My 97 Camaro (V6) threw 3 codes this morning, had them read, has anyone had the same problems? Can you give me some insight?
-Code: P0300- Random Cylinder Miss.
(explains, Ignition system fault-possibly spark plug(s) wire(s), possible coil, vaccum leak, injector fault
Has anyone had this?
-Code: P0121- Throttle Position Sensor
(explains, sensor open or shorted, to replace component, or to check connector and wiring)
???
-Code: p1406- Valve Pintle Position Circut?????
(explains, says the EGR Pintle Position was 10% of the expected position, failed EGR valve?, open or short circut condition???
Ok these are the codes and explanations from the computer, I am fresh to the Camaro, please please help me

 

While most people thing that the P0300 code means ignition system problems, it actually is rarely an ignition system issue and usually an air or fuel problem. If your EGR valve is opened when it is supposed to be closed you will cause multiple random misfires (P0300) and also if your TPS is not reading properly you will get erronious fuel mapping conditions (again it can cause the P0300 code). I would look into fixing the TPS and EGR before playing with the ignition system.

As Massey said. Multiple random misfires are usually dut to a lean condition. Bad EGR and TPS could cause the problem.

 

I did realize Monday ( I bought the car about 2 weeks ago) the vaccum line end had tape wrapped around it, also, when I went to put my new thermostat in Sunday, I take the housing off, NO Thermostat! Sooo I put my new one in. I recieved the end piece for my vaccum line, put it on (because one of the codes reccomened checking the lines. Check engine light went off on the way home, but the car is still randomly missing. I work for Chevrolet, so how about a possible EGR delete and computer retune???

 

thats a possibility while your at it maybe a cat delete too
