Hello, I am Danny.

Just a few quick questions first. What kind of "tune-up" did you do? Did adjust the timing on the distributor? Let me/us know. We are here to help.Thanks for using 2CarPros.

Just replaced basic parts. Nothing was adjusted (not that mechanically inclined). I replaced spark plugs, wires, distributor cap and rotor. Along with all the filters I could.

Hello again.

Did you double check to make sure all plug wire connections are firm and clicked/snapped correctly into place ? Sometimes something that easy makes all kinds of problems. Let me know and thanks again for using 2CarPros.

I did, turns out that before I did the time up the distributor rotor was starting 180 degrees from what it was suppose to be. The engine was rough before the tune up. So when I put the new parts it just got worse. Ultimately the fix was as simple as turning the ignition enough to move the rotor without starting the engine until it moved back to position one. I am not sure if I explained it well enough but long story short I fixed it. But I did want to say I appreciate the time you took to help me out with this. Thank you.
