I have a 94 with a 302 and have done a tune up and now it barely starts and when it does it sometimes choke off what could be causing this?

 

First check for codes, instructions at the top of this section.

 

What was the extent of your tune-up? What parts were inspected or replaced?

Suggest that if it runs worse after a tune-up, then it's almost got to be something done during the tune-up.

Some things that come to mind are -
* crossed plug wires
* wires installed out of position on the distributor cap
* replacement parts bad out of the box, or the use of bargain-basement cheapie parts.
* something moved or dislodged during the tune-up actions - snapped connector, broken wire, something intentionally disconnected that was not reconnected.

 

if you did a tune up and it runs worse i'd say you crossed plug wires

 

I'd say you've got the firing order wrong........ what firing order did you use? 13726548 or 15426378?
