    customer came in for intermittent engine light. i ran a koeo code check = aok ran the koer code check = 173 O2 rich and 213 spout circuit open. a further diagnostic data scan revealed the the vehicle is running rich and will not enter closed loop. all readings of sensor operation indicate normal limp in mode is active ( base run program ). I tested the TFI = aok, inspected and tested spout wiring and signal = aok, problem i must find a test for the computer and hall effect to confirm or exclude. suspect low frequency of the pip resulting in little or no change during spout modification from ECM

My 1988 Mustang 2.3 liter just put new timing belt with new coil does it have to have the spout connector plug that hangs from the distributor?

Yes, the spout connector needs to be in place. It controls the timing advance electronically of the motor based on the RPM. This is why you remove it when you are originally setting the timing, and also why you need to reinstall it after.

How can I adjust time timing on 91 ford F150 5.8L

let the engine get to normal operating temperature, then pull the spout (spark plug out) connector. Then hook up your timing light and rotate the distributor until you're at the timing spec you're looking for. I believe 10* BTDC is the OEM spec for the 5.8. Once you've got your timing set, put the spout back in. and you're set!

Where is the spout connector located on Ford Ranger 1987 2.3L 4 cylinder. and what does it look like.

Hello pennockgaryc: My name is Roger and I will help you. The spout connector will be taped to the wire harness that goes to the distributor module. Will be either grey or black and will be rectangular . This will be a plug that the wire only go to one side. One of the wire that go to the spout connector should be yellow with a dark green tracer. Just pull on the plug and it should pull apart. Set timing to specs of 10 degrees. Reinstall the spout connector and you should be good to go. I tried to send a picture but it was to big for this program. I hope this will be useful. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

The SPOUT connector is used to set the base ignition timing. You unplug the spout, set the base timing to specs, then plug it in. It doesn't affect the plugs or wires.
