Loss of accel power

[theDefiant1]

Driving across to Narrogin (country WA) a couple of days ago, I encountered a strange one:

Whilst cruising at 110kmhr, the tone of the engine changed very slightly, and I felt (I think) a bit of a twitch through the accelerator pedal. Noticing this, I tapped the accel pedal which would normally see the car jump from, say, 110 to 120 quite quickly, but instead the response was dismal. A very slow increase in speed, and the car seemed to labour to it. I pulled over, swtiched off, checked fluid etc, no overheating... nothing. Started up again, and the problem was gone. Hooray!

A few hours later, same thing happened again - lost accel power. I came to the crest of a hill, put the car in neutral and coasted down. At the bottom, back into gear to accel out, and everything was fine again.

Addt: I also checked the air filter

So, any ideas?

BTW, I was privy to a few laps around the speedway there and hit 160 at the top of forth (was a slight decline tho).

sounds like a weird case. from a wild guess maybe it could be a glitch in your ecu. does anyone think otherwise?

Try doing an ECU reset and see if it does it again. If it does take it to Toyota and get them to put the scanner on it and see if any fault codes come up.

Check your battery and alternator.

This sounds like what mine is doing down low intermittently , can you still engage lift???

Lift is working perfectly, but there was no chance of hitting it during these two 'attacks' unless I dropped to 2nd or 3rd, not that I tried.

Maybe its the fact that you were cruising for a while, and the ECU put itself in fuel economy mode??

I thought my car at one stage was losing power when in lift.......but then realised that I didn't push the pedal all the way to the floor

Update:

Toyota humoured me and checked for any error codes. Car is in perfect health. No issue with fuel quality or delivery either.

So it may be as Superthai said - fuel saving mode (never knew it had it!). However, this did not happen crossing the Nullarbor. Anyway, since I will be doing the 200km commute regularly, I guess we will see if it happens again.

I find that If I've been driving it gently for a while the response and power is not very good.

But if i've been driving it hard then its response and power is much much better.

i notice that too if im jut cruising it for a bit then decide to go hard it doesnt seem to perform the way it would normally.......weird
