Troubleshooting the ignition timing on a 2002 Mustang 3.8L V.
Engine starts and idles okay. As it accelerates, it tops out around 30 mph, stops accelerating and runs kind of rough. You can hear an occasional pinging which sounds like pre-ignition valves clatter.
Everything else seems okay, just won't accelerate, no power. I'm guessing ignition timing out of whack.
Re: how to set the ignition timing on a 2002 Mustang
TIMING IS ADJUSTED BY THE ENGINE CONTROL UNIT SO IT SHOULD'NT NEED ADJUSTING.ODDS ARE THAT YOU CAN'T GET RID OF EXHAUST FAST ENOUGH DUE TO A PLUGGED CONVERTER.

18-22 DegreesBefore top dead center - When throttle positionsensor disconnected and using suitably programmedscan tool.When adjusting idle speed, set parking brake & chock drive wheels, curb idle speed (750-850 RPM)transmission in neutral.

no-- plugs will not be the problem. More likely a vacuum leak from a hose left off somewhere. If a carby engine it will be the idle mixture screw out of adjustment check ignition timing is set at the correct advance point
engine wont start cold or hot could be fuel problem.check for fuel or spark.try doing little troubleshooting make sure sparkplugs and wires good condition.fuel filter been changed.engine need fuel and spark ignition to run.turn ignition on listen for fuel pump operation in fuel tank if no check fuel pump fuse and relay.if fuse relay okay.problem could be the fuel pump but first use code scanner look for PCM, CRANKSHAFT POSITION SENSOR,CAMSHAFT SENSOR AND DISTRIBUTOR IGNITION FAULT CODE.MAKE SURE YOU HAVE FUEL INTANK I SEEN THAT HAPPEN BEFORE.
Hi Try to check these things first: Check the fuel supply to your engine. If that's okay, check whether the electrical spark is getting to your spark plugs. If still having issues please check this link http://www.dummies.com/how-to/content/troubleshooting-a-car-that-wont-start.html Thanks
All EFI (electronic fuel injection) engines idles high during start ups. It serves like an auto choke to regulate the vacuum supply and most of all to lessen the wear and tear of the engine. Please drive the car only when it reaches the normal operating temp.
Hope this helps and thank you for using FixYa! Have a good one!
Locate the crankshaft pulley at the front of the Altima's engine and clean it off to expose the timing marks. Start the car and turn off any accessories such as climate control, lights and the radio. Allow the engine to idle until it reaches normal operating temperature.
Turn off the engine and connect a tachometer to the distributor per the manufacturer's instructions. Connect the timing light to the battery and then to the number one ignition wire. Start the engine and verify it's idling at 1,000 RPM. Adjust the idle speed if necessary
Point the timing light at the crankshaft pulley to determine the amount of adjustment needed. Adjust the timing by loosening the distributor mounting bolts and turning the distributor until the crankshaft timing mark lines up with the middle line of the timing light.
Tighten the distributor mounting bolts and recheck the timing. Turn the Altima off and remove the tachometer and timing light. Reconnect the number one ignition wire.
Ignition timing should be set at 10 degrees BTDC (before top dead center), with vacuum advance hose disconnected and plugged, engine idling at 800 rpm or less.
CHECK FOR OVER FILLED OIL LEVEL,DAMAGED BALANCER,LIKE DOES IT WOBBLE WHEN RUNNING OR PLUGGED CAT'S, THESE OLDER EEC IV IGNITION WONT NECESSARLY SET A CHECK ENGINE LIGHT WITH A IGNITION MISS. DID YOU WET THE CAR,IF DID MUST REMOVE ALL WATER,NO MOISTURE AT ALL. TRY PULLING OFF ONE WIRE AT A TIME AND SET IT IN A SAFE LOCATION AND RUN IT,SEE IF PROBLEM MOVES OR NOT. IF NOT ON A PARTICULAR WIRE THAT MAY BE YOUR SUSPECT.
Do you have an Oil Pressure gauge? If not you may want o have one installed (even temporarily). After the vehicle sits overnight, start it and see how long it takes to get pressure. If it is the same amount of time that the engine knocks, then you may want to start looking for another engine. If oil pressure is okay, you might have a bad wrist pin, which can make noise for years without any other problems. Now if the noise is a "ticking" then.............
the engine compensates for the load try turning up the idle screw also check the ignition system you might just need new wires and or cap rotor or your coil is bad also plugs
