Answers :

Lonnie it could be quite a few problems. I will name off a few .
\015\0121. If vehicle has not been tuned up in a while it could use .
\015\012a) spark plugs
\015\012b) Plug wires
\015\012c)distribitor cap+ Roter
\015\0122. You may need to change out fuel injectors . If you havnt done any of these things in a long time (over 12 months) they are probably the problem and if it isnt the problem you didnt waste any money because they needed to be changed out anyway. I hope that you rate my answer because if not i dont get credit for them. Thanks and have a blessed Day.
