Failed Transmission most likely

How is the fluid level?

This trouble code could be 3 different possibilities...

Code 18 can be any of the following:

DTC 18 ABS Enable Relay Coil Circuit Shorted To Battery
DTC 18 Injector Circuit Malfuntion

Hope this helps...

that means it's not coming thru cap, replace cap

yes the egr is a very persnickity part. the code means that the erg is stuck closed. I would replace it.

Good Luck!

24 is for the TPS and 34 is for the MAP sensor. But not on a 70ish camaro. It has to be 1982 or newer

yes, do some internet searching, I believe there is a control that you unplug inside the hatch on the left hand side, remove the inside plastic panel, undo the connection, wait 5 minutes then reconnect. This I have done once along time ago on a 94 model. Remember I am only here to help and wish this works for you. Good luck.

codes range from 12 to 61...
