Customer Question

2002 F-150, 4.6 W, with 164,000 miles. Vehicle stutters or acts like it is skipping during idle, when accelerating and a little when just cruising. I have replaced the fuel pump and fuel filter. Went to a transmission shop to eliminate the possibility of a torque converter going bad. Not getting any codes and the check engine light is not on.

Hello and welcome! My name isCustomerand I can assist you with your question. Have you had a basic tune up done to the vehicle? Maybe you just have bad secondary ignition components causing the engine to run rough.

Actually, I installed new plug packs (Accel) and plugs. Possible that one of the packs is bad. However, this was a sudden occurrence (4 months after installing the packs and plugs). Drove to the store with no problems. I left the store headed to work and the truck started skipping. A few minutes ago, I just pulled the line off of the EGR and the truck continued to idle normally. I put the line back on and then pulled the line from the solenoid. Got vacuum from the engine side. I then pulled a P0403 code. Bad EGR?

It is possible! Also, just because the plugs are new does not mean they are good. I have seen bad new plugs right out of the box
