I found a very small leak in the vacuum hose that went to the vsv for the dashpot. That is fixed and working properly. I also replaced the iac, grounded the O2 and tested the map sensor. I am still getting a missfire when the ISC is operating. Any ideas on what to check next? What do you think about unplugging the block that sends the signal for the lights and fan?
