Thank you !
I changed coils and cables to Accel___ Spark plugs NGK-TRS RV-Power
The truck was running fine, but ever since I changed this_It has been getting an intermitent power failure...
I could be going 70 mph and next second down to no more than 40 mph...no more ! very scary on the highway !!!
What did I do wrong ?
Things I did to try to fix the problem: :
1-Changed Fuel Filter, notice the line from filter to engine is rupture_no leaks though.
2-Cleaned the IAC
3-Cleaned the Mass Air Flow Sensor
4-Changed the PCV
Valve_ It had a Motorcraft Brand in it.
5-Changed the Brake Booster Vacuum Gage thinking it could be a Vacuum leak.
6-I check for Vacuum leaks with Carb cleaner method...Nothing !
7- Changed the Fuel Pressure Regulator.
I sincerely would appreciate your help.
