98P71CROWNVIC

ive got a 98 p71, ive replace the spark plugs plus the fuel filter, but for some reason when im not "gunning it" and just barely getting up to speed it jerks before it shifts, sooo before i take it to a transmission shop and ask to check it or even break it open i was seeing if it could possibly be anythign else? would injectors play a roll? it doesnt idle bad, starts without any problems, no problems going and back up just when it shifts in the lower gears is when it acts funny..

funny mine does this sometimes when the a/c is on but it used to do it ALOT just driving not even when a/c on. i work at chevy but we also have a mazda dealer which computer will scan a ford. so i scanned it with the osciolloscope i cant spell ha and i found like 3-4 coils that were acting up so i got a few used ones from a buddy who changed his motor but kept 2 coil setup and changed now it runs better but when the a/c is on it feels like it struggles to get out of its own way. if anyone has any insite on that please let me know.
