1994 Corvette hunting problem

20

Asked by Aug 23, 2010 at 10:28 AM about the 1994 Chevrolet Corvette

Question type: Maintenance & Repair

I own a 94 and it only hunts when its warm. We changed the ecm, checked for vacumn leaks, bypassed the egr to see if anything can stop the problem. We made sure the IAC was clean and working porperly. Something is telling it to surge to 150 after it heats up. The shop has been working on this for over three weeks. We are now checking to see if the o2 sensors are bad even tho they are reading that they are fine. Any feedback??
