Just bought myself another camaro..its an 1988 iroc z with this engine..

383 Chevy Small Block 350 Horsepower Corvette Engine


kid was having interior electrical problems and i picked it up for 1k

I had it started for about 10 seconds..then she stalled and now shell just keep cranking but won't fire. Im not getting spark from the coil wire. I changed the coil and wire that leads to the dizzy..nothing. I tested the ignition module at my work, came up good ( not the most accurate test though, so this may be the culprit).

And this vac line i found just hanging around..On my speed density (92 z28 350) it leads to a three way junction by my map sensor..im not sure bout this car.. Here is where the line begins..



it wrapped around the intake but i dont see anywhere for it to go..

 

that line looks to me to be for your heater. im only guessing here but on mine it is connected to a largeish ball just behind the front bumber. again i may be wrong but i just thought it may help out a little. hope you get it sorted.

 

That line wraps around by the intake to a check valve along with the hvac hose. then the check valve follows a short fe winch line into one of the 2 holes on the plenum.

 

ok so it is the same as my 92....i guess it was cut off or something and they replaced the check valve with a straight plastic connector..
