The codes degraded to 33 and now 34 so I installed a new MAF which did not help although it went back to only code 33. Somebody suggested that I upgrade my ECU to an 87-89 memcal so that my computer will communicate at 8192 baud instead of the agonizingly slow 160 baud I have now. So I'm looking for a 87 vette Memcal ($32B) for and automatic with 3.07 gears. Would someone be able to burn one for me?
