Question about Cars & Trucks
No online editor sux ,huh? but i get your drift.....
CEL flashing (read the op guide, it tells you) This means
the CAT is now overheating, (due to vast raw gasoline influx)
That is a USA rule, (not done on true Canada cars)
that flashing is a special rule with USA OBD2 ECU's
and 2nd, ? is the CEL glowing driving, and idling??
yes, then pull the codes the DTC errors. using any scan tool.
(all my answers are USA, so if not in USA. say so)
The misfire code for cylinder 1 is P0301. see that 1 at the end means just that.?
there are 3 tests to find this, all mechanics, know this.'
1: spark on #1 is DEAD. (or very bad) test spark.
2: compression #1 is bad, not 150PSI min.(a cheap gauge tool)
3: injection on #1 is bad. (leaking>? or clogged or dead) more gauges, tools, (leak down test is top of list for injectors as is NOID test and resistance of the coil) etc.... read the fSM
or go to alldata.com and read the reasons for P0301.

You may have a bad coil pack - try moving two of them around and see if the misfire follows the coil pack or stays at the same cylinder. If it follows the coil pack, get a new one. If it stays in the same cylinder, inspect your spark plug wires and make sure the plug is gapped correctly.

SOURCE: 96 firebird is having problems,
Have you ran a diagnotic check to see what codes are coming up?
Throwing parts at the problem will get expensive. It will also ruin other parts (Like your catalytic converter), when your engine is misfiring and not running properly. Your vehicle is an OBDII system, fix the problems in the order they appear (then clear, run and recheck)...meaning, one problem can cause another and so on. Fixing one problem may correct the other ones too.
You may get lucky with the shotgun approach, but usually not.
Run a diagnostic test, at least you'll know where to start looking for the problem.

The only thing left is the injector or a vacuum leak on the manifold gasket sucking air in and causing a lean condition. Thats is its the only common issue providing you dont have a head gasket issue leaking coolant on that cylinder and the compression and valves are not leaking. The old spark plug should show a coolant issue if present. The white part will be shiney if you have a coolant loss. If the coolant is looking real dark you should have the cooling system checked for gas being pushed into the cooling system on compression stroke thru the head gasket.
