My 280zx (standard set up) is running poorly, here are the symptoms:
Anyone had similar symptoms? Don't really want to splash out on a Fuel Pressure Regulator until I have made a few other checks first.
- Engine starts straight way, no problem
- Engine ticks over OK
- Give it a bit of throttle and it misfires, like its running on 5 cylinders
- When driving the lumpy running is intermittent, usually under load
- Once the car is fully warmed up it runs sweet, only very occasionally has momentary power dips (once in ten minutes for half a second)
- It has had a new fuel pump (the old one was squealing like a piggy, then died)
- All leads are newish Taylor ones from Mr.F, and seated properly
- All plugs have been checked and set
- Dizzy cap and rotor arm are good
- Cant see any problems with vacuum hoses/dip stick/oil cap
- 97 Ron petrol is fresh
- Battery is new and charging as it should
- Exhaust is new and sealed
