you never said fuel filter. or if service engine soon lite is on.try filter if problem persists check compression if ok possible pickup coil and or control module.mybe its my mistake but is ses lite on if not it still comes down to air fuel combustion. back to the gap of the spark plugs. are the wires a good brand same with dist cap and rotor check all before if you bumped the dist. very unlikly unless you loosened the hold down bolt.is the dist a nondisturbed type or disturbed ? that's a timing issue ok.Answermake sure your distrubutor didn't get bumped and is causing crossfiring,just went through that and it will cause SES codes that aren't necessarly true.truck would sputter and sometimes backfire at low rpm's.you need a special diagnostic tool to acuratly set the distributor that displays the degree of the camshaft,i believe there's a mark on the underside of the dist. and a mark on the intake manifold to show if they are set right,but what i did was loosen the hold down bolt on the dist. and turn it all the way to the left that it would turn.then i would just bump start the ignition and then turn the dist. just a hair until i got it to where it would fire up with just the slightest bump on the ignition.there may be a better way to do it without the scanner tool but that worked for me.hope it helps.
If you have spark at all but one plug, the problem is with that plug, wire, cap or rotor.
When you replaced the plugs, did you check the compression? Did any of the plugs look different than the others? Low compression in one cylinder can cause misfiring. But then, so can a faulty distributor cap.
yes it has a cap and rotor. its just located on the front of engine a timing chain cover. it has 8 pins and can be replaced. Also rotor can be replaced.
change distributor cap and rotor
Code P1399 means:Random missfire Plugs not gaped right might want to check them since you just replaced them or plug wire loose?
You may have messed up the firing order. Need to know what engine and year you have to help you.
What year? What engine? Spark plugs or rotor? A more specific question is required.
Go ahead and replace the pcv
You don't. It has a D.I.S. ignition system and has no distributor or rotor. There are three coils mounted over spark plugs under coil pack cover (center top of motor) Each coil fires 2 pistons. They are not replaced as a tune up item. They are only replaced if faulty. Spark plugs should be replaced every 15,000 miles.
Your float is sticking
depending on the engine size they will be located in the sides of the heads. look for a rotor cap and 6 or 8 big wires, depending on the engine, then foller them rihgt down to the spark plugs.
It sounds likes it's your voltage regulator malfunctioning.
Bad coil? Bad coil wire?
my s- 10 did the same thing i replaced to dist cap rotor and plugs it helped
(Magnetic pick-up) Inside the Distributor.
Your coil needs two things: power, which you have, and a trigger(i.e.) a hall effect switch or a camshaft sensor. Without a trigger it will not spark at any plugs because its not being told to. Hope this helps you out. If that doesn't work then try grounding your engine more to the body if you haven't already.
check and see if u have a hole in your muffler
Check the coil and replace if bad. Should fix the problem.
Check and clean spark plugs distributer and rotor change air fillter and oil change wont hert
try checking youre timing
have you tuned it up? plugs, wires, cap + rotor
This website should help. Good Luck! http://www.aa1car.com/library/misfire.htm
Have you connected a code scanner? What is it saying is the problem?
full tuneup, plugs, wires, cap/rotor, air filter, fuel filter etc.
