codes help 92 sho

I have code 114, act/Iac/vat out of range what will cause this and 225,:headshake:banghead: nok sensor not detected NEED HELP

Have you verified the IAC and knock sensors are connected? These may both have been disconnected/removed when changing the CKP sensor as you've posted elsewhere. Make sure everything, including engine grounds, got hooked back up properly. Also, when you replaced the ECM did you replace it with the same part number?

I don't believe your 92 will the misfire monitors, so you're going to have to do some good old-fashioned troubleshooting. Remember what it takes to properly combust the fuel, compression, appropriate air/fuel mixture, and spark, along with everything in proper time.

You might try doing the the built-in cylinder balance test to see if that reveals a cylinder that isn't pulling its weight.
