i have had this problem for about 3 months. The car misfire when there is a load on the engine but when i reved in neutral it wont misfire or bog. there are no codes that are showing i have cleaned the MAF that didnt help. i took it to a shop and after 100$ they told my that cylinder #1 and #5 are intermediate misfireing so i replace those injectors and still have the problem and that is where i am now. Can anyone help me!
 


If you have the original wires on it change them. Old wires can "crossfire" and if it's a '99 it's time anyway. #1 and #5 run in the same plastic loom across the front of the valve cover. You can get OEM wires from ZZP for $35 or it's a dandy time to upgrade.

Next, change your coils. They run about $25 each. I would be surprised if it was an injector problem.
Sounds like a problem I had with my F350 SuperDuty. Ran fine from 0-37 miles per hour. Anything over that and the truck bogged and kicked. It would NOT set a code. Turned out to be the #6 coil (It was a V10). Changed the coil and problem solved.
 


Spark plug wires. Plug wires carry high voltage and degrade over time. Injector wires carry low voltage signals, no more than 12 VDC, and last indefinetely.
 
replace the plugs too. i agree that its probebly the wires but do the plugs. the cold autolite plugs from autozone will run you $11 for the set
 


or unbolt the front dogbones and pull the engine forward.. then slip the bolt back in to the other hole in the bracket..
