car starts fine idles a bit rough accelerates to about 30 then wants to cut out

A 'real' sanner with live data needs to be connected and viewed by a real mechanic while vehicle is being driven...fuel pressure test guage can also be connected for this drive!!! .... OR you can just keep on guessing at it!!!!!

I would start looning toward a fuel pump issue test the fuel pressure at the rail also possibel bad gas, i had a grand am do this got water in fuel, pressue tested fine but bad fuel flow, i replaced the pump and also the plugs ran great after that it. U might wanna check your fuel qaulity
