Introduction + Need help on a 4.6is Misfire problem.

[ChumChuck]

First of all I'm Charles!

Originally from Québec but I recently moved to Whistler, B.C. This is my second 4.6is .. Yeah I know.. My wallet hate me! I just love this truck and for the price no SUV can beat that! Anyyyway!

So let begin with my first 4.6is. Had it for 4 months until my dad totaled it. It had M3 wheels for winter and other then that it was stock.








Now the new beast!

Only mod so far are yellow highbeam and fogs, X pipe, semi gloss OEM Style 87's and Inno Roof box.





Now the really important part, my misfire problem! When I cruise 100km/h and I go uphill in 5 the truck give me some misfire.. Downshift in 4.. No problem. So far I changed tranny oil + Filter (OEM),cleaned my MAF, Spark plugs .. I have no check engin code.. Please don't tell me it's a torque converter problem.

Thanks Guys,

Charles
