3.4 V6 Hilux slowly losing power and engine shudders under acceleration

Unread post by HJ75sam » May 30th, 2019, 10:57 am

My 2002 3.4 V6 hilux (205000 km) has slowly been losing power over the last 6 months or so. It can barely hold 90km/h up any kind of hill. Acceleration is slow and when I put my foot down the engine shudders, almost like when you're about to stall but at 1500 - 2500 rpm. Starts and idles fine. Fuel economy has improved over this time, getting around 550 km till empty, not sure if its related. Was hoping someone could point me in right direction as to what might be wrong.
