1989 holden commodore sputters while accelerating Sign In

3.8 v6
270,000k+ ... odometer doesnt work

filled up with gas in the middle of know where. drove an hour, then the car started to lose power and shudder if i hit the gas. if i ease into it i can accelerate. when i down shift i get more power and can climb hills...

I've recently changed the oil, there is no water in it. I changed the plugs, not the wires... plugs looked good. recent air filter change... its still new. I changed the fuel filter yesterday and refilled half the tank. I also poured in a bottle of fuel system cleaner. the car ran better for about two hours then it ran as bad as the day wore on...

Im on a road trip doing 300 to 400 kilometers a day. what would you guys recommend doing next

We don't have any specifics on that car but the first thing you need to do is take a fuel pressure reading with an accurate gauge.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
