heres my problem... for about 2 weeks now my iacv has been acting up. originally i was running my stock y7 manifold on my y7/y8 mini me. started top run like ***, got my hands on a y8 manifold, slapped that on, still ran like ***. checked my CEL codes. keeps giving me a 14. which is the IACV. i did the 3 to 2 wire conversion, reset my ecu, same result. could the problem be that im using an obd2b to obd1 jumper harness? or what else could be wrong. thanks

 

did you try running it without conversion harness?

 

i cant because without the jumper harness the stock y7 ecu i have can only read a 3 wire iacv. i did the 2 wire iacv conversion, so when i tried without my harness, it still ran the same and still flashed code 14.
