A few things spring to mind.
Are you using the spark plug from the dead cylinder to check for a spark?
If no, try the plug make sure it's not the plug itself, if yes, check the HT lead is not shorting when it is in position, if the spark plug hole sleeve is deep it may be shorting through the rubber boot that normaly fits over the spark plug.
Are you sure the injector is working? fuel rail blockage, dirty injector, faulty injector, faulty electrical contact to the injector.?

Check the distributor rotor and the contacts on distributor cap, check that spark plugs are not dirty with oil, even if they are new.
If distribution is electronic take it to garage for scanner test.

Does low compression on a 3.1 litre 1999 cause a p0303 code?


Could be a fuel injector, as long as you are getting around 150PSI in that hole I wouldn't think it would register a miss fire.

Why is there a miss in cyl. 1 that only occurs at idle speed, which seems low (750 rpm)?


Bad head gasket, burnt/stuck valve, or bad piston rings. Do a compression test. None are worth fixing in a high mileage car. It only creates other problem.

1999 v6 firebird misfires on #6 cyl when under load, plug was fuel fouled last time I had it replaced, but keeps missing only when under load. no other problems.


if you've changed the spark plug and no difference, then it's time to swap the coil with another cyl. coil and see if the miss goes to the other cylinder, if it does'nt follow to other cylinder, then I would replace that injector !

You said compression is good then i would say you may have a bad coil , unless one coil runs all cylinders, but could still be a coil,,next thing i would check would be the injector make sure it gets a pulse if it does then try switching injectors from that cylinder to another cylinder and see if the weak cylinder changes with the injector change, if it does then you have a bad injector,

I have a dead cylinder. Missing badly. Has spark. Located the cyl. Pulled the injecter from that cyl. and switched with another. That cyl. still dead. Checked the valve springs. look ok. WHAT now?


Have you checked the valve adjustment for that cylinder? Is the cam opening the valves OK? Take the spark plug out, is it bad? oily? Check the compression. should be 120-150psi.

Timing belt broke changed it engine is missing. could it be


The easiest way to test this is to carry out a compression test. This test will determine if any valves are bent. The test is very easy to carry out. 1.obtain a compression tester. 2. remove all spark plugs. 3. screw tester into spark plug hole. 4. with your foot on the accelarator, crank engine. 5. read the tester reading and write it down. eg. cyl 1 175psi cyl.2 170psi etc. if you have a bent valve one cylinder will be very low compared to the rest.
