no the boots coils are the olds blacks , I think the old garage make a mistake and fits a 4.6 plugs in my 5.4 , at the first 2000 km runs relatively good "some missfires" , but know with 5000 runs like ****. I get out the plugs and find the plugs was fitted without nikel and some coils are with insulating tape !!! Well here in mexico this will be the rule, i go to at least 5 garages and all is a **** service, include the oficial ford.
Now i will buy the correct sp515 sparks, and a set of accel coils, i will change the fuel filter , and fits a kn air filter, and will do the work myself.
Another problem is the trucks comes with a 2,5 magnaflow system with two cats , but one cat is empty , the Right side cat is empty , I think the Right bank has some fuel problem and volatilized the Right car, Left are good. I need find and fit a Two similar Cats.
Other problem is the transmision runs "rarely" , when you start the truck and select from "P" the "D", the truck engadge the gear and 1 second later disengadge and fits neutral , if you hits the gas the transmission engadge the gear but suddently !! Any had this problem ?
And the last problem, I fit a SCT Livewire dash and some months ago the sct runs good , read the fail codes etc , From the last entry on the last garage , they deleted all codes , but know the ecu dont flash any code, and the ecu dont received any fail codes, I disconect fuel inyectors running the truck and no fails was showed, plugs , etc ... The truck come with no cats and dont flash any fail codes .... Anyone know what happen ? or can be the Fail Codes deactivated ?
Here a pics of SCT and the fuel info of the dash 9 MPG , The truck is with a great overfueling, but this dont be show in the datalog SCT , short and large fuel trims are ok ? are this values normal for a truck running overfueling , I think no why the fuel trims looks normal ? o2 sensor can be bad ?
