draw this on a paper
u start with no1 get the valves rocking which means turn engine over by hand til no 1 rockers one rocker is going up and the is going down u may have to turn the engine back and forth slowly
to see it . once u have no 1 rocking u can adjust no 6 valves adjust them with a little clearance so the push rod still spins freely

Fairly common problem. Typical scenario is start vehicle, runs fine
for 15 to 30 seconds and begins to backfire when placed under load as
customer tries to drive vehicle. Flooring usually makes the problem go
away. Usually does not throw a code.
Fix is to replace the upstream 02 sensor.

SOURCE: backfiring and loss of power
'till you do some in depth testing of all systems, I'd place equal weight on every possibility. Make sure you cover the basics like fuel filter etc before getting crazy with it though. Also check cap. rotor, coil and wires. Idle cylinder pressure is different than that encountered when driving. This additional pressure will cause ignition spark to seek a better easier ground,(not the spark plugs where it should be going) causing missing under load.After checking , if you haven't found anything, its time to begin testing fuel pump pressures, modules and controls.

SOURCE: backfire into intake
I'ts quite possible that your distributor is installed one tooth off and is too far advanced, causing the plug to fire before the intake valves are closed completely. Turn it one tooth counter-clockwise and try it again.

Hello osmanmackoy; My name is Roger and I will help you. First have you done a compression test? If so the compression must be over 100 psi. in order for the cylinder to fire. This would be a bare minimum. I would also look at the oil pump drive unit. This would be located where the distributor would have been on the older engines. There is a sensor mounted on the top of the drive. Remove the sensor and check the inner shaft. There should be no side to side play in the shaft.If the shaft moves side to side You need to replace it. This sensor is used by the computer to tell what cylinder to fire. The computer will not know which cylinder is next to fire. This will cause a no start or backfire condition.
Please rate the quality of the answer given as this way we know the answer was helpful. Should you need further help Please just ask . Thank You for using Fix Ya. Roger
