186 red motor. Why does it have a missfire under load?


Engine is under max load in the situations you describe, so any weakness in spark or low fuel prssure can cause this, even a weak ignition module.

My 2000 f150 throughts a code . missfire cyl 1&6 but ive replaced every thing i can think of. would a exagost leek cause it to missfire? or a cloged cat


misfires can come from faulty injectors, low fuel pressure in the manifold. timing , blocked exhaust. faulty o2 sensor, leaking inlet manifold gaskets, faulty valves (burnt) It is not always plugs and leads. Have a fault code reading done.

Engine missfire codes compression low


I shudder every time I see the "new engine solution" to a problem ( unkess I read that there was no oil and the engine will not turn over)
you have to know the copmression pressures before you can decide if that is the real reason for the misfires
the compression readings can be as low as 120psi ( down from 165psi for a good engine) and then both a dry and wet test done to confirm engine condition requiring a "new " engine
compression figures can vary 10% between cylinders before it is considered necessary to do something
so move on to other problems
random misfires (code p 0300) can be electronic which is coils , ignition control modules , distributor cap , HT leads , plugs , injector /s wiring and ECM or it can be from faulty injectors( dirty ) low fuel pressure , mechnaical ( loose valve seat inserts
from your description and you obviously are not convinced by the new engine arguement I would be taking it to anoher accredited service center conversant with your make and have them run the fault codes again, check the fuel pressure , and the cat converter for failure and blocking the exhaust
just some ideas to start with

1999 malibu 3.1 clyd 5 missfire and now random missfire oil light is on lfters very noise runs rough


Have you confirmed there is no oil pressure and the oil level is full on the dipstick?

The oil pump is turned by the oil pump drive located under the throttle body. The oil pump drive is run of from the cam shaft. It is not uncommon for the camshafts to break on these engines.

It may not be a bad idea to pull the front valve cover and turn the engine over by hand to see if all the rockers are moving.

My o1 sebring is shacking in low rpm (missfire???)


if it was me i would check all vaccum and change the spark plugs and wire if needed and the fuel filter before you do all of that put some STP in the tank make sure you have over an half tank of gas and if the car try to run better then do all of that remember to take the gas cap off before you change you fuel filter so you do not loose all of your gas
