Ok I have a 95 VX hatch with a 95 EX motor swap (D16Z6). It all ran fine no CEL's no noticeable issues. Two days ago a coolant line split (the heater line under the dizzy) and the car over heated a little for a few seconds. I replaced the hose and the air filer, checked the oil (it was low so I added 1.5 quarts), washed down the engine bay and filled the coolant back up. When I fired her back up she stuttered and hesitated on acceleration. I checked the TC's in the ECU and got a few. One was the O2 sensor and I had a spare so I threw that in there, reset the ECU (removing the 7.5 amp back-up fuse under the hood) and tried again. Same crap but the O2 sensor and a couple other TC's went away. The only TC that was showing up was the MAP sensor (TC 3), so I replaced that and went to bed cause the nieghbors were bitchin'. This morning I got back at it and after I cleared the ECU (using the above method) I fired her up, no CEL and she seemed to be running fine again. I took her about 5 miles down the road and when she finally warmed up the stuttering and hesitation came back. I tried to check for TC's but when I short out the diagnostic plug (under dash by the ECU) the CEL just stays on. Now I don't know what to try and I need some help
