I have replaced 4 oxygen sensors in the past year and a half. The truck is sluggish and slow to accellerate, it suddenly kicks in and has power at 50mph. Could it possibly be fuel injectors need to be replaced? It's driving me batty! Mike

O2 sensors have no effect on this issue.

Check fuel pressure. Check cat converter back pressure.

What is the timing set at?

What motor?
