I just did head gaskets on my D2 got it running for 2 days about 2 hours each day ran great a/c nice and cold i remembered that i still had the 2 bolts for the coil pack that bolts to the top of the intake and the bottom ones were still loose so i tightened the bottom ones and installed the top ones and the CEL came on the codes were 4 misfire codes reset the light it comes back the engine runs fine no skipping so i take out the top bolt and loosen the bottom bolts and reset the CEL light and it stays out non of the wires are caught under the bracket and the green ground is bolted to the intake ware it was any ideas?????????
