Problem with engine misfire at mid throttle and under load
I had posted a note about our 2003 5.4L engine misfiring at mid throttle and under load earlier. I wanted to do a follow up but somehow it has dissappeared.
FYI I had originally thought that this was a fuel side problem (ie, water in gas, clogged jets, etc)but could not find a remedy . Local shop in Bangor did a code check that basicly said we had to take it into Ford for the diagnostics. This was not a cheap fix ($470). They found that two of the sparkplugs and coils needed to be replaced. So far we have driven 4000 miles and have not had any similar problems emerge.
