Hello all,

I am at my wits end trying to solve a wild idle problem. The car idles fine when I start it and runs for about 20 minutes, then when I am sitting at a light or crusing down the road, the car seems to lose power or the idle is bouncing from 1000 rpms down to almost a stall. I have replaced the exhaust manifold seals, the O2 sensor, ignition module, fuel pump relay, fuel pressure reg. Engine check light came on with code 1 1 3 which is lean or rich mixture. Could it be a bad fuel injection relay? Tired of trying to hunt this problem down. Plugs, wires, dist, IAC, all new. Any help out there would be appreciated.
Mike
