Rav4 Miss

[trikerwayne]

i have a missfire on my 99 rav4 only just before and just after 2000 rpm has anyone had this problem ?

Is yours a petrol or diesel engine, and when does the misfire occur - on accelerating, cruising or decelerating? Is it just the odd hesitation, or major hiccups? Engine cold, warm, both? What mileage has it done and has it been regularly serviced?

I've got an 07 D4D which gives the occasional hiccup when under very light load at around the same rev range that you indicate. No fault codes, it's had new injectors fuel pump, filters and ECU reset - still no fix. Next step is for garage to take readings from the ECU and analyse them.

check the coil pack for the right resistance

and tps for steadyness

hi,its a petrol it happens hot or cold at 2000 rpm

its throttle position sensor

its is basically a variable resistor so when you press the accelerator it changes resistance which gives a different voltages which the ecu reads and adjusts the fuel

ok thanks will get the coil pack and tps checked,will let you know how it goes
