Clean all the posts and plugs. The 3.8L engine has a common problem with intake manifold leaks.

Best to do a fuel pressure test, pump might be weak and dosent show up until it gets gets warm. Best to do the test after it quits again when pump is at its hottest. If you havent done it yet chg. fuel filter too.

SOURCE: car idles rough in park also runs rough in overdrive

Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.

2000 buick lesabre runs rough, black carbon on one coil post when removing plug wire.


The coil may be bad. Was the plug wire inserted all the way in? Could be a bad coil, but also check that wire and its spark plug for any sign of damage. Not likely, but check.

1997 pontiac grand am with no. 4 cyclinder misfire


What have you checked so far? What engine? Check spark plug for ware, cracks and carbon tracking. Check the ignition wires for damage and voltage leaks, this could be done by spraying the wires with soapy water. If the car runs rough or you see arching replace the wires. Check for spark and check the ignition coil and replace as needed.if you still having problems you may have to check the injector or perhaps do a compression test.

96 Z71 new coil,ignition modual,plugs,wires,cap&rotor,spark from coil,no spark at plugs


Hello: Remove the distributor cap. Check the rotor, see if there is a black spot where the metal piece makes contact with the carbon stick out tha makes contact with the coil. Did you replace that piece when you replaced the coil, it should have come with the new coil? Also did you reinstall the ground strap that was under the coil and went to the stick-out that the black connector plugs into the cap?

Ignition coil wires how are the wires put back and how do i check for problems if the car does not want to start( vw fox 1600).


The firing order is 1,3,4, 2. Look at your distributor ,, there are four connectors on the ouside on the distributor cap and one in the middle. The coil wire goes in the middle. The #1 spark plug connector usually is the one that is closest to the master cylinder,#3 is closest to the rafdiator,#4 is closest to the front of the head and #2 is closest to the rear of the head. make sure rotor and distributor are carbon free. Other wise it may not start and if it does it will run rough. Replace if the items are full of carbon

Random multiple misfirings


Here is a list of possible causes. You should not drive the vehicle if the check engine light is flashing all the time, you can cause even more damage. It could pay to have a professional find the real cause.

Spark plugs that are incorrect for the application, cracked, improperly gaped or worn can cause the engine to misfire or run rough at all times.
An IC module that failed to correctly control the ignition coil(s) will cause the engine to misfire or run rough at all times.
Poor connections, broken wiring or wiring that has shorts to ground can cause the engine to misfire or run rough at all times. NOTE: Check connectors that might be pulled apart as the engine flexes or wires that short to ground as they pass near brackets or shorts to ground on the exhaust manifold.
Fuel injector(s) that are shorted, plugged or partially restricted can cause the engine to misfire or run rough at all times.
An ignition coil(s) that has low output, corrosion on the coil tower(s), is carbon tracked or arcs to ground will cause the engine to misfire or run rough at all times.
A PCM that failed to properly control the injector or ignition timing will cause the engine to misfire or run rough at all times.
