Just a tip when using shrink tube, as a protective cover,
over wires leaving an electrical socket or sensor,
Ive generally found adding some silicone sealant,
on the electrical connection to wire exit areas, to the area the shrink tube covers is a good idea to further reduce moisture damage

I can,t believe the number of times I use this insulation rubber shrink tube sections ,to make electrical splice repairs so it makes a great deal of sense to buy in the larger package sizes as you get 5-7 times as much tube for less than 3 of the smaller blister packs contain
buy a CHEVY SHOP MANUAL FOR YOUR YEAR CORVETTE!
set and verify your ignition timing, pull trouble codes,set your tps and iac,, then check for vacuum leaks on the lines and intake,then get out your multi meter and verify all the sensors, chances are good its a defective heat sensor or defective o2 sensor, a logical step by step approach will lead you to the problem, youll be amazed at what youll learn reading links. use of a shop manual and multi meter can be very helpful

your working at a huge dis-advantage if you don,t have a factory shop manual for your specific year car, and basic tools like a multi-meter, and vacuum /pressure gauge
http://www.harborfreight.com/fuel-injection-pump-tester-92699.html
THINK LOGICALLY ,ISOLATE AND TEST,NEVER ASSUME!
PULL THE TROUBLE CODES AND USE THE SHOP MANUAL AS A GUIDE,
YOU may be amazed at the number of times a bad sensor or loose wire, bad ground or blown fuse is the problems cause.
I've seen guys rush out and spend hundreds of dollars on parts,too fix a problem, take a great amount of effort to tear apart the dash or other area and once the new parts installed it still won't work, so forced to do further research at that point they only then find a blown fuse or corroded electrical connection.(that was the true initial cause)

yes they always seem to assume that everyone has unlimited access to both tools and every possible part and location on a corvette, youll need a good multi meter AND an assortment of test leads and it helps a great deal to have visited a salvage yard and grabbed a bunch of electrical connectors to use when making test lead connections, or they can be purchased as replacement parts
the search feature, is always an option here, on this site, but to save time , look at the sub links in these threads, to find sources for replacement electrical connectors, and NAPA can frequently ORDER replacement connectors for repairs at about 3- 5 times the cost youll find them at else ware, but at times getting the part the next day beats waiting a week so the price may be justified. if its a connector thats likely to break frequently buy extras, and have them handy

having a wide assortment of different multi meter test leads available is a huge benefit while testing
the clip test leads that test thru a wires insulation without much damage are a big help
NOW IF YOURE JUST LOOKING FOR A INTERMITTENT PROBLEM WITH YOUR CORVETTE THIS MAY HELP
theres several obvious and a couple less obvious things to check,start by pulling trouble codes, checking for loose electrical connections and vacuum lines.
Id start with checking the injector resistance and verify pulse with NOID LIGHTS , check the fuel rail pressure and ignition timing and advance, , ALL SHOULD BE OBVIOUS PLACES THAT COULD CAUSE PROBLEMS , loose electrical connections and grounds are always suspect, the most common cause I find for the lag,well (after verifying its not injector or fuel pressure or OXYGEN SENSOR RELATED or ignition , or knock sensor related,problem )obviously those should be checked , is problems related too the manifold and engine and air heat sensors, those sensors seem to be able to function well enough not to throw trouble codes but not always well enough to allow the engine to run perfectly
THESE THREADS AND SUB LINKS MAY HELP
grab a multi meter and check the sensor resistance and for a good electrical connection

THATS WHY YOU BUY THE CONNECTORS TOOLS WIRE AND LEARN TO WIRE THE CAR YOURSELF!
anytime you price out a car custom wire harness youll be in shock at the absolute absurd prices quoted.
personally Id hit the local salvage yards Id bet you could negotiate the price of a complete wire harness from a fairly new truck for under $200

if you work around older cars for awhile your sure to notice a great many problems can be traced back to faulty, corroded or broken electrical connections, sockets and connectors or fuses ans wiring that need to be repaired or replaced, especially in moist areas, and in many cases youll be far ahead to just buy a new connector and carefully solder it in and use shrink tubing over the splice
having a wire roll caddy , thats easy to access or fabricating one for working around the cars helpful
I can easily see where some simple fabrication skills, some careful measuring and a bit of rough design work on a pad with a ruler and pencil and a quick trip to harbor freight and home depot, to buy a few components , a power drill, a few bits screws and some 1/2" conduit ,a couple 2 foot long sections of 2" angle aluminum,could rather easily result in a rather well designed electrical wire spool holder rack of several types depending on your shops needs
