MISFIRE 1 AND 4

Well lets get in there and investigate the filter/pick up screen-blockage within the fuel lines-the fuel pressure gauge will tell you if its producing the correct pressure and whether the fuel pump /regulator/fuel filter are doing its job.

I agree with the valve seat issue. it is common for those heads.

i bet if this issue is resolved, your problem will be gone.

Thankyou for the help

i think it is the filter screen blockage
will look tommorow

thanks for the help

Thanks for all your help. I will remember next time I'm working on a car that has similar age and mileage to check the compression early on in troubleshooting. Take care, Jerry

good luck
