Though Chevrolet would likely never admit it, the 1967 release of its long-standing muscle car, the Camaro, was obviously due to the pressure created when Ford released the Mustang three years earlier. Just as with all muscle cars of the era, the 1970s emission crunch nearly killed the Camaro. The Camaro hit rock bottom in 1975, as its once powerful 350 cubic-inch engine produced between 145 and 155 horsepower, depending on carburetor options. By 1994, the Camaro began returning to its normal self, as its optional 5.7-liter engine cranked out 275 horsepower and its standard 3.4-liter engine hit 160. Replacing the ignition module on the standard 3.4-liter engine on the 1994 Camaro requires removing the coil packs to gain access.

Disconnect the negative battery cable. Look on the front, drivers side of the engine and find the three ignition coils that attach to the ignition module. Label all six spark plug wires 1 through 6, using masking tape and a permanent marker.
2Pull each spark plug wire by its thick rubber boot upward with a slight twisting motion to remove it from the ignition coil. After unplugging the wire from its connector on the coil, label the coil terminal with the same number you labeled its wire with, using masking tape and a permanent marker.
3Pull upward on the locking tab on each of the three wiring harnesses plugged into the ignition module and unplug each harness.
4Label the ignition coils 1 through 3 from left to right with white marking paint. Remove the two bolts securing each coil to the ignition module using a ratchet and socket, and pull each ignition coil pack upward to unplug it from the ignition module. Pry the three oval-shaped coil pack seals from the coil pack-to-ignition module mating surface with a small flathead screwdriver.
5Pull the old ignition module off its bracket on the engine.
6Slide the three oval-shaped seals over the prongs on the ignition module that the coil packs plug into until they seat in their grooves on the ignition module. Set the new ignition module onto its bracket on the engine, aligning its bolt holes with those in the bracket.
7Line up the coil with the 1 painted on it with the prongs on the far left of the ignition module, then press it down to slide the coil pack onto the prongs. Hand-thread the coil packs two retaining bolts. Repeat this step for the coil marked with the 2, then the 3. Tighten the coil pack-retaining bolts to 40 inch-pounds using an inch-pound torque wrench and socket.
8Apply a small amount of dielectric grease to the inside of the spark plug wire boots and spread the grease around with a small flathead screwdriver. Connect the spark plug wires to their corresponding receptacles on the coil packs and press downward until you feel each one click into place. Remove the labels from the wires and the coil packs.
9Plug the three wiring harnesses to the three receptacles on the ignition module.
