Hi, you may have a burned exhaust valve. Recommend you run a compression test.

Please see my tip at http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

    Hi, you would have to remove the cylinder head to see the valve. That is too much work unless you have verified the cylinder is lacking compression. So, you can either buy or borrow a compression tester to check that first. Just follow the instructions in my tip post above to run the check. Then, if compression on #1 is much lower than the other cylinders, you would remove the head to inspcet the valve. OK?

Diagram or picture of where the spark plug wires go into the distributer on a engine number 318-1


For this you have to determine when the #1 cylinder is at TDC (Top Dead Center) - when it would be firing. Take the distributor cap off and look at the rotor - it would be pointing at the #1 spark plug wire on the distributor. The wires would be connected it order around the distributor cap starting at 1. The sequence is 1-8-4-3-6-5-7-2 in a clockwise fashion.

How do i find the posiyion of 1st cylinder to put in new distributer for a 98 4.3 blazer distributer wasnt marked when took out


pull out number 1 plug and put a straw or soft object in hole. turn engine by hand on front crank. when the straw or similar is on the very top, just before it goes down ! this is top dead center, then put in distributor with the rotor button facing the number 1 wire on distributor cap, replace number 1 plug and adjust the distributor, buy turning it after it is installed in vehicle.and vehicle is running. if you do not know where number 1 plug is. call the auto parts store. they should be able to tell you. auto-zone etc. good-day !

I mixed the distributor cables up,so i need the order to correctly connect


If the wires are still in the distributer, AND, if you have a stock intake manifold, the firing order is on the manifold. If it's a V-8, the number 1, 3, 5, & 7 plugs are on the drivers side of the engine. The number 2, 4, 6, & 8 plugs are on the passenger side. The number 1 plug wire can be located by looking at the distributer from the front of the engine and visually looking between the distributer and the number 1 plug. Visualize the distributer as a clock. The number one position should be located between 4 and 5 o'clock and should have the longest wire of those on that side of the distributer.

If the wires have been pulled from the distributer, then, then, remove the rotor cap, turn the engine over slowly until the rotor is pointing to the number 1 plug. Using the firing order on the intake manifold, starting with number 1, replace the wires going clockwise around the distributer.

Toyota 22r 85 want to know should I point the roter to the number 1 plug or to the number 1 on the distributer


Point the rotor @ the number one plug position on the distributor, but be sure that the number one cylinder is @ top dead center (all the way up).

Engine runs slowly even tho ignition is switched off.


does it sputter and kick while it is shutting down? This sounds like a timing problem. Your timing may be to far advanced.
To fix this, there is one single bolt at the base of the distributer that holds it in position. It will probably be a 1/2 in bolt or 9/16ths but being toyota may be 10 or 11 in metric. Put the emergency brake on and make sure it is neutral or park if automatic. Start the car. While it is running loosen the bolt at the distributer base and turn it counter clockwise just a hair or two. You should mark the spot with chalk or crayon where the distributer is located before you move it incase you need to return it to the original position. Listen to the idle while you turn the distributer to lower the idle just a little but making sire it still runs smoothly. The car should be warmed up before doing this. Take it for a drive and make sure it was not turned to far and you still have a smooth drive with no missing or hesitations or wanting to quit while stopped.
If this does not cure the problem then put the distributer back to it's original spot that you marked. It may be an ignition switch going bad on you and is allowing electricity to continue to flow to the coil after the key is off. The switch may need to be replaced.
I hope this is of some help, Keep me informed, The Raz

I have a chevy 2.8l engine I just installed and it won't start. I have checked to make sure that I am not 180 off, and I have spark and fuel. the chiltons manuel shows the distributer with the #1 wire on...


# 1 cyl. is on driver side front . remove # 1 spark plug and put your finger over spark plug hole and have somebody bump the starter over . when the cylinder air blows your finger back that is close to tdc. #1 compression. The timing mark on crank might be off a few degress . turn crank to TDC. MARK your distributer should point to # 1 on distributer cap . if not reset distributer.
