How are the tune-up items: air filter, fuel filter, plugs, wires, cap & rotor?carmine34 said:I have a 2002 Frontier with a 4 cyl. auto 42k, when I accelerate heavy from a stop it just boggs and jerks, but if I accererate slowly it seems fine. When I put it in reverse, it chirps the tires and has no problem. Is anyone familar with this problem? Thanks!
Any engine codes showing (O2 sensor, etc.)?
How about the timing?
