1994 Civic Si with lumpy idle
Hello
94 Civic SI. 150,000 Mi, with JDM ZC engine (Certified 35,000mi). Purchased the car from a friend and replaced the engine due to small hole in block from connecting rod problem. I have been driving it for a month with no problems, always starts right up. Recently, if I start the car and drive a short distance and hit a red light, the idle lumps between 1,200 rpm up to 1,800 about every 0.5seconds. After it has warmed up a bit, never a problem again. No engine codes. I was thinking maby some fuel injector cleaner is in order. Has anyone had this problem?
