oil pressure sensor near the distributor base as these frequently fail.
An hour spent reading links and sub links NOW can save you days of frustrating guess work

that twin tb systems not that difficult to work on, the first thing ID do if it was my car would be to, verify the fuel pressure at the TB inlets correct and set the ignition timing, and verify the voltage from the alternator, and battery.then I'd take off the TB's one at a time and use a full can of throttle body cleaner on each after partial dis-assembly to get them clean, next suggestion would be to add a can of injector cleaner to the fuel tank. then check all the fuses, look for loose electrical connections and vacuum lines and Id strongly suggest adjusting the valves and an oil and oil filter change, ID strongly suggest checking all the fuses, and looking for vacuum leaks. and ID replace the oil pressure switch as they have a well known track record for being intermittently defective, which can make you nuts tracking that issue down,ID also suggest replacing the distributor cap and rotor as older,components, with wear and internal deposits tend to cause ignition issues, and get out a multi meter and replace any ignition wire that reads over about 2000 ohms per foot. and ON BOTH THROTTLE BODYS, ID verify the TPS is set correctly, and ID clean and verify the IAC is also and if not replace it.
ID also verify exhaust back-pressure as an older partially clogged catalytic converter is a common issue , on those corvettes.
yes there are throttle body rebuilders and parts
you can easily fabricate a low cost yet very accurate,custom built MANOMETER
(fancy word for a tool that allows you to balance and equalize the flow rates of the two throttle bodys on the cross fire intake manifold
and just as important, LEARN HOW TO CORRECTLY USE IT!
It took me awhile but I learned you need to put a couple cap fulls of the dark blue MARINE STA-BIL in the car generator or any other engine in storage, gas tank , or several ounces in a cars gas tank,before you store it, or in several weeks time the alcohol makes the engine hard or impossible to start.
be very sure,
as a general rule with any new automotive toy,
(1) you check the oil, trans fluid or coolant and brake fluid levels
,(2) the tire pressure is correct in all 4 tires,
(3) verify the fan belts are in decent shape,
(4) verify that you have the ownership documentation, the required licences
and you test the brake function, before driving.
(5) start it up and let it idle for 10 minutes and check the oil pressure
and coolant temps.
(6) try shifting it into all gears.
(7) check the signal blinkers and head lights
