engine is misfiring injector circuit open cylinder 3 what do I do ??

6 cylinder

As best I can remember - on the 4.0L .. Cylinder # 3 injector connector/wiring is prone to contacting the throttle cable mounting bracket and may have caused that problem due to wire chafing .. I feel sure a 'mechanic' would have noticed that .. Do you know if # 3 cylinder has injector pulse from the wire connector when tested with a noid light? Sorry but that's the kind of information we will need to proceed... Perhaps you could ask the mechanic .. I know a trick or two that may help, even IF the # 3 injector driver circuit has failed!

What's the trick he tested it the light went off n he didn't say anything else about it but it car back on car is running good except for the jerking n misfiring
