misfire on adjacent cylinders in the firing order.
Overheating due to coolant going to the reservoir and not coming back to the radiator because of the bad cap.
The distributor cap is important to the performance of the car's engine. Some symptoms of a bad distributor cap are stalling, backfiring, shaking, and a high pitched squealing noise.
your radiator clogged up.cheaper to get a new radiator. nothing to do with the radiator cap.
The cylinders will misfire making the car run very poorly. Probable hard starting as well.
bad cap or rotor first thing to check
install new plugs and wires a new cap and rotor it will stop the prob you are having
I can think of three things. it could be a bad distributor cap and or the rotor. the wire going from the coil to the distributor cap could be bad. the coil itself could be bad. check the wire running from the coil to the cap and make sure its properly seated, that's usually what happens to me after some hard wheeling in mine.
youhave a bad water pump or it is going bad. you are not using anti freeze 50/50 with water or thermostadt is bad. worse sanerio is a cracked head.Look under the oil cap if it a cream color or tan color then it is getting water inside the engine.
most likely it could be your wires going bad! or a bad cap.
most likely going to be a bad valve cover gasket although it could be a bad seal on the oil cap
pull the plugs out one at a time, place them back in the plug wire, crank the engine and see if you have spark to each plug, could be dist, or possible plug wires bad...
Bad seal Bad spring Bad neck on radiator
