An EGR valve can be burned only if either:
1 - there are way too many gases going thru it - check the control unit, it might be keeping it fully opened almost constantly (you will probably gonna have to take the car to someone with a good tester).
2 - the cat is clogged and the back pressure is forcing more gases than normal thru the EGR - replace it
2 - the fuel mixture is too lean and the exhaust gases are still burning - something is wrong with either the O2 sensor or the ECM - again, the car must be tested.

Sometimes the problem is a blown cig lighter fuse if you are using an OBD 2 scanner.

Here's a link to what type of scan tool you should be using.Here's a cool song too.

A normal tune up is plugs/wires/cap/rotor and fuel filter. If you have a DIS (distributorless ignition system) change plugs,wires,fuel filter. You can also change oil and air filter.

does this help?

Hi Jessica,it could be your throttle position sensor,here's a link on how to replace,buy from AUTOZONE,They will refund, if it doesn't solve the problem,let me know.http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?fromSearchPage=true&pageId=0900c152800b85ed&partName=Throttle+Position++TP++Sensor&partId=0900c152800b85ed

Here's how to replace your starter.

Here's a step by step on replacing your head gaskets.

So depending on Engine size, you either have 6 spark plugs or 8. The 6 cylinder doesn't have a cap and rotor, so just plugs and wires. The plugs are a 5/8 or 16mm socket. It is a special socket that has a rubber cushion to try and not break the plugs when removing or installing them. Regardless of 6 or 8 cylinder, you want the car to be cold for this. You grab one spark plug wire at a time, twist it back and forth, and pull straight away from the spark plug. Sometimes this is easier said than done. You want to purchase new plugs and wires, and if your car has a cap and rotor, you will want to get those too. I recall the '93 Z28 has a very expensive distributor cap, over $200 so maybe don't change that. The better brand of plugs come pre gapped. AC Delco is a great brand for Chevy. You want to put antiseize on the threads. Unscrew the old one, then install the new one. My favorite tool when doing this is a 6" wobble extension, as it seems to help with most plugs. You can take a piece of vacuum tubing 1/8" and stick it on the tip of the plug to help install the plugs without stripping out the threads in the engine cylinder head. You can remove one spark plug wire at a time and line it up for length with the new one in the set you purchased. Put Dielectric grease in the boot that goes on the spark plug end. Don't put it on the other side (Coil or distributor cap). Although there are many filters that can be involved in a tune up depending on the mileage of the vehicle, the biggest difference in how a car runs typically is spark plugs.

If you look on the low pressure side of the AC system you will see a plug that is incorporated in to the line. It will have two wires leading to it. Remove the plastic clip that attaches the two wires to the sensor and use a short piece of wire to connect the two terminals in side the plug by putting the ends into the cap. This will bypass the low pressure sensor and allow the AC clutch to engage and begin to cycle again. Remember this low pressure switch is there for a reason. If you don't add more r-134 to the system and allow the AC compressor to cycle you will destroy the compressor. You need to charge the system when you bypass the low pressure switch and get the system up to full charge status and reconnect the switch.

try giggling the shifter or starting it in neutral--possible interlock switch failing. Also could be your anti-theft system--try using other factory key

Check your fuel to see if there is something wrong .

Go under the car and inspect for fuel stains.

If it's the same as the VATS system in my 86 Corvette (resistor pellet in key) the ignition switch might need to be replaced. The contacts on the key wore low, replacing the key helped for a short time but the new contacts wore the switch down faster then it too needed to be replaced. $200!

timing is out of whack have you done anything to the timing... It sound like you have either a plug wires crossed or your timing is out of adjustment.

it sounds like the check valve inside the fuel pump is bad. common on cheap or after market pumps. use a fuel pressure gauge and see if your fuel press drops back to zero. after the car is turned off. if the check valve is bad the fuel will leak back into the tank over a period of time. is the car hard to start all the time. or mainly after sitting a little while. if so this is your problem. good luck .

So my first question is - is the fuel pressure normal at the injectors ?Was the check engine light staying on before the problem occured ?And before you changed the plug wires ?
