EatingSparkPlugWires
So I've got this 2.8L 89 Camaro that eats up the spark plug wires. It seems like as soon as I replace them, they go bad. It always seems to burn up the boots on the end. What the heck is the deal with this? Also I've got the intermitent code 32, could this be a part of the cause? And one more question, my hatch pull down is messed up. The light back there just stays on, and the it's stuck in the down position, so it won't even come up so the hatch won't go in.

Blue,
I'd suggest that you install a set of AC/Delco wires, and if you've lost the heat shields, order new ones at the same time. They look like this:
The intermittent code 32 is an EGR system error. On a V-6 and most TBI engines, this is caused by the failure of the MAP sensor to detect a vacuum change in the intake when the EGR is supposed to be opened.
The ECM operates the EGR vacuum solenoid, the vacuum source operates the EGR valve, and the MAP sensor detects the operation of the valve from the slight increase in absolute pressure (decrease of vacuum) in the intake manifold. The problem could be with a failed or disconnected vacuum solenoid valve, failed or leaking vacuum line, stuck or failed EGR valve, clogged EGR ports in the intake, or a failed EGR valve.
Good luck.

Blue,
You may have to disregard some of that first reply. The spark plug wire information is correct, but since you have an '89 MPFI engine, you may have an EGR solenoid with a four-wire connector.
If you have a four-wire EGR vacuum solenoid valve, the MAP sensor is not used to detect EGR operation. There is a vacuum switch in the EGR solenoid valve which detects vacuum to the EGR valve. If this has failed, you will set a code 32. The other possible causes are still valid - vacuum hose leaks, failed or plugged EGR, or a failed EGR solenoid.
If your EGR solenoid only has a two-wire connector, the MAP system is used and you should use the first reply posted as your guide.
Sorry for the possible confusion, but I wanted to cover all the bases since I'm not sure what system you may have.
I would suspect that the ECM is working in either case, since it is apparently trying to operate the EGR and is reporting an error code.
