here are the symptoms, what is it?

LT1/LS1 maf will require some version of MAF Translator from Full Throttle, and the adaptor harness to make it 'plug and play', which is not cheap. You'll need to figure out your best option of factory replacement type vs. lt1/ls1/translator based on your wallet.... :wink:

The MAF translator (not MAF translator plus-My powerlogger and chip eliminates this translator) was purchased from Turbotweak-~$190. My setup is a direct replacement for the stock 86/87 MAF setup with no additional wiring harness,s . The connectors come with the MAF translator and is plug and play. Take care= Brad
