5.0l feels like its choking or starving under accelerating

[crisp5.0]

hi guys had a problem with my vt 5.0l cutting out and not starting after it had been running got my dizzy replaced that fixed that problem now when under acceleration it feels like its choking or starving or something once cruising speed is reached it isnt as noticeable its a manual i dont no if thats relavent or not. my thoughts were that he may not have got the timing correct but if its in neautral u can rev the shit out of it and doesnt seem to happen any ideas greatly appritiated

if it has only started after you new dizzy was installed
i would be checking if the leads are on in the correct order , sounds like its breaking down under load

probably wouldnt hurt to re check your timing, just remember it has to be set in diagnostic mode

had the same problem. threw some reco injectors and new oxy sensor at it and it's good as gold

check your fuel pressure and fuel contents may have weak pressure or stale fuel ....
