Bad miss in a 03 4.6

[ojsherbergt]

have a pretty bad miss i thinkit might be a foul plug cause i just replaced the coil packs that were going bad any other suggestions would be a ppreciated

[slow86fiveoh]

Could be fouled plugs if they weren't changed when u did the coil packs or u might have gotten a bad coil pack if they were from somewhere like autozone they are notorious for bad electrical products

well i just changed all the plugs so i think it a might be a bad plug in the group or and didnt even think of a faulty coil pack im go to have a diagnostic ran on it today to be sure if thats what it is

[ojsherbergt]

well changed the coil packs and its not as bad as it was before and i checked all the plugs and made sure they werent faulty but its still missing im thinking maybe either a vacum leak or could possible be a bent push rod or a burnt valve any addvice any one ????!!!!


:AR15: mustangs 2v :mad:

4.6 engines with the plastic intakes are bad about cracking and causing vaccum leaks, it might be worth looking into

[ojsherbergt]

i will look into to that im going to try and reset the computer to see if its a computer error if not i will look at the intake and the vacum lines tommorrow

[ojsherbergt]

found out it was the computer
not sending spark to the coil packs

[ojsherbergt]

got it fixed runs better then when i first got too bad the strut broke when i was taking it around the block fml :bangwall:
