Take a couple of minutes and move the #4 sparkplug to another cylinder to see if the miss moves with it; I have had more than a few bad plugs over the years with cracks in the ceramic and in one instance, the platinum thread of a Bosch plug actually fell down onto the ground electrode.
I don't understand your valve clearance number of + - 3000? If the valve clearance is way off. you won't find decent compression either.
BTW, I drove Fiats for 34 years; '67 124 (terrible car), '71 & '74 128, '79, '80, 80 Stradas, '80 X1/9 and now have as a summer fun car. '87 Bertone X1/9. Loved 'em all except for the first one but maintained all except the first one.

I have a 1988 Yamaha Phazer 500 and it is not running on one cyl. Checked spark and good on both cyl and it has 130# of compression on both cyl


If spark and compression seemed good you may need to check the fuel. I would assume that cylinder has its own carburetor. Make sure it is working by spraying some starting fluid through the intake while the engine is running. If the cylinder starts firing you have a carb issue. The often gum up from storage or poor fuel.

2005 mercury mariner 4 cyl. starts then stalls, won't restart for prolonged rest period


did you use fuel addetive to stop fuel in carbs going off when you laid it up and winterize the cylinders etc ? check compressions , sparks and fuel is in all carbs as if you have sparks then carbs need stripping and cleaning ie, jets and float needles ! compressions to be no less than 100 psi on all 4 cyls !

rpm will drop when u pull a spark plug wire, i'm assuming this does not happen when u pull # 4 plug wire. This tells me # 4 jug is dead, no compression and not firing.

My crank shaft is rotating twise the crank shaft. HOW MY 1342 FIRING WILL OCCURE?, I can spare only 30 digree for charge and spark plug contact. THERE ARE ONLY 2+2 CYLINDER. 180 DIGREE APPART KINDLY REPLY...


Your crankshaft turns 2x times the camshaft. Put it this way as # 1 cylinder reaches TDC (top dead center) of the firing/compression stroke, and this will be after a (8 degs BTDC) spark to ignite the air/fuel mix, the # 3 cyl. will be at BDC of the intake stroke and as #1 begins its power down stroke, (during explosion of air/fuel mix), #3 begins its compression up stroke, the #4 cyl. will be coming down with #1 cyl. but #4 will be in the beginning of its intake down stroke, and #2 cyl. will be coming up with #3 but #2will be in its BDC of the exhaust stroke. Which has just fired previously to #1. 1342134213421342 etc. Now the cam turns to open / close the valves; In the outline above, #1 cyl. valves will both be closed. #3 cyl. will have the intake starting to close at this point. #4 cyl. will just be starting to open its intake valve, and #2 will be starting to open its exhaust valve. Is all this clear as mud? So as the crank makes one full rotation (in a 4cyl. engine) only the firing of one cylinder has happened.and at every rotation one cyl. will fire. So #1 at TDC then one full rotation, #1 back at TDC, but this TDC is half of its 4 cycles, (1)Intake, (2)compression, (3)power, (4)exhaust. this 1234 refers to the 4 cycles of the rotation not firing order.

99 dodge caravan #4 cylinder misfires, i replaced spark plug wires and spark plugs. Scanner showed #4 still misfiring, could this be the coil?


It could very well be a bad coil pack,or you have low compression in that cylinder.If the compression is good then go with the coil pack,if not you may need a head gasket or an intake manifold gasket.

Not firing right on no.4


First check plug and make sure the right plug for this vehicle,make sure that the heat rating for this plug is correct. Your problem could be a wrong heat rating plug been installed. Also make sure that the misfire is due to a bad plug and NOT a bad injector or injector wiring or uneven compression or even bad coil. Check injector wiring and make sure it not shorting or broken. To check injector pulse use a NOID light can be bought at almost any auto parts store like Auto-zone etc. Also compression can be checked with compression guage. A rule of thumb to go by is if any cylinder has more than 10 PSI in difference in compression there is a problem like a burnt valv etc. Here is a n example cyl# 1 170psi cyl#2 176 psi cyl#172psi cyl# 4 150 psi, there is a problem with cylinder # 4 and will cause a miss from cylinder #4. Good luck and thank for using FIX YA

92' Cavalier 2.2L 4 cyl. runs but has a miss coming from #4 cyl.


Matter not whether plug fires out of engine. Put it back in and clamp a timing ligh to it. If the light won't fire, you don't have enough spark to fire cylinder, hense miss.
