I have 1993, 3.8 SCh Bonny. I've noticed that acceleration capability very in depends on engine temperature. I mean after short time driving - acceleration is well enouth but after long (after 30-60 min) at the higher temperature - sluggish and from time to time even like if I have taken the truck in tow. Thus all inconveniences begin at hi temperature of the engine. What can it be? Fuel pump, plugs, wires, coils are new. Fuel and air filters too
. I have the problem with high mileage (seems of NGK O2sensor
Thank you very much in advance.
I care this because I love driving Bonny
