new to tuning, have hptuners, and 0101 code
Car is an 86 Monte, 5.3, ls1 intake, long tubes, cold air, and lq4 cam. Has a 5 pin maf, harness built by Modern vintage. Seems to run fine in open loop, closed loop runs rough, current tune is a mail order tune from modern vintage. Advice on where to start?
Is this attached correctly?
