93 Lumina 3.1 6 cylinder with 136000 miles with ECM telling it to idle to high and to low. Also is running on only 5 cylinders instead of 6. Any ideas on how to get this fixed for fairly cheap. :banghead: :feedback:

Have you tuned it up recently (changed the plugs, wires, pcv, etc...)? If not, try that first.

New Spark Plugs and Wires had it in the shop today to run a diagnostic and said needed new ECM and was only running on 5 cylinders. Don't even know what the pcv is.
