Hello,
My daughter's 1995 Firebird with 3.4L is having a peculiar problem. It backfires through the intake when you rev it up from idle. It is not real loud, but minor explosions easily heard and felt when you place your hand upon the air plenum and air intake duct. Seems to be using a lot of fuel too. Low on power.
I changed the timing gears, chain, replaced both heads with rebuilt heads, camshaft sensor, all three ignition coils, plugs, plug wires, and have extracted one code from the computer. It is "36 24X signal error". I looked in my Haynes book and that code says " (36) Faulty circuit error from coil packs to module".
Looking at that code, I rushed off to the store and bought a new ignition module. But, there was no change.
Any ideas would be appreciated.
Thanks,
Alton
