I am sorry for the long wait

does the check engine light come on ?

do you know if there are any codes set in the computer ?

has anything been done recently to this car that this problem has started to act up or anything done to correct this issue yet ?

no engine light,my scanner is a obd2,this car is obd1 right?I guess i could go to auto zone to get the code
Expert:  Gary replied 1 year ago.

if the light is not coming on then the odds are there are NO codes set

the most common issue with these 5.7 engines are the optic spark distributors behind the water pump that cause this kind of issue

the best action to take is to change the fuel filter spark plug wires and spark plugs

if it still acts up then replace the distributer behind the water pump

these is not much more that will cause a miss intermitanlty
